Safe Use of Electric Chain Hoists

• Store and handle electric chain hoists correctly.
• Inspect the hoist and accessories before use and before placing into storage.
• For top hook suspension, use hooks that are fitted with safety catches or mouse the hook and ensure the support fits freely into the seat of the hook.
• For trolley suspension, ensure the trolley is correctly set for the beam width.
• Check that the bottom hook will reach its lowest point without running the chain or rope fully out.
• Raise the load just clear then halt the lift to ensure the integrity of the hoist before continuing with the lift. If the hoist has more than one speed, start in the slow speed.

• Expose power operated hoists to chemicals, particularly acids, without consulting the supplier.
• Expose power operated hoists directly to the elements, water spray, steam etc without consulting the supplier.
• Replace the load chain or rope with a longer one without consulting the supplier.
• Use the load chain or rope to form a sling.
• Change motions without first allowing the motor to stop.
• Allow persons to ride on power operated hoists.

Selecting the Correct Hoist
Power operated hoists are available in a range of capacities, designs and suspensions with electric or pneumatic power options. Select the hoist to be used and plan the lift taking the following into account:
Type of hoist - chain, wire rope - electric, pneumatic - class of use - capacity and range of lift etc.
Type of suspension - hook, trolley, fixed.
Speeds and control - single speed, dual speed - pendant push button, pull cord, remote etc.
Power operated hoists are designed for vertical lifting only.
Consult the supplier if the hoist is to be used in areas of high risk, exposed to the elements, water, steam etc, with hazardous substances, eg acids or chemicals, or subjected to extremes of temperature.

Storing and Handling Power Operated Hoists
Never return damaged hoists to storage. They should be dry, clean and protected from corrosion.
In the case of hoists used for temporary applications, store them on a purpose made rack or suspended from their top suspension fitting. Trailing cables, pendants etc may be 
removed, identified and stored separately to prevent loss or damage whilst in store.
In the case of hoists left in situ, park the hoist in a suitable position so that it is protected from damage and does not present a danger. Raise the bottom hook so that it is not a danger to persons or liable to become accidentally engaged.
Isolate the power supply.

Installing and Commissioning
Follow the specific instructions for installation and commissioning issued by the supplier and the general requirements given overleaf. Ensure the controls work in the correct direction and that motion limits are set and operate correctly. If the hoist fails to operate correctly contact the supplier.

Using Power Operated Hoists Safely
Do not use defective hoists, slings or accessories.

Check the slinging arrangement, that the hoist is safely rigged, that the chain or rope is not twisted and that the load is free to move.

Raise the load just clear, halt the lift to ensure the integrity of the hoist, slinging arrangement etc. Always commence lifting in the slow speed. Avoid unnecessary inching of the load.
Check the travel path is clear and that you have a clear view so as to avoid accidental hook engagement or collision. Follow any particular site safety rules applicable to the movement of suspended loads.

Keep fingers, toes etc clear when lowering loads.

In-service Inspection and Maintenance
Follow the specific instructions for maintenance issued by the supplier. These should be incorporated into the site maintenance programme observing any particular needs due to the site or working conditions.
Regularly inspect the hoist and, in the event of the following defects, refer the hoist to a Competent Person for thorough examination: operational faults; hoist will not lift; slips back; motion commands reversed; over-runs when command released; wear; damage to trolley, hooks and fittings; damaged, worn or corroded chain or rope; other visible defects.

Electric Chain Hoist

An electric chain hoist is a mechanical lifting device used to raise and lower heavy loads vertically. It is commonly used in industrial and commercial settings to facilitate the movement of materials and equipment. Electric chain hoists are known for their efficiency, durability, and ease of operation. Here are some key features and components of an electric chain hoist:

  • Chain: The chain is a crucial component of the hoist and is used to lift and lower the load. It is typically made of high-strength alloy steel and is available in various sizes and lengths to match the lifting capacity of the hoist.
  • Hoist Motor: The electric chain hoist is powered by an electric motor that provides the necessary force to lift the load. These motors are designed for heavy-duty operation and can handle a wide range of loads.
  • Controls: Electric chain hoists come with control mechanisms that allow operators to raise, lower, and sometimes move the load horizontally. Control options include pendant controls, push-button controls, or remote controls, depending on the specific model.
  • Gearbox: The gearbox is responsible for transmitting power from the motor to the chain drum, which in turn lifts or lowers the load. It ensures smooth and controlled movement.
  • Chain Drum: The chain drum is a cylindrical component around which the lifting chain is wound. When the motor rotates the drum, the chain is either wound up or paid out to raise or lower the load.
  • Safety Features: Safety is a paramount concern with electric chain hoists. They often come equipped with safety features such as overload protection to prevent lifting loads beyond the rated capacity, limit switches to prevent over-travel, and emergency stop buttons for immediate shutdown in case of an emergency.
  • Lifting Capacity: Electric chain hoists are available in a wide range of lifting capacities, from a few hundred pounds to several tons. The specific capacity should match the requirements of the application.
  • Mounting Options: Electric chain hoists can be mounted in various ways, including fixed mounting on a beam, trolley mounting for horizontal movement, or as part of a more complex crane system.
  • Duty Cycle: The duty cycle of an electric chain hoist refers to the amount of time it can operate continuously without overheating. Different hoists are designed for different duty cycles, with some suitable for continuous use and others for intermittent use.
  • Voltage and Power Supply: Electric chain hoists are available in different voltage configurations to match the electrical infrastructure of the facility where they will be used.

Electric chain hoists are widely used in manufacturing, construction, warehouses, and various other industries where heavy lifting is required. When selecting an electric chain hoist, it's important to consider factors such as lifting capacity, control options, safety features, and compatibility with the intended application. Proper training and adherence to safety guidelines are essential when operating electric chain hoists to ensure safe and efficient material handling.

How to choose a right electric chain hoist?

  • Load weight- The load to be lifted determines what hoists you have to buy.
  • Lifting speed- You need to calibrate it for the successful loading and unloading process of materials.
  • Your work environment- Some factory environments may cause abrasion for your machinery. For instance, under a very high-temperature condition, your hoist can start malfunctioning. Similarly, very low-temperature level results in cracks and freezing issues of internal parts. The frequent fluctuation of temperature is another risk of your system, and you can face the risk of short circuits.
  • Height of your lift- You want to lift your load up to a height. This factor is important to choose the right hoist model. There is a chain container with electric hoist. The increased height denotes a longer chain and a bigger container. However, too much large containers can turn out to be a barrier to your load lifting process.
  • The duty cycle- It indicates the duration for which you will use the hoist. This factor has a relation to longevity. Thus, the duty cycle length is one of the important things, as your system has to disperse heat from motors.
