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 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.

• Bridge crane
• Bridge girder
• End truck
• End truck bumper
• Runway rail
• Bridge drive wheel
• Bridge drive
• Hook block
• Wire rope
• Trolley festoon

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 Crane Components

A variety of OEM parts and components are available for overhead cranes and hoists.

Overhead Crane Electrical Components

Traveling cranes require circuit breakers, transformers, variable frequency drives, and surge suppressors, among many other components.

Overhead crane manufacturers in the USA

Some have wondered if in the United States they fix, manufacture, elaborate parts, and components of overhead cranes.

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.
• Low Trolley structure and reasonable size to the hook, allowing the reach of the wide crane application.
• Bow or flat wheels, anti-friction, honey type shock absorbers, and anti-derailment devices.
• 3-in-1 motor, speed control, force reducer, safe disk brake.
• Good performance, this way it works smoothly with the speed control of the steep less
• The shot-blasting machine reaches Sa2.5 after welding, thus relieving internal stresses to ensure the best performance of the main beam.
• Painted with epoxy paint rich in zinc and the thickness of the oil film is 140 μm.

Monorail overhead crane systems

Monorail overhead crane systems, electrical systems, safety procedures:

Electrical system

• In general, Food is through sliding lines.
• Phase protection; it automatically disconnects from the power source when the phase occurs.
• The Crane and the Hoist are mutually independent and can travel at the same time.
• The sliding contact line meets the requirement for power supply and adapts to agitation or movement.
• Corrosion-proof Control with IP54 grade protection
• Rugged plug
• The Electrical Components are equipped in a convenient position for optimal and convenient maintenance, in addition to having protection to avoid inadvertent contact.
• It has an electric power system type Festoon.

Overhead Crane Safety

Protection System:

• Reducer blocked to fall-proof.
• Outdoor hoist with rain cover
• Alarm indicator lights
• Anti-collision infrared

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.

Overhead crane inspection checklist

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.

Crane vs. Hoist: What’s the Difference?

First things first – a hoist helps to do one thing: move heavy loads up and down. An elevator is probably the most well-known hoist. Elevators are the perfect machine for transporting loads vertically, but in no other direction (unlike a crane’s functionality).

On the other hand, a crane can move in two or three dimensions. Overhead cranes suspend from a beam or move along a rail. Just like cement is a component of concrete, a hoist is a central part of an overhead crane. Essentially, the crane moves the hoist around.

suspend from a beam or move along a rail. Just like cement is a component of concrete, a hoist is a central part of an overhead crane. Essentially, the crane moves the hoist around.

Overhead hoist

Chain hoist crane – overhead hoist: Hoists and cranes are both machines that help move and lift heavy loads on the job site, but they have many fundamental differences in design and usage.

Below, we set the record straight about what each of these devices does, and how they work together to assist in your next project.

Chain hoist cranes are suitable for a wide variety of industrial and specialized applications.

Whether you need a work station crane, an overhead traveling crane or a rotating crane, chain hoist cranes are always the ideal choice.

• Overhead crane safety
• Overhead crane manufacturers
• Overhead Crane Cable

Hoist crane design

Overhead crane design – hoist crane design: It is understood that each client is different and so are their needs; custom cranes are designed and built to meet the individual requirements of your application.

You may want to buy a full chain hoist crane or upgrade your existing crane with an electric chain hoist. You can choose a single or double bridge beam crane for your work area.

A simple bridge beam crane can be a bridge type profile or drawer. A suspended crane can be installed if your building does not allow the construction of a column.

Overhead crane safety

The steel structure is strong and durable and the design has been optimized to reduce the stresses it exerts on your building.

Its operators can exert an optimal control over the load thanks to the control with an inverter of continuous speed along with the rolling.

An electric limit switch keeps you and your hoist protected from electrical overloads.

Since it minimizes the free height and the approach of the hook, it has a maximum space to perform other types of operations under your chain hoist crane. You can also install shock detection devices on the crane and in the car to further improve your safety.

