  • Mounting plates attach with anchor bolts to a standard 6-inch reinforced concrete floor, or to new foundations for special load conditions
  • Smaller capacity cranes use square mounting plates with welded gussets connected to the mast; each plate uses four anchor bolts
  • Larger capacity cranes use hexagonal mounting plates with welded gussets connected to the mast; each plate uses 6 anchor bolts

What is a jib crane?

A type of crane, which has a horizontal member (known as a jib or boom) that supports a moveable hoist fixed to a wall or to a floor-mounted pillar is known as a jib crane.

Used mostly in industrial premises and on military vehicles, the jib may swing through an arc, giving additional lateral movement. It can be also fixed. The jib cranes can be also fitted on top floors of warehouse buildings to help lift goods to all floors from the ground to the top. The jib is an operating arm that extends horizontally from the crane.

The jib on a jib crane is a tilted strut that supports a fixed pulley block. Cables wrapped multiple times round the fixed block and round another block are attached to the load.

The free end of the cable is pulled (manually or using a winding machine), and the pulley system delivers a force to the load equal to the applied force multiplied by the number of lengths of cable passing between the two blocks. This number is known as the mechanical advantage.

Overhead Crane Types: Overhead travelling cranes, designed for handling loads up to 120 tonnes, are the ideal solution for heavy lifting and wide spans. The overhead travelling crane range includes four series designed for different applications and operating conditions: single girder, double girder, underslung and single girder wall travelling cranes.

Electric overhead travelling crane

EOT crane types:

Overhead crane types: Material handling is a vital component of any manufacturing system and the material handling industry is consequently active, dynamic, and competitive.

A crane is a mechanical lifting device equipped with a rope drum, wire rope, and sheaves that are used both to lift and lower materials and to move them horizontally.

It uses simple machines to create mechanical advantage which helps to move loads beyond the normal capability of a human. Cranes are commonly used in the transport industry, in the construction industry, and in the manufacturing industry.

The overhead cranes handle and transfer heavy loads from one position to another. Electric overhead traveling cranes are widely used in many industries for lifting the safe working load.

The escalating price of structural material is a global problem. Many small scale industries purchase the existing electric overhead cranes from bigger industries and make the required modification to suit their requirement.

Types of overhead cranes

Overhead crane types:

Various types of overhead cranes are used in industries with many being highly specialized. Various types of overhead cranes are single girder cranes, double girder cranes, gantry cranes, and monorails.

Single Girder Crane

The crane consists of a single bridge girder supported on two end trucks. It has a trolley hoist mechanism that runs on the bottom flange of the bridge girder.

Double Girder Crane

The crane consists of two bridge girders supported on two end trucks (end carriages). The trolley runs on rails on the top of the bridge girders. Double girder electric overhead cranes are widely used in the industries because they can carry more loads with more span than any other type of crane. In this project, we are concentrating mainly on double girder electric overhead cranes.

Gantry Cranes

These cranes are essentially the same as the regular overhead cranes except that the bridge for carrying the trollies or trolleys is rigidly supported on two or more legs running on fixed rails or other runways. These “legs” eliminate the supporting runway and column system and connect to end trucks which run on a rail either embedded in or laid on top of, the floor.

Monorail cranes

For some applications such as production assembly lines or service lines, only a trolley hoist is required. The hoisting mechanism is similar to a single girder crane with a difference that the crane doesn’t have a movable bridge and the hoisting trolley runs on a fixed girder. Monorailbeams are usually I-beams (tapered beam flanges).

Monorail or repair trolley cranes are used for maintenance purpose.

For maintenance of any single or double girder crane, the crane which is to be taken for maintenance is brought under the repaired trolley (monorail) crane so that it can lift the components of the crane for repair or replacement.

EOT Crane

The EOT in EOT Cranes stands for “Electric Overhead Travelling”. These types of overhead cranes are stationary and allow for lateral movement across two planes. Not only do they move backward and forwards but they can also move up and down with the load. These cranes are perfect for indoor work.

Factories, assembly lines, big warehouses, mining corporations, etc. can make good use of EOT cranes. Low maintenance and easy to operate make these cranes a good investment, especially if you have trained operators and experience the frequent need for heavy load lifting. The only thing to keep in mind is that they are not to be used in explosive and corrosive environments.

