Abstract
This report describes the development and underground operation of a semiautomatic, raise climber, human and supply hoist system designed for stope access in underground metal and nonmetal mines. Demonstrated capabilities of the system include a 4,000-lb payload capacity, control from the traveling cage and from up to five remote stations, operating in vertical or inclined raises 5 ft in diameter and up to 300 ft in length, and a travel speed of 50 ft/min. The system has the capability of operating in crooked raises because the conveyance climbs two stationary wire ropes suspended down the raise. The drive unit is electrically powered with power and control signals supplied to the drive unit through an armored cable also suspended down the raise. The system has been designed for portability, ease of installation, and minimum raise development. The system can be installed by two workers in five shifts. This report provides a detailed description of the hoist design and its demonstrated performance in two mine applications.
