Safety Measures When Using Electric Hoists

Correct operation method of limit switch

One of the most common mistakes made by electric chain hoist operators is the frequent use of limit switches. This can cause localized wear and damage to the limit switch. Limit switches are for emergency use and are not suitable for regular use. Regular use of them may cause the internal functioning of the hoist to be disrupted.

Someone is present during the lifting process

It is important to ensure that no one is standing under the load during lifting. Personnel around loads and equipment must wear necessary safety equipment such as helmets, gloves and safety shoes. This will reduce the risk of worker injury and load damage.

Correct positioning of the load

When operating an electric chain hoist, the position of the load must be checked. The load should be placed vertically under the hoist and the hoist should not be lifted at an angle as this may damage the hoist's internal components. Therefore, before lifting loads, make sure they are correctly positioned and connected to the hooks.

Never ride on the load

Operators or workers in manufacturing units should never ride on the load while lifting it. This adds extra stress to the machine and may cause failure. If this happens, not only are workers at risk of injury, but the machinery can also be damaged.

Avoid using a hoist that exceeds its lifting capacity

Every electric chain hoist has a specified safe working load capacity for lifting heavy objects, which means when operating an electric chain hoist it is important to ensure that the limit is not exceeded at any cost.

Factors to Consider When Choosing an Electric Hoist.

Load capacity

Different types of hoists have different load capacities. The rule of thumb is to make sure your load never exceeds the rated capacity at any time. Overloading will not only damage the equipment, but also endanger site safety.

Increase height

The lifting height refers to the maximum distance between the ground and the hook when the hoist is stationary. Consider the distance between the hook when it is raised and lowered. Also, remember to consider headroom, which is the distance between the hoist suspension and the hook when raised.

Environment and conditions

Lifting conditions play a vital role in guiding you as to which type of crane you should use. For example, air-operated hoists are better suited for hazardous, fast-paced environments because they are explosion-proof and have a 100% duty cycle. Before adding a crane to your cart, think carefully about where you will be using it.

Maintenance requirements

Before choosing which type of lifting equipment, make sure you are comfortable using that type of lifting equipment. If you don't know what to choose, discuss your options with your rigging hoist supplier.