HOT Crane

Here, the HOT in HOT Cranes stands for Hoist One Track. HOTs are a stationary overhead crane and allow for lateral movement across two planes as well. They are less common as compared to EOT cranes as they do not allow for as much movement as the EOT cranes.

They are more commonly used for maintenance purposes. They have a hoist attached to the bridge which can be operated using an electric pendant. They are low maintenance and a sound investment if you frequently need a lot of maintenance and repair in your enterprise.

Bridge Cranes

Overhead bridge cranes are the most common models on the market. A bridge crane has two overhead runway beams that are linked to the support structure of the building. This crane comes in two configurations; single and double girder. The strength of a double and single girder bridge crane is almost the same. However, a double girder allows you to hoist a load higher than a single girder crane. Because a single girder is simpler, it is easier to install and cheaper than a double girder.

Gantry Cranes

In a gantry crane, the girder stands on legs as opposed to being suspended on a support beam. The legs can be fitted underground or on the surface. Gantry cranes are suitable for outdoor use because they don’t require the girder to connect to a building’s support structure. If you need a crane in a shipyard, a gantry is the right kind of system.

Workstation cranes

A workstation crane is built for lightweight use in areas with space constraints. It’s a simple design that can lift between 150 pounds to 2 tons of material. Workstation overhead cranes are perfect for repetitive duties like moving packaged boxes in a warehouse. They are ergonomically-designed for regular use. (Overhead Crane Types)

Warehouse crane types

Overhead crane types: Top running vs. under running cranes

When it comes to defining clear differences between bridge cranes, you will want to consider if you require a top running or under the running crane.

On a top running crane, the bridge runs on rails along the top of the runway beams.

On an under-running, or underhung crane, the bridges are supported by the bottom of the runway beams and the wheels run along the bottom of the lower beam flange. (overhead crane types)

Top Running Crane

These cranes have no limiting capacity, meaning they can be built to go from small capacities to very large capacities. They include a rail installed on top of each runway, and the bridge wheels move on the rail instead of the bottom flange of the runway beam. These cranes are supported by the building structure or runway support columns, or sister columns, and are ideal for moving extremely heavy loads.

Under Running Crane

Often called “underhung,” because the crane wheels are supported by the bottom flange of the crane runway beams acting as the crane rail. These types of cranes can allow you to maximize your facility’s floor space for the production and storage of material because they are supported by the ceiling trusses or the roof structure. Or, they can be designed to utilize an existing support structure (if adequate), or run on a newly-engineered support structure.

Electric overhead traveling crane

Overhead crane types: Electric overhead crane comparison:

• Based on Safe Working Load: Double girder cranes can lift the loads up to 500Tcapacity. Single girder cranes are suitable for the low-safe working load. Because of the extra girder in double girder cranes load is distributed in two girders and hence double girder cranes can carry a safer working load than single girder cranes.
• Based on Span: For a longer span, double girder cranes are used whereas single girder cranes are useful for a smaller span.
• Based on Application: Double girder cranes are efficient for intensive use. Because of the rigidity of the structure, they are used in extreme conditions like lifting molten metals. Single girder cranes are used for irregular and light use. They are used in small workshops, storage areas, etc.
• Based on Long Travel Speed: The single girder cranes are suitable for lower long travel speed whereas the double girder cranes can run with higher long travel speed.
• Based on Cost: In general, single girder cranes are less costly than double girder cranes. Double girder cranes consist of more walkways and other accessories that add to the cost. Single girder cranes cost less in many ways, only one cross girder is required, the trolley is simpler and installation is quicker.

Different types of overhead cranes

More on this story

The overhead crane needs several components to lift loads, including the hoist. The design and loading of this equipment correspond to the needs of the job.

A hoist is a machine composed of a system of pulleys that allow lifting a load exerting a force less than the weight to be moved.

A hoist is a device used for lifting or lowering a load by means of a drum or lift wheel around which rope or chain wraps. It may be manually operated, electrically, or pneumatically driven and may use chain, fiber, or wire rope as its lifting medium. The most familiar form is an elevator, the car of which is raised and lowered by a hoist mechanism. Most hoists couple to their loads using a lifting hook.

What is an overhead crane?

