How to Calculate the Size of a Mine Hoisting System
Geared engines are made with small cylinders, and the engine proper runs at a speed of 100 to 200 r. p. m. The gearing usually gives a reduction of 1/3 to 1/5 so that the drum revolves at a moderate speed. The small cylinders make the first cost lower than that of a direct-acting engine; but the gearing for large hoists is a serious objection.

Understanding The Operating Principle Of Hoists
Manual chain hoists convert a low force with a long travel input into a high force with a short travel output. This is the reason for their slow operation. They use multiple gears with varying numbers of teeth inside their lifting mechanism, which is activated by repeatedly pulling the hand chain. This principle is in charge of completing the ...

Blair multi-rope hoists Blair multi-rope hoists can be used as production or service hoists. Blair multi-rope hoists are also known as multi-rope drum hoists. They can use either one or two drums. A multi-rope drum hoist is similar to a drum hoist – but each drum uses two ropes to handle the load which, in turn, adds certain complications.

An overhead crane's hoist lifts and lowers a load by means of a drum or lift-wheel, in which chain or wire rope wraps around. Hoists can be defined by two main characteristics: The lifting medium (wire rope or chain) used to support the load. The power source (manual / hand-powered, electric-powered, or air-powered) used to perform the lift.
