The chain hoist has either a lever to power the hoist or a loop of operating chain pulls through the block of the hoist which then powers the block that takes up the main lifting chain.

There are 3 things in a lever. They are load,fulcrum, effort. The place where the wheel is the fulcrum, the place where we put something is load,the place we hoist the wheelbarrow is the effort so it is a second class lever.
A lever is like a handle, whereas a pulley is chain or rope
They are lever pullers used to lift things up like firefighters, objects, etc. They are used by the firemen to get to the different floors of burning buildings, they also are used for towing and hoisting trucks out of their damaged position. They are used to tow cars out of traffic or from accidents. They are made of metal with a chain. Their purpose is to lift things up with out anyone having to use brute force.

A chain hoist uses gears to multiply force.A chain hoist is operated by hand. An operator pulls the light loop chain on the side of the chain hoist. This turns a gear mechanism inside the chain hoist housing to turn the chain pulley. When this pulley turns, it raises the heavy chain which usually has a hook on the end. By pulling the light chain loop, the manual hoist is actually able to increase the force that is being applied by the heavy chain. This is caused by the gear ratios inside the manual chain hoist. The mechanical work done by the operator is the same as the work done by the heavy lifting chain.

the lower hook
A chain is only as strong as it's weakest link.

There are many manufacturers online that sell electric chain hoists. Some of these retailers are: Hoosier Crane Service Company, Street Crane, and Custom Electric Panel. These are good places to start when one is thinking of buying an electric chain hoist.
Hi, I would like to know the real/original name of the 'chain hoist/pulley' I was taught 50 years ago when of doing O levels physics. I guess it was the inventor's name. Obviously we can still buy them but they only call them a chain hoist or pulley. thks john 23.11.10
Either the load would not lift cleanly, it might tilt or swing; or the hoist attachment mechanism (e.g. sling or chain) may fail. It will depend on the load, the hoist and the particular error in attachment.