Overhead cranes are mobile tools designed to carry cargo from one place to another, they are suspended at high altitudes, generally above 15 yards. The displacement of the traveling cranes can be horizontal or vertical.

• Overhead crane hoist
• Overhead crane parts name

What is the hoist?

The hoist or rig is a machine composed of two or more pulleys and a rope, cable, or chain that alternately goes through the various throats of each of those. They allow lifting a load exerting a force less than the weight that must be moved.

How do hoists work?

The use of the pulleys minimizes the effort required to move the load. They can have different sizes or lifting powers.

The small ones are manipulated manually and the bigger ones have incorporated an electric motor to make them work.

Depending on the load to be loaded or unloaded there are many types of hoists.

Some are electric, others use manual force or levers to exert their power with the help of chains, cables, branches, hooks, clamps, magnets, and other accessories with similar characteristics.

What is a hoist used for?

A hoist is a tool that is used in workshops to lift or move loads easily.

Its utility lies in the fact that it is hardly necessary to apply force to move a weight, for this reason, the hoists are usually attached to a rotating arm that is coupled to a machine or on the roof of the workshop, fulfilling different functions.

The hoist has a different lifting capacity depending on the load that can be lifted.

This capacity can be increased by increasing the number of branches. An example: a hoist with a branch that can lift 500 kilos can be extended with another branch to raise 1,000.

The hoist is controlled by a control panel that must be perfectly visible and easily understood by the operators:

• Green or white button: On
• Red button: Stop
• There is usually another button for the emergency stop, red on a yellow background. The stop order has priority over the others.

Lifting hoisting equipment

Where are the hoists used mainly? For lifting and moving heavy loads, hoists are usually used together with a crane in:

• Mechanical workshops: in hobbies, hoists are used to lift heavy parts of vehicles, for example, the engine.
• Metallurgical industry: the large containers in which the metal is cast are transported from one side to the other by means of hoists.
• Warehouses: when packing products or merchandise in large quantities or very heavy concentrations, the hoists are used. Also at the time of classifying and inventorying.
• Airports: hoists are used at airports to move luggage and to transport it from the warehouse to the plane and vice versa.
• Maritime ports of embarkation and disembarkation: here its function is combined with that of the cranes. Hoists transport loads between ships or from one part of the ship to the other.

Types of hoist

They can be classified according to these parameters:

According to your number of throats:

• Simple rigging. When one of the pulleys has only one throat
• The rest are called double rigging.

According to the way in which they multiply the force:

• Factorial: the greater the number of moving pulleys, the greater the force applied.
• Potential: multiply the force by 2 and raised the number of pulleys.
• Differential: the force depends on the difference between the length of the radius of both pulleys.

According to the material of the branches:

• Of rope.
• Of cable.
• Chain.

According to the power applied to the machine:

• Manual.
• Hydraulics
• Electric

Industrial hoist

The correct use of a hoist: One of these frequent risks are falls or projections of objects, which can be caused by defects in the mechanism or by unforeseen circumstances. Therefore, it is essential to follow some safety tips:

• Periodically check the elements responsible for lifting, to check that they are in perfect condition (for example, check that there are no breaks or signs of wear in the links of the chains). These elements must be made of strong and resistant material, mainly forged steel.
• The chains or lifting elements will be placed on shafts or pulleys that have grooves, to prevent them from twisting when rolled.
• You also have to monitor the hooks, since they are responsible for preventing the load from falling. They must also be wrought iron and incorporate some security elements, for example, latches that ensure the load.

Chain hoist safety practices

Precautions for using a hoist:

• Check the maximum user load of the hoist and do not exceed it.
• Make sure that the chains and metal cables have the proper lubrication.
• Immediately replace any worn metal chain or wire. Label any defective chain or cable and keep it out of service.
• There are hoists that can be driven in different directions but even so, it is preferable to pull as straight as possible. Lateral traction increases wear and can even be dangerous.
• Follow the maintenance program recommended by the manufacturer.
• Make sure there is no person around the load before lifting it.
• Avoid tilting the load since it can become unstable.
• Avoid lifting the load more than is really necessary.
• Do not leave suspended loads unattended.

Overhead crane safety

General practices in the use of a hoist: When operating a hoist, there are certain practices that must be followed. When this tool is used, there is an operator and, in some cases, an assigned supervisor or a bookmark.

