More on this story

Hoists are the component that makes it possible for overhead cranes, monorails, or work station cranes to lift heavy or bulky, freely suspended loads and are a critical part of lift cranes.

Its proper functioning is essential to guarantee the safety and efficiency of an operation. Whether manually, air or electrically powered, all hoists should be inspected routinely at a variety of intervals, including prior to use at the start of a shift, frequently, or periodically (annually for normal duty; semi-annually). for heavy duty; or quarterly for severe duty application).

Sometimes an inspection will reveal damage that can be repaired. In this case, the hoist must be removed from service and not used until the repair is complete. However, if the repair is not sufficient, the hoist will need to be replaced with a new one.

Crane hoist replacement period

To help hoist owners make that determination, here are four key signs that a hoist should be replaced:

Hoist problems

If a hoist perpetually fails to function as expected, for example, if it responds slowly or inconsistently to manual operation or to remote or hardwired controls, or if it requires multiple replacements of the same parts at frequent intervals, your Improper operation is causing costly problems, unplanned downtime and increasing the potential for an accident. Therefore, it must be replaced.

Hoist Parts accessories

Spare parts not available. Some hoists are so well maintained and have performed so well over a long period of operation that they are beyond the manufacturer’s ability to support them and replacement parts are no longer available.

Alternatively, a brand of hoist may have been purchased by another supplier who no longer supports that model. Or the brand may simply have been discontinued.

When service parts can no longer be reliably obtained, causing extended periods of downtime, the hoist must be replaced.

Spare parts prices for hoists

When a problem is identified, but the cost of repair (parts, service, or a combination of both) exceeds 50% to 60% of the cost of a replacement hoist, the operation should seriously consider replacing the hoist and invest in a new one.

A newer model will be supported by the manufacturer, have replacement parts more readily available, and will likely be backed by a warranty for a period of time, allowing it to offer a better value than the broken hoist.

Hoist Inspection Checklist

In addition to pre-shift inspections performed by the operator, in-house maintenance technicians, manufacturers’ service representatives, or an independent hoist inspection professional should perform more detailed frequent or periodic inspections.

These hoist evaluations can reveal a problem that is not visible to an operator.

The inspector will look for excessive component wear, cracks, distortion, warping, or other internal damage, or any other parts that show signs of possible failure. Based on that evaluation, the hoist may be deemed beyond reasonable repair and replacement is recommended.

Critical lifting examples

What is a critical failure of a Hoist or crane lift?

In the crane and rigging industry, a critical lift is a rigging activity where a comprehensive plan is needed to minimize the risk of crane failure or catastrophic loss.

As for the term “critical lift”, while there is no single universally accepted definition or industry standard used for categorization, there are a number of elements that are common to various rigging industry agencies and associations.

OSHA characterizes the definition as follows: a critical lift is one that

1. exceeds 75% of the rated capacity of the crane or derrick, or
2. requires the use of more than one crane or derrick.

The following are some of the items that appear most often in a critical survey, keeping in mind that specific projects have unique conditions that must be considered:

• Any lift that requires more than one crane
• Loads that exceed 75% of the rated capacity of a crane
• personnel lifting
• Cargo suspension above rigging personnel
• Loads that are not in sight of the crane operator
• Lots of exceptional value
• Cargoes that have the potential to become unstable during rigging

An I-beam trolley is a wheel mechanism from which a hoist is suspended to provide horizontal movement of the hoist along a beam or bridge rail.

Chain and lever hoists are most often used for applications that require a load to be lifted or suspended above the head.

However, when there are load bearing I-beams, securing the hoists to the beam can present a challenge, and that’s where clamps and trolleys come in.

W beams vs I beams

Let’s start with the basics: the horizontal pieces are known as flanges and the vertical piece is called the net. The flanges resist bending while the web assumes the cutting force.

An I-beam has tapered flanges with a narrower flange than most wide flange beams, making it a lighter construction material. A wide flange beam, with wider flanges and web than the I-beam, can support more weight, but this makes it heavier overall.

I-beam sizes standard

The standard I-Beam is named for its distinctive shape, similar to the capital letter “I”. The horizontal pieces are known as flanges and the vertical piece is called the web. This shape is very effective for carrying heavy loads without bending over.

I-beams are structural support materials that are used primarily for construction. Able to withstand excessive amounts of pressure, I-beams ensure structural integrity and stability.

The thickness of the I-beam will determine the type of work it is best suited for. It is important to consider the applied force, the weight supported, and the tension and compression.

The smaller sizes are typically used for jobs where the amount of pressure and weight will be minimal, while the thicker sizes of steel I-beams are used to support structures that support greater amounts of weight.

