Pumping Ores Up Vertical Shafts

Hydraulic hoisting offers a number of attractive features over conventional hoisting methods: small shaft space requirements; great flexibility of layout, including pick-up or delivery of the material at points distant from the mine shaft; low investment and operating costs. However, limited practical experience with this type of hoisting dictates that careful design and, frequently, extensive testing be done by competent engineers before largescale installations are built.
