Hand chain hoist/Lever hoist

What is a lever hoist?

A lever hoist is a device used to lift heavy objects. It consists of a hoist and a mechanism for raising and lowering the load. The load is usually suspended from the hoist by means of a rope, chain, or wire rope. The most common type of lever hoist is one that uses a steel beam as its lifting mechanism. The beam is mounted on wheels or tracks so that it can move up and down freely while being controlled by ropes or chains attached to it at each end.

The lever hoist may be operated manually (by hand) or electrically, depending on its size and use. The operator pulls on one end of the rope or chain to raise the load, then releases it when he wants it to be lowered again.

Lever hoists are used in many industries around the world: mining, construction, manufacturing, agriculture and more!

How does a lever hoist work?

The lever hoist works because it allows an operator to exert more force than he or she would be able to with his or her own strength alone. The amount of force needed depends on how heavy the load is, but it can be far greater than what an individual with no mechanical assistance could manage.

A lever hoist typically consists of two main parts: a frame with a base and handles for an operator at each end; and one or more lifting devices attached to cables or chains which are wound around drums inside the frame. Each drum has teeth on its inner surface which engage with similar teeth on sprockets located at either end of each cable or chain looped around them. When an operator pulls down on one handle while pushing up on another handle (or vice versa), this causes one sprocket to rotate faster than its counterpart which rotates in the opposite direction causing one cable or chain looped around it to contract while its counterpart expands.