All persons involved must understand the procedures for the control and execution of maneuvers with the hoist.

The operator must be familiar with the characteristics of the equipment, as well as understand and follow all the safety rules.

Safety first

A hoist, crane, or forklift must never raise a load greater than the capacity for which they are designed. The only exception is for evaluation purposes.

If a hoist is used for standard lifts that require more than one person, there must be a marker.

This person must be at the lifting site throughout the operation. If only one person operates the hoist, she takes full responsibility.

The designation can be made in various ways, including detailed verbal instructions, written instructions and responsibilities that are clearly defined in the organizational structure of the team.

Supervisor responsibilities

The responsibility of the supervisor is to ensure that the people involved in the operations with the hoist understand the correct way to hoist.

This ensures that the weight of the load and the safe conditions of the site are determined in an appropriate manner.

The supervisor must ensure that the hoist is properly prepared, located, and operational. You must also assign a bookmark when necessary.

In addition, the supervisor is responsible for ensuring that all lifting operations are efficient and safe.

If any potential danger is identified, the supervisor must stop the operation. If an accident occurs, the supervisor is the person to turn to.

Overhead operator

Pointer and operator practices: The leader directs the lift, and ensures that the load is balanced and secured before being raised more than a few centimeters.

It also checks the load path for possible obstructions.

The operator also has an important role. For example, before starting the lift, make sure there are no kinks in the chain or cables and that multiple lines are not rolled.

If there is no full stretch in the chain or cable, the operator of the hoist must adjust the line on the gear wheel, on the pulley, and so on until the loose part has disappeared.

Electric winch hoist

Differences between a winch and a hoist: the winch allows horizontal displacement of the load.

Probably these two computers have a similar appearance, however, they are manufactured for two different purposes. This equipment is designed to pull a heavy load horizontally on a slightly inclined or level surface, greater than 45 degrees.

The use of a winch or a hoist can make heavy lifting tasks easier.

How do the winches work?

Winches are devices used to wind a cable or rope in or out.

Most winch drums are made of steel, they consist of a rope or cable wound around a drum or cylinder. This equipment can move cars, boats and heavy parts much more complex.

How do the hoists work?

To lift heavy objects, such as a motor block or construction material, which requires lifting or lowering a load, a hoist must be used.

Hoists are typically made of motors. Powered hoists include all those that are driven by electricity, hydraulics, pneumatics, or manually operated.

Electric chain hoists are ideal for mechanical and chain hoists are recommended for lifting heavy materials in flammable environments.

Break system

The main difference between a winch and a hoist is in the braking system. The most offroad system is designed to automatically maintain the load. A dynamic brake uses the gears of the braking system. The winch cable could wear out slightly under a heavy load.

If a winch is used as a hoist, the load could fall, creating a risk of danger, or the lifting gears could use a mechanical braking system, which is a physical break that blocks the available reel mechanism in a hoist.

Some winches are specially designed to work like a hoist. In order to slow down and not have a free spool mechanism. Never use a winch like a hoist unless the manufacturer recommends it.

More on this story

Overhead crane equipment parts can be broken down into four main categories:

• Power systems and motors
• Electrical parts
• Mechanical parts
• Controls

No matter the make or model of your material handling equipment can provide universal overhead crane parts from these four categories to support high-value equipment such as satellites, heavy equipment such as turbines, and difficult load-lifting configurations such as aircraft assemblies.

To keep your overhead cranes, hoists, and trolleys in service, the availability of interchangeable replacement crane parts is paramount; but first, having a solid understanding of these components and their various functions is crucial to limiting production downtime and preventing emergency situations.

Crane components

This type of overhead crane is used in those plants where the lifting and transport of heavy equipment and/or accessories through a work surface are required.

They are used in the steel industry to transport large products such as coils, in the automotive industry to assemble automobiles and in the paper industry, they are used to maintain heavy machinery. These overhead cranes consist of three main parts:

Bridge crane

Bridge girder: It is basically the whole mechanism that causes the translation movement.

It is the structural part of the crane formed by steel beams, A-36 steel is generally used (ASTM structural steel standard), made from plates, it is one of the biggest and heaviest elements in the crane. The bridge moves by means of rails along the nave in a direction perpendicular to the lanes.

