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.
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.
Hoist Cylinders are used by tractors, lifters, and cranes. They need special tools and skills to be repaired. You can not repair them at home. Take your hoist cylinder to a local mechanic.

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.
