Friction hoists, also known as Koepe winders, can be used either for production or service purposes for the . transportation of material, equipment and personnel. They are suitable at depths of 150 2000 m, although
2017-1-1 Abstract. The hoisting system is essential for the transportation of equipment, personnel, mined ore and thus for the productivity of the mine. It consists of various components in which there are winders, ropes and electric motors. The safety and reliability of the hoist depends on its design, therefore proper and accurate design of a hoist is
2019-6-28 This article was prepared for the Queen's University Mine Design Wiki Page.. The following article is regarding the design of underground mine hoisting systems Mine hoisting systems are comprised of five major components: hoists, conveyances, wire ropes, shafts, and headframes. Each of these components requires extensive design considerations.

A common trend in underground mining is that mines are going deeper and payloads are increasing. Extracting minerals from below the earth takes big, and very specialised, hoisting gear. The choice of most productive and sustainable hoist system depends on depth, needed capacity and loads.

2021-2-15 Mining Ltd) discovered the zinc/ copper ore deposit with reserves of over 30 million tonnes in 1958. Open-cast mining started in 1962 and continued until 1976, when it was switched over to underground mining. ABB supplied the mine hoist system. The shaft depth was then only about 660 metres but was later extended to 1,000 metres.
2021-2-16 A double hoist is suitable at any depth up to the current maximum assumed hoist depth (due to the . technical limitations of hoist rope) of 2000 m. Normally, one drum raises a full load, while the other drum lowers an empty load. A double drum hoist normally costs more than the friction hoist equivalent