• Overhead crane manufacturers
• Overhead crane design

Trolley frame

It is the mechanism that holds the lifting system has moved from the inside out and vice versa.

The structure that supports and houses the components that form the lifting system for cranes equipped with an open winch or to support the hoist for cranes equipped with this type of component.

It can be built as a unit or in sections depending basically on its weight and dimensions.

Its shape, dimensions, and weight are variable since they are designed and built according to the needs of each crane, which vary according to their load capacity and type of service.

Lifting equipment

Hook block: It is the part responsible for carrying out the movements of lifting and lowering of the load.

Runway rail

A structure whose function is to support the bridge beams of the crane, and by which the displacement and guidance of the same are affected.

Rail tracks can be designed by IPR profiles (structural beams), as dimensions are required.

End truck

Metallic structures whose function is to support and hold together the beams of the bridge of the crane, in addition to housing the driven and driven wheels of the bridge.

The construction of the heads can be formed by a single unit to support the number of beams that have the bridge or in small and independent for each beam of the bridge.

Overhead crane components

Electric Hoist

It is the lifting device of the crane, it moves along with the bridge on which it is located. The hoist, in turn, is housed on another rail that allows it to move to position itself between the two main rails.

Chain hoists and trolleys

Chain hoists are chain motors used to lift loads. The trolleys displace the hoist or hand hoists.

Hoists with steel cable

The hoists with steel cable are motors coupled to a drum where the steel cable is wound in a drum which has a hook that lifts the load of a crane.

Cabin crane

The cabins are used in overhead cranes so that the operator has greater visibility in the field of work and thus facilitate the maneuver of loading and unloading.

Heads or heads

The heads of the crane are the structure where the wheels of the cranes are placed with their gear motors for the transverse movement along with the ship.

Wheels and modules

The wheels are placed inside the heads that move the bridge or the truck of the crane.

Rubber stops

The rubber stops have the function of cushioning the blow of the structure of the bridge or the car.

Overhead crane types

Types of overhead cranes or bridge crane: These types of cranes are used to move tons from one place to another, usually, they are handled by two operators.

Gantry Crane

This type of cranes is similar to the overhead ones, the difference is that they are installed at a lower height.

Overhead Wall

This type of crane differs from the previous two, is attached by one end to the wall, its support capacity is very low.

Overhead crane design

In addition to simplifying some of the processes described above, there are two main reasons why a company would want to install an overhead crane, or a series of overhead cranes, in their facility:

Efficiency: Overhead cranes are more efficient than using a group of workers or tow motors to lift and move material and can work up to 2-3 times faster. Think about how a manufacturer, mill, or warehouse can streamline their processes and procedures by introducing an overhead crane to automate the lifting, maneuvering, and unloading of materials at their facility.

Overhead Crane Safety: Another advantage of installing an overhead crane in manufacturing, assembly, or warehousing facility. Cranes can be used to lift and move materials in extreme environments and can handle corrosive or dangerous materials like hot metals, chemicals, and heavy loads. A workstation or jib crane can be put in place to help workers move heavy objects in a controlled manner and help cut down on repetitive motion injuries and muscle strains.

Bridge crane parts name

Cranes lift and lower loads with a hoist that is attached to a trolley. The trolley moves back and forth along a bridge. The bridge moves along a runway. Some cranes – such as a jib crane – don’t have a bridge but still have a hoist attached to a trolley and can move a load in a horizontal direction.

A bridge crane is defined as a crane, fixed or able to move along a track(s) having at least one primarily horizontal girder and equipped with at least one hoisting mechanism. There are four main types of overheads cranes – top running, under running, single girder and double girder.

How does an overhead crane work?

What is the difference between a gantry crane and overhead crane?

• A gantry crane is slightly different from a bridge crane. The general premise is the same, but the operation is different.
• Some gantry cranes ride along a track installed on the floor or use a V-groove caster to keep moving in a straight line.
• Gantry cranes are usually less expensive than an overhead bridge crane.

What is the difference between Crane and hoist?

• A hoist is a device used for lifting and lowering loads while a crane is a device used for moving loads in different directions.
• The hoist is a simple device while a crane is a more complex device.
• A hoist can only move loads vertically while a crane can move loads vertically and horizontally.

