Hoisting in Cars on Cages. Although hoisting in skips has largely replaced hoisting in cars at most modern metal mines, the latter practice is still employed and under some conditions has certain advantages that may outweigh the disadvantages. Thus in mines where two or more grades or classes of ore in addition to waste must be hoisted separately, it would …

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.
