How does a manual chain block work

 · How Does a Chain Block Work? A Chain Block contains a lifting chain, a hand chain, and a grabbing hook. Most chain blocks are operated using electricity, but manual chain blocks can be used too. First, the chain block needs to be connected to the load via the grabbing hook. Then when the hand chain is pulled, the chain tightens its grip on the. A manual chain hoist is a set of pulleys threaded with chain instead of rope to form a heavyweight block-and-tackle. When suspended from a suitable frame, a chain hoist can lift a heavy object, such as an engine block. The amount of weight the chain hoist can lift safely is clearly marked on the hoist and depends on the number of wheels, called. • Throw, drop or drag a chain block. • Allow oil or grease to come into contact with the brake. • Expose a chain block directly to the elements, water spray, steam etc without consulting the supplier.
