From equation 1, K=5000 lbs. X 2 +1500 X 2 lbs. + .01 X 8000 lbs. = 13,080 lbs., and ultimate strength of rope should be 7 X 13,080 =91,560 lbs., which would require a 1¼-inch- diameter flexible cast-steel rope, having an ultimate strength of 100,000 lbs., and weighing 2.45 lbs. per ft.

Hoister. Hoists include single-rope winding hoister, multi-rope friction hoister, Blair hoister (multi-rope winding hoist), and mine winch. Any type of hoister can be used for hoisting in a vertical shaft, but usually, single-rope winding hoister and mine winch are used for hoisting in inclined shaft.

Today's state-of-the-art technology for mine hoist brake systems is based on hydraulically operated disc brakes. ABB started this development in 1962 and has many years of experience in applying this technology to mine hoist systems. ABB's many developments and features on mine hoist disc brake systems have greatly improved the safety,

The accepted maximum value for emergency deceleration is 16.1 ft/s 2 (0.5g). Limiting emergency decelerations to rates less than 0.5g will minimize the possibility of injuring the passengers on the hoist. As shown in Table 1, the compound braking effort did not exceed 16.1 ft/s 2 (0.5g) for any possible condition.