Overhead Monorail Crane: With an overhead crane warehouse monorail system, the hoist and trolley run on a single stationary beam. The monorail allows two axes of hook movement: up/down and forward/back along the monorail beam.

Because of their inherent speed and efficiency, monorail material handling systems are an effective method of moving and positioning loads to specific locations. They are available in various capacities.

Monorails are best used in applications where materials are to be transported from one fixed point to another fixed location, or through a process.

Monorail Crane

These overhead cranes or bridge crane of European Standard is designed and manufactured according to the advanced FEM / DIN standards.

To begin with, the Monorail overhead Cranes have a compact structure with little pressure on the tires, which generates efficiency in small spaces or warehouses with limited space, to reduce investment in structure.

Monorail Overhead cranes are frequently used in the branch of manufacturing, metallurgy, ports, work stations, warehouses, to provide more efficient logistics solutions, especially suitable for places that require precise movements.

Bridge Cranes or Single Girder Overhead Cranes or known as the Monorail Overhead Cranes are a type of crane that is designed according to the FEM, DIN, ISO standard, however, they are widely used in the field of materials processing, metallurgy, oil, electric power, etc.

Therefore these cranes are manufactured specially for a place of assembly that requires precision for the assembly of components and the precise positioning of materials.

Monorail overhead crane

Monorail conveyor – monorail overhead crane – monorail crane design – Mechanisms:

• The Monorail is optimally designed, with box type design, the total length of the plate is cut and formed through the numerical control and its deviation is exact.

Monorail crane design

Overhead monorail conveyor systems – Monorail Cranes: Opportunities & Considerations:

Overhead crane specifications

Opportunity: Monorail cranes are most effective in production applications where materials are repetitively moved from one point to another. The monorail hoist and trolley run on a single stationary beam—a cost-effective alternative to a bridge or gantry cranes for applications that require limited lifting capacity.

Examples include assembly operations, transport of materials to workstations and lines where parts are blasted, painted or coated.

Monorails also serve as a material handling alternative in places that cannot accommodate a bridge crane.

Monorail beam design

Overhead crane design – Considerations: Monorail cranes provide only two axes of hook movement: up/down via the hoist and forward/back via the monorail beam.

If your application requires lateral motion, you’ll need to consider other alternatives such as a bridge or gantry crane.

Aided by your engineering team, can help you create a monorail system that maximizes efficiency and productivity.

Safety for the Good Operation of the Overhead Crane

In your company or workshop, for your efficiency, convenience, and safety. The cranes or overhead cranes are extremely important to perform the lifting task. They are very useful and popular in most industries; such as construction, metallurgy, mining, oil, chemical industry, production process, transport, rail, storage, logistics, etc.

Workplaces can be in factories, construction sites, warehouses, workshops, garages, iron smelting, port, etc.

Therefore, we want to offer you relevant information for your Crane and Hoist.

Safety rules:

• For each crane, signs of nominal weight must be hung in visible places for all collaborators.
• Check the overhead cranes and their components before starting to operate.
• When the overhead Crane is working, no one should be allowed to be on the bridge
• It is forbidden to use the hook to transport people, it is extremely dangerous.

Overhead crane hazards and control measures

Safe Working Load

For example, if your loads are always 1 ton, you should have a hoist that allows you to load up to 2 tons and not just have a 1-ton hoist, the risk is expensive and is considered an occupational risk.

• The operator without operation ID or under the influence of alcohol can not handle the crane.
• Adopt the necessary security measures according to your country.
• Do not throw things from the crane cabin, it’s dangerous.
• Check that limit switches and protection devices work normally.

• The equipment must be kept clean and orderly.
• Do not leave tools, explosive, flammable, or dangerous materials in the cabin
• Do not come up with food for it.
• Do not overload the crane, you should always consider a surplus before buying and installing the crane and the hoist.
• For the repair and inspection lights, their voltage should be below 36 V.

Restrictions. Equipment and Cranes must not work under the following conditions:

• The load is not tied properly.
• overloaded equipment.
• The signal is not clear.
• drag the goods obliquely.
• explosive, flammable, and dangerous materials without protective measures (unless you have special equipment for this type of load)
• There is great wear for the steel cable.
• the lifting mechanism would be damaged.
• You can not crash between overhead cranes. Do not use a crane to promote the movement of the other.