I beam hoist system

Know Your Tracks: The roads of your lift system in terms of overhead crane system roads are the lift roads.

In a lifting solution, the road surface, the part where the cart wheels roll and move, determines the smoothness of the lateral movements.

There are many other factors to consider when choosing a track for a lift system and there are a variety of tracks available, each of which is tailored to your budget and elevator environment.

Choosing which one is right for your operation is critical to the long-term use of the lift system and balances it against the cost of the system.

To clarify, if any beam or enclosure is used as part of a lifting system with a rolling surface, then in our industry, it is called a rail (although beams can be used for this purpose).

This is one of the many aspects of a lift that Acculift, after consultation with you and after site inspections, considers when designing a lift system for you.

Wireless remote control switch: Electric hoists safety with Industrial wireless remote controls switch

Electric hoists are an invaluable and essential component to a variety of industries including construction, manufacturing, warehousing, steel production, grain, logging, ship loading, and rail yards.

The reliance on hoists in these industries for loading, unloading, and moving heavy materials will remain for the foreseeable future.

This necessitates a continued focus on maintaining or improving operational safety and having the proper safety protocols in place.

One safety measure that is now widely adopted is the use of a wireless remote control system with a switch to control the electric hoist rather than using pendant or cab controls.

Electric Hoist with Wireless Remote Control

While these systems achieve a variety of process improvement and efficiency outcomes, a major driver of the adoption of remote control technology is the improvement of operator safety.

There are three primary ways that wireless remote control systems accomplish this.

-Minimizing the risk to operators from falling material or dropped loads.
-Reducing the risk of human error.
-Enabling the operator to more easily identify tripping hazards and pinch points.

Wireless electric hoist control minimizes the risk to operators caused by falling material or dropped loads.
..
An elevated risk of accidents due to falling materials is present unless the operator has the ability to be positioned at a safe distance from the load.

Reduced line of sight to the load, trip, slip hazards, mechanical failure, and operator competency are additional factors contributing to this risk.

With a wireless remote control switch, the operator is no longer tethered to the pendant and hence electric hoist, giving the flexibility to position themselves out of the danger zone, away from the hoist and its load.

As compared to the field of view when using a fixed pendant, wireless remote control with a switch also offers greater visibility and expanded line of sight to other operations and personnel on the ground.

This enables operators to avoid or alert other members of the work crew to an impending hazard and prevent it from happening.

Electric Hoist with remote control

Wireless controls are equipped to reduce human error.

One of the most important factors to minimize accidents is ensuring the electric hoist equipment is operated by qualified workers.

Having the proper certification and training on the equipment greatly improves the operator’s ability to prevent an accident.

Modern wireless remote controls come equipped with built-in safety features to supplement the operator’s own capability, adding another layer of prevention to the safety plan.

Examples of safety features in standard wireless remote control systems include:

• Ergonomic design to prevent inadvertent operations
• Easy to access and safe, machine stop switch
• Prevention of unexpected motions by using ‘push to operate’ buttons and bars’ or ‘double jog enable’ features
• Blocking of illogical combination and applying interlocks and restrictions on certain function combinations
• Haptic (vibration)
• LED and LCD indications and feedback
• RF and Infra-Red Close Start, RF Range limiting, and Infra-Red zoning
• Key Interlocks and Supervisory functions
• Wireless controls enable the operator to identify tripping hazards.

Wireless controls provide electric hoists operators with free mobility and improved line of sight.

These two factors make it easier for operators to identify potential tripping hazards and pinch points.

Operators can move at their own pace rather than the pace of the crane since they are no longer tethered to it.

Small Electric Hoist with Remote Control

Additionally, operators are no longer restricted by the range of movement of the pendant which gives them the flexibility to position themselves at a better vantage point with an improved line of sight, enabling them to more efficiently plan their movements and reducing the likelihood of tripping, slipping and crush points during the operation of the hoist.

Businesses and operators have adopted a wide variety of safety measures to keep hoist operators safe and preserve the essential use of cranes in these industries.

The use of wireless controls adds another layer of protection and will continue to be used by crane operators for many years to follow.

The mechanism used to raise and lower heavy loads to the desired height with comparatively little effort is called a lifting mechanism.

It is mainly operated with a system of pulleys and gears (either manually or mechanically) using electric power or fuel.

How does the hoist mechanism work?

They are generally used for loading and unloading very heavy materials that cannot be handled by one person and must be placed on transport trucks, ships, fixed spaces and many other places.

