a lifting device that uses a chain and pulley system to lift and lower heavy loads
A chain block is a mechanical lifting device used to raise or lower heavy loads using a chain. It consists of a chain, a block with gears, and a hook to attach the load. By pulling on the chain, the user activates the gear mechanism, which lifts the load. Chain blocks are commonly used in construction, warehouses, and workshops for lifting heavy materials or equipment. They are reliable, easy to operate, and can handle various lifting tasks, especially in areas where space is limited.
