Chain blocks

A chain block is a manual lifting tool that uses a series of gears and a chain to lift heavy loads. It is typically made of steel or aluminium, and it has a hand crank that is used to turn the gears. The chain block is attached to the load with a hook, and it can be used to lift the load up to a certain height. If you need to lift a heavy load, a chain block is a valuable tool. They are safe, efficient, and easy to use.