Functioning:

When the overhead crane is in operation, there should be no obstacle in the production line, and the height of the hook, spreader, and load must be at least 2 m above the ground. If you overcome the obstacles, the extra height must be more than 0.5 m.

Overhead crane inspection

• If you need to perform the inspection or maintenance, you have to cut off the electric power and place a notice for the collaborators. When it is necessary to work with energy, it is necessary to take security measures.
• It is necessary to make the technical safety checks constantly, in addition to planning corrective maintenance services for your hoists and overhead cranes.

Lifting maneuvers:

• For the lifting of very heavy loads, liquid metal, explosives and dangerous materials, you must lift them slowly first up to the height of 100-200mm and test the reliability of the brakes.
• It is not recommended to transport materials over people or machines.

Safety training

• Before use, ensure the crane is suitable for the planned hoisting task. Confirm it has appropriate travel, lift, and capacity.
• Visually and physically inspect the crane before use. Check for damage, wear, and proper operation of all functions.
• Confirm the load weight. Check the capacity of all equipment including the hardware, rope, and slings. Do not exceed these capacities.
• Select the right sling for each lift. Inspect slings and other rigging hardware before use for wear, stretch, or other damage. Do not use damaged or defective slings. Use softeners around sharp corners. Do not splice broken slings.
• When communicating with a crane operator, use clear agreed-upon signals. Except for the stop signal, the crane operator should follow instructions from only one person – a designated signaler. Where a wired or remote controller is used, the operator should become familiar with all of its functions before lifting the load.
• Warn all people in the load lift area before starting the lift. Ensure that the path of the load is clear of persons and obstructions. Do not lift loads over anyone. Center the crane hoist over the load before hoisting to prevent swinging of the load.

Operator training

• Slide the sling fully onto the hoisting hook and ensure the safety latch is closed. Do not load the hook tip or hammer a sling into place.
• Secure unused sling legs. Do not drag slings or leave loose materials on a load being hoisted.
• Keep hands and fingers from being trapped when slack is taken out of a sling. Step away before the lift is started.
• Move the load and controls smoothly. Minimize load swing.
• Walk ahead of the load during travel and warn people to keep clear. Use a tagline to prevent rotation or other uncontrolled motion. Raise the load only as high as necessary to clear objects. Do not ride on the hook or load.
• Set loads down on blocking, never directly on a sling. Do not pull or push loads out from under the hoist.
• Do not leave the load (or the crane) unattended while the load is suspended.
• Where crane operation by other personnel must be restricted, employ lockout and tagging procedures.
• Store slings off the floor in a clean, dry location on hooks or racks. Do not leave slings, accessories, or blocking lying on the floor.

Overhead crane inspection

Overhead cranes can be an integral part of a facility’s productivity. If a shop crane is out of service for even just an hour it can have a domino effect throughout the whole facility. That’s where inspections on the overhead cranes can be a critical service to keep the crane (and shop) running smoothly.

Most facilities will call in a company that services overhead cranes or an overhead crane service company.

Overhead crane service

Overhead crane service companies are great at servicing the electrical and mechanical components but they may not have the expertise or experience in structural inspections. That’s where a crane inspection company should be involved.

They have the experience and the tools to do a proper structural inspection. Also, if there are defects discovered during the inspection, crane inspection companies have the experience and knowledge of how to do a proper repair.

Overhead crane maintenance

What happens when there are structural defects in an overhead crane?

It’s not uncommon to find structural defects on an overhead crane. If a defect is not found in a reasonable timeframe it could propagate into a structural failure. If a crane is taken out of service due to a structural defect it could be inoperable for a couple of days for repairs.

It’s best to catch these defects before they become a major issue. A small repair can be performed in an hour and a large repair could have the crane shut down for a couple of days.

Overhead crane inspection checklist

When a structural crane inspector checks an overhead crane they are looking for cracks in welds, deformed structural members, and other defects that could affect the structural integrity of the crane.

They will look at the columns that support the crane way to make sure they don’t have any defects. The most common defect on the columns are dents that occur when a forklift or other machinery accidentally hit the column.

