CHAIN PULLEY

It is a pulley with depressions in the periphery of its wheel, or projections from it, made to fit the links of a chain. The desired capacity chain pulley is hooked at the centre to lift heavy load for loading and unloading at site. It is a mechanism used to lift and lower heavy loads using a chain. Chain blocks contain two wheels which the chain is wound around. When the chain is pulled, it winds around the wheels and begins to lift the item that is attached to the chain via a hook.
