What is a chain hoist ?

 

A chain hoist is a mechanical device used for lifting heavy loads of objects and equipment. It is made with a pulley, which is held together by a closed chain. The closed chain forms a loop, which makes it easy to be pulled by hand.

There are several large and small pulleys located throughout a chain hoist. There is one large and one small pulley are situated on the same axle, as well as a also a mobile pulley that holds the load in place.

For the load to be raised with the chain hoist, the closed chain has to be pulled. When it is pulled, the large pulley draws in more chain than what is released by the smaller side. From here, the lifting process begins.

There are three types of chain hoists: air, manual, and electric. The manual one and the air one are designed with reduction gears, hook pivots, and swivels. Suspended by a top hook, or by a push or geared trolley, these devices move objects slowly and carefully while making height adjustments. The attached load is well secured so it can be left fixed without requiring a great deal of supervision.

The electric chain hoist, on the other hand, is generally used for lifting heavy-duty industrial loads. It allows the user to pull from the side as well as vertically.
