A Chain Block (also known as a hand chain pulley hoist) is a mechanism used to lift and lower heavy loads using a chain. Chain blocks contain two wheels in 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 rope or chain via a hook. Chain block is a hand operated device that is able to lift or lower loads. Two type of chain blocks, DS and DH, are available with different capacities and net weight. Both series can be provided in stainless steel or explosion proof version.
