JKM-3.25*4(III) multi-rope mine hoist

Model: JKM-3.25*4(III)

JKM/JKMD series mine hoists are multi-rope friction hoisting equipment, designed for deep wells (up to2,000 meters deep) in coal mines, metal mines and non-metallic mines, and are mainly used for mineral hoisting, personnel lifting and equipment transportation in vertical shafts.Its core principle is to drive the container movement through the friction between the wire rope and the friction wheel pad. It has the characteristics of large lifting capacity, small wire rope diameter and compact friction wheel size. It is divided into two types: well tower type (JKM series) and floor type (JKMD series). The machine room is located on the top tower or ground of the shaft.

Lifting Capacity: 48 Tons (Vertical) / 48–96 Tons (Inclined)
Reel Dimensions: 3.25m Diameter
Wire Rope: 32mm Diameter
Lifting Speed: 15m/s
Number of wire ropes: 4