Chain block mechanism

The ability to move the load relies on the system of pulleys and cables, which can be fixed or mobile. This system varies the forces and the speed, needing to apply a force less than the load to be moved. The effort is also less than what we would need if the load were lifted freehand or with small hoists.

A specific overhead hoist configuration is generally defined by the lifting medium, operation, and suspension.

Hoist is the type of component used to transmit and cause vertical movement and includes cable, chain or synthetic strap, or rope.

Operation defines the type of power used to operate the lifting motion and includes manual power, electrical power, hydraulic power, or pneumatic power.

Suspension defines the type of mounting method used to suspend the hoist and includes hook, clevis, lug, trolley, platform, base, wall, or ceiling.

How to calculate hoist load capacity?

Determination of the required capacity

When selecting a manual, chain, or electric hoist, the rated capacity should be at least as high as the weight of the heaviest load to be lifted and no higher than the rated capacity of the bracket, monorail system, or another overhead structure from which the hoist will be raised.

In addition to the factors listed above for manual hoists, when determining the capacity requirement for an electric or air hoist, we must not only consider the weight of the heaviest load to be lifted, but also determine the average effective load.

Suspension kit for hoisting

Chain hoists can be suspended in a fixed location or can be mounted to a trolley by means of a top hook or mounting lug.

The cars can be rigid or articulated. Trolley travel can be simple (push type), manual geared or motor driven. See below for examples of typical chain hoist suspension types.

How does the lift system work?

When the corresponding button or joystick on the pendant or radio is activated, the hook moves vertically as long as certain conditions are met.

The product has a variety of built-in automatic safety features that, for example, prevent lifting overload, limit travel movements, or prevent all movements if the emergency stop button is activated.

Additionally, there may be operational limits (set by the owner or operator) that also limit movements under certain conditions.

Complete suspension kit for hoist

When a joystick or lift button is activated on the controller, a command is sent to the electrical panel.

The direction (up or down) of the hoist depends on which button or joystick is pressed. The speed of the hoist depends on the step that is activated.

The electrical panel controls the brake and the motor according to operator inputs, along with signals from sensors and safety devices.

When the motor is not being driven, the brake holds the motor in place, preventing it from turning inadvertently and the load from slipping down.

When a signal is transmitted from the controller, the electrical panel powers the motor and releases the brake.

• The motor drives the lifting mechanism which drives the lifting drum.
• The hoist mechanism reduces rotational speed and increases torque to lift the load.
• The wire rope winds or unwinds when the hoist drum rotates.
• The cable guide guides the steel cable to the correct groove on the drum.
• One end of the cable is fixed to the lifting drum with a cable clamp.
• The other end of the rope connects to the rope anchor.
• The cable passes around the cable pulleys to the cable anchor.
• The hook block raises and lowers as the cable is spooled on or off the hoist drum.

In normal use, when the raise or lower control on the controller is released, the control closes the main brake and brings the hoist to a gradual and controlled stop.

In emergency situations, the emergency stop button on the controller can be activated. This causes an instant stop of all movements by cutting power to the motors and applying the brakes.

When operating equipment and machinery, there is always a safety risk. Radio remote controls serve as a value-added solution to this underlying problem.

Radio remote controls are widely used in the construction, manufacturing, and equipment industries. Having a remote control completely changes the way machines are operated; the operator can easily control the device from a safe distance saving valuable person-hours.

Electric hoist with remote control

With a radio remote control, an operator can get the best possible line of sight when transporting or handling equipment. They can even manage operations from a remote location, allowing for one-person operation of the equipment.

Traditional working conditions required tireless efforts and involved risk to execute machine operations.

But radio remote control systems increase productivity and reduce overhead.

Initially, the remote controls were connected with cables, which still meant that the operator remained close by. Over time, remote control devices have been configured to be wireless and effective with greater ability and authority to control equipment.

Radio remote control devices are built with industrial-grade quality to enable a diverse workforce to eliminate the physical cost of manual labor. With remote control, operators can now work longer with less fatigue and complete projects on time.

emergency stop button

As an essential measure to avoid endangering the workplace or the surrounding area, a kill switch comes in handy.

There are cases where there are machine failures or things can go unplanned. To prevent the situation from escalating further, an emergency stop button acts as a safety mechanism. It helps keep the operation under control and stops all operations instantly in an emergency.

Improves operator safety

A radio remote control safely positions the operator at a safe distance from equipment or moving parts, falling dust, or debris, giving them the best vantage point.

Unrestricted operator mobility

With the remote control, the operator can change locations to get used to the working conditions and avoid losing sight of the machine. They can control the lifting and traveling functions and manipulate the movements of the hoist and the speed at which processes occur.
