A lever chain hoist works by using a lever to lift heavy loads. As the operator pulls the lever down, it engages a ratcheting mechanism that lifts the load. The chain attached to the hoist is used to support and lower the load.
Electric chain hoists use an electric motor to power a chain mechanism that lifts and lowers heavy loads. When the motor is activated, it drives the chain to lift the load, and when the motor is reversed, the load is lowered. These hoists are commonly used in industrial settings for their efficiency and precision in handling heavy materials.
An engine hoist would be a class 2 lever. The load (the engine being lifted) is between the effort (the force applied) and the fulcrum (the pivot point). This type of lever is useful for providing a mechanical advantage when lifting heavy objects.
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 pulley and a lever are both simple machines that help to make work easier by changing the direction or magnitude of a force. They both utilize the principle of mechanical advantage to multiply force or distance.
A ratchet lever hoist is a type of lifter that must be held from turning. It uses a ratcheting mechanism to lift loads by using a lever that needs to be engaged and held to control the lifting.
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.
Electric chain hoists use an electric motor to power a chain mechanism that lifts and lowers heavy loads. When the motor is activated, it drives the chain to lift the load, and when the motor is reversed, the load is lowered. These hoists are commonly used in industrial settings for their efficiency and precision in handling heavy materials.

A chain is only as strong as it's weakest link.
Lever 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
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.
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.
chain hoist and com-a-long
no it is a lever
