en.wikipedia.org › wiki › Hoist_(device)Hoist (device) – Wikipedia A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The most familiar form is an elevator, the car of which is raised and lowered by a hoist mechanism. toolsdoctor.com › how-does-a-chain-hoist-workHow does a chain hoist work & how to properly use it Mar 15, 2022 · A chain hoist, sometimes known as a chain block, is a lifting mechanism for heavy loads. When lifting or lowering heavy loads, this mechanism uses a chain wrapped around two wheels. If you pull the chain from one side, it will start to wind around the wheels and lift the attached heavy item on the other side.

This chain wheel is attached to a short driveshaft and gear system. It multiplies the input to drive a slow-moving high-torque gear for hoisting or lowering the load. www.youtube.com › watchHow it Works The Chain Hoist – YouTube Jul 5, 2010 · How it Works The Chain Hoist www.worlifts.co.uk › blog › how-a-chain-hoist-worksHow a chain hoist works – Worlifts Design Inside the chain hoist housing are two gears. One is smaller than the other. Most chain hoists use a 20cm and 25cm gear. The two gears are attached, so when one moves, the other moves. The chain is looped over the smaller gear, and then hangs down in a loop (the loop you pull on).
