Operating Experience with Friction-Type Mine Hoists at Geco Mines Limited
Friction-type hoists have been in operation at Geco Mines Limited since September, 1957. At the end of the year 1963, the skip hoist had handled n nearly 9 million tons of ore and waste. In March, 1962, with the deepening of the shaft, the hoisting depth was increased from 1,450 to 2,450 feet. Operating experience with the hoists, hoist and balance ropes, "rope treads and other related equipment is presented. The paper is intended to supplement an earlier one - "Heavy-Duty Friction Hoisting at Geco Mines," by W. M. Harvey (C.I.M. Transactions, Volume LXIII, 1960, pp. 193 - 197).