Next is the crane way itself. Once again the inspector will check for any defects in the structural members and welds. It is important for the inspector to have access to the full length of the crane way for a thorough inspection.

The Bridge will be checked for defects including looking for any negative camber in the bridge beam. On the trolley, they will be looking for any structural defects and check the wire rope for any deficiencies.

OSHA overhead crane

A person conducting a business or undertaking has the primary duty to ensure, so far as is reasonably practicable, workers and other people are not exposed to health and safety risks arising from the business or undertaking.

This duty requires the person to manage risks by eliminating health and safety risks so far as is reasonably practicable, and if it is not reasonably practicable to eliminate the risks, by minimizing those risks so far as is reasonably practicable. It also includes ensuring so far as is reasonably practicable the:

• provision and maintenance of safe plants including cranes, and
• safe use, handling, storage, and transport of the plant.

The Work Health and Safety (WHS) Regulations include specific duties for a person conducting a business or undertaking with management or control of the plant, powered mobile plant, and plant that lifts or suspends loads.

If you own a crane you are the person with management or control of that plant.

If you hire or lease a crane, you have management or control of that plant for the period you have hired it. Both you and the person you have hired or leased it from will have duties to eliminate or minimize the risks associated with the plant, so far as is reasonably practicable.

Overhead crane risk assessment

risk assessment checklist

Find out what could cause harm. The following can help you identify potential hazards:

1. Observe the workplace to identify areas where cranes operate and how they interact with other vehicles, pedestrians, and fixed structures like overhead electric lines.
2. Ask the crane operator, crane crew, and others about problems they encounter at the workplace including operation, inspection, maintenance, repair, transport, and storage requirements.
3. Review your inspection, test, and maintenance records e.g. logbooks, and incident and injury records including near misses.

Hazard assessment checklist

Assess the risk: In many cases, the risks and related control measures will be well known. In other cases, you may need to carry out a risk assessment to identify the likelihood of somebody being harmed by the hazard and how serious the harm could be. People who work with or near cranes are most at risk. Some of the risks when using a crane include:

1. structural failure, overturning, or collapse of the crane
2. contact or collision of the crane or its load with people or other plants and structures, and
3. falling objects.

A risk assessment can help you determine what action you should take to control the risk and how urgently the action needs to be taken.

Risk management checklist

Take action to control the risk. The WHS laws require a business or undertaking do everything reasonably practicable to eliminate or minimize risks.

1. The ways of controlling risks are ranked from the highest level of protection and reliability to the lowest.
2. This ranking is known as the hierarchy of risk control. You must work through this hierarchy to manage risks.
3. You need to consider possible control measures and make a decision about which are reasonably practicable for your workplace.
4. Deciding what is reasonably practicable includes the availability and suitability of control measures, with a preference for using substitution, isolation or engineering controls to minimize risks before using administrative controls or personal protective equipment (PPE).
5. Cost may also be relevant, but you can only consider this after an effective review of all reasonably practicable control measures.

The first thing to consider is whether crane-related hazards can be completely removed from the workplace. For example, designing items of size, shape, and weight so they can be delivered, handled or assembled at the location where they will be used without the need for a crane.

Event risk management checklist

If it is not reasonably practicable to completely eliminate the risk then consider the following options in the order they appear below to minimize risks, so far as is reasonably practicable:

1. substitute the hazard for something safer e.g. replace a crane operating cabin with a restricted field of vision with one that has a clear field of vision or use a remote control, for example, a pendant control.
2. isolate the hazard from people e.g. use concrete barriers to create an exclusion zone to separate crane operations from workers and powered mobile plant, and
3. use engineering controls e.g. enclosing the operator with a falling objects protective structure (FOPS) to minimize the risk of the operator being hit by a falling object.

If after implementing the above control measures a risk still remains, consider the following controls in the order below to minimize the remaining risk, so far as is reasonably practicable:

• use administrative controls e.g. schedule crane operations to avoid or reduce the need for pedestrians and vehicles to interact with the crane in the area of operation, and
• use PPE e.g. gloves, hard hats, high visibility vests, earplugs/muffs, and eye protection.

Check your control measures. Control measures need to be regularly reviewed to make sure they remain effective, taking into consideration changes, the nature, and duration of work and that the system is working as planned.
