Hoists are mechanical devices that use relatively small amounts of force to lift, lower, and move heavy loads. Manual hoists work by transferring a force exerted by hand across a series of gears that concentrate it into a force great enough to lift the designated load. The lifting mechanism consists of a pulley with a chain or cord and large wheel, or a ratchet lever attached to a large wheel; a drive shaft; gear set; sprocket wheel threaded with a load chain; and a lifting hook.

The pulley or ratchet turns the drive shaft, which engages the gears; the gears interact to rotate the sprocket wheel and load chain, which pulls the hook up to lift the load. When the force used to turn the large wheel reaches the smaller sprocket wheel, it has become concentrated enough to lift the load. Friction disk brakes called Weston-style brakes are attached to the large wheel. These brakes hold the load in place while the operator's hands are released to make the next pull, secure the load once it has been lifted, and control the descent of load as it is lowered.
