Each of these components requires extensive design considerations. For further information regarding shafts please see the article Shaft construction. en.wikipedia.org › wiki › Hoist_(mining)Hoist (mining) – Wikipedia Advantages New friction hoists are less expensive than new drum hoists, and the lead time for delivery may be shorter as there is more competition for manufacturing. Multi-rope friction hoists have a larger lift capacity than a drum hoist.

For deeper mines, drum hoists of various designs are a common solution. Drum hoists are also often used in shallow mines and for transporting personnel and equipment. Depth library.e.abb.com › publicTypes of mine hoists – ABB 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. Two ropes carrying the load provides for a higher payload (but not double the payload). www.teufelberger.com › mining › blair-hoistBlair hoist | Teufelberger Single layer drum hoist .

In South Africa, installation of the second of two large Blair multi-rope hoists for a gold producer is under way. At that site, single-wind depths of 3,000 m and 102-mt compartment loads represent potentially the largest production reference base developed to date by the company. hoist systems – ABB”>search.abb.com › library › DownloadMine hoist systems – ABB
hoists, or for mines using very large Blair multi-rope hoists where the peak power can be in ex-cess of 20 MW. ABB’s PSR system works on the concept of inertial energy. The inertial energy of a decelerating mine hoist is captured, stored and reused to limit the peak power of the accelerating mine hoist. Auxiliary hoisting equipment and shaft
