Hoisting methods There are basically only two hoisting methods, plus some modifications, in use today: drum and friction. The drum hoist stores the rope not extended in the shaft. The friction-sheave hoist passes the rope (or ropes) over the drive wheel but does not store it. (Sometimes the method is called Koepe hoisting, after its inventor.)