Overhead Crane Types

Types of Overhead Cranes: The type of crane you have determines what your hoist will do for you. Some of the most common overhead crane types include:

• TOP RUNNING CRANE: The bridge moves atop a pair of rails mounted to the ceiling, allowing for heavy loads to be lifted and moved.
• UNDER RUNNING CRANE: The bridge travels along the bottom flange of two beams. Certain buildings’ construction might require this type of crane for your project.
• GANTRY CRANE: A single or double girder attaches to a pair of broad legs with wheels, enabling the crane to operate without being attached to the ceiling. These are popular cranes in shipbuilding.
• MONORAIL CRANE: The hoist attaches to a trolley on a single rail that follows a path around the facility in an oval or snaking path. This is effective for moving around a complex space.

Types of Hoist

Hoists are defined by their lifting medium, power, and suspension.

LIFTING MEDIUM: The lifting medium is the flexible material that connects the load hook to the overhead body of the hoist. It can be either a rope, metal cable, welded link chain, or roller load chain. Welded link chain, like an anchor chain, is a series of identical metal loops attached together to form a string. Roller load chain, like a bike chain, is made from alternating roller links and pin links to form a line that easily engages with a toothed sprocket.

POWER: Hoists can be powered manually, electrically, or pneumatically. Manual hoists use a pulley to multiply the operator’s pulling force. You can also use electricity or air power to actuate a hoist motor. Choose what’s easiest to access. Factories with many air tools might find air power more convenient.

SUSPENSION: The suspension method for a hoist depends on how it will be used. A stationary hook-mounted hoist is a simple solution when you only need to move a load straight up, such as from a truck to a trailer. Meanwhile, a hoist bolted to a beam will handle heavier loads. A hoist can be mounted to a trolley running along a beam or a rail, giving you the ability to lift up then across the facility. Gantry cranes give you three-dimensional motion. You can lift up, move the hoist along the gantry rail, then move the crane itself wherever you need it.

Double hoist overhead crane

Double hoist crane is a single girder crane with two Electric hoists for efficient material handling. Double hoist cranes have various designs such as double hoist Overhead Crane, and double hoist Gantry Crane.

Which double hoist crane is ideal for your application?

Double hoist crane

Double hoist crane is usually for indoor use, such as in the workshop, warehouse for handling and lifting small and medium tonnage items.

Generally, when choose or use double hoist crane, we usually consider it with one electric hoist, while in some specific situation, which need two electric hoists hoisting together, then the double hoist crane should be equipped with two electric hoists.

Bridge crane hoist

Overhead hoist and crane – bridge crane hoist: When the double hoist crane needs to be equipped with two electric hoists, the following items should be considered.

Two electric hoists capacity does not exceed the design capacity of the double hoist crane. That is, if you want to hang two 1Ton electric hoists, the double hoist crane lifting capacity should be 2ton or more.

If the double hoist crane total lifting capacity is greater than or equal to 1Ton, it needs the enterprise which has relevant qualifications to carry out the reconstruction.

Overhead crane anti collision system

Anti-collision device: If the two electric hoists use distance is far, it can directly use travel switch or photoelectric switch for the anti-collision setting.

• If the general use distance is near or sometimes use in the adjacent place two of the two electric hoists, you should pay attention to the closest position when installing during load and no load.
• If it is two-speed, it is best to limit the fast speed first, and then stop it (two tap positions).
• If the lifting item is long, it can be designed to operate with one switch, which can be operated simultaneously or individually.
• The power supply cable direction: on both ends of the single beam, respectively power supply to the two hoists, or power supply directly by safety slide wire.

Double hoist crane is used for efficient material handling. Double hoist cranes have various designs such as double hoist overhead crane, and double hoist gantry crane.

What is a crane hoist?

Difference Between Hoist and Crane:

• A crane incorporates the uses of other simple machines including the hoist to develop a more effective mechanical device that will make the moving of loads and objects easier and faster.
• A hoist is a device used for lifting and lowering loads while a crane is a device used for moving loads in different directions.
• A 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.
