Electric Chain Hoists-Various Tasks Helping Device

By: sanoj

An Electric Chain Hoists are electronic devices, used to lift heavy and bulky objects. There lies an electric motor in the hoist which drives a set of gears,in between the gears there lies a chain. As the motor gets activated there is a turn in the gears and depending up on the direction of the motor, the chain gets pulled up or lowered down.
These hoists are used to lift from a smaller object to an extremely heavy object. They have the capacity of lifting any kind of object, it can be a car engine or a steal beam it can lift them all. They can be used at the places like building sites, warehouses, docks, and can even be used to lower chandeliers so its an instrument used for varied purposes. These hoists are available in varied capacity from 125kg to10000kgs.
They help in performing the task faster and conveniently. These hoist are quite easy to use than their manual counterpart. Depending up on the weight of the load to be lifted these Electric Chain Hoists come in various sizes so as to meet the demand and complete the task without any difficulty.
Working of the Electric Chain hoists..
At first the hoist is attached to a structure, like mobile gantry or jib crane or to a solidly anchored hook so as to provide a strong load bearing structure to the hoist. After this with the help of a power driven control pad the hoist's chain system can be lowered, then the choice of the item which is to be lifted is made and then the hoist is either fixed directly to the weight if suitable, but to insure a balanced lift a further chain sling is used as it can be placed around the load about it's center of gravity. Then the sling is attached to the Electric chain hoists' chain hook and the load is ready to be lifted , the motion of the hoist should slow in the beginning until your are sure of its stability.
Safety Concerns
These hoists should always be used according to the safety standards. There should never be hoist near the area where people are working so a special care should be taken that no one should be allowed to work under or near the hoist weight. Most of the hoists come up with inbuilt safety features, to avoid the disengagement of the load hooks will have the safety catches. To avoid the overloading of the equipment there is a clutch system in the hoist which slips at a present torque. Also in some electric hoist there is a switch mechanism which helps in engaging the chain mechanically if there is some overloading.
Hence, this hoist is a cost effective equipment to lift loads of any size and weight but importance should also be given to the safety regulations so as to make most of it.
