Description

Image: Shaft No. 2, Quincy [Copper] Mine, Hancock, Mi., Detroit Publishing Co. no. 019057, c1906.

The Quincy Mine Hoist is the largest steam powered hoist ever manufactured, weighing more than 880 tons. It could lift 10 tons of ore at 16m/s, by serving the two incline skipways of Shaft No. 2, almost 2,900m long. The overhead winding drum has a lenght of 9m, divided into three 3m long sections. The cylindrical center section is 9m in diameter, both long end sections taper down to a 4.5m diameter. Wire hoisting ropes, which weight almost 27 tons, could be wound onto a small end of the cylindrical drum as the other rope unwound from the cylindrical section. Thus the weight of the ropes was in equilibrium and the engine did not have to lift it.

The hoist was powered by two cross-compound Corliss engines with cylinder bores of 81 and 152cm. The 167cm stroke drove the drum directly. With steam at 11kg/cm², 1.8 MW was developed at 34 revolutions per minute. In its first year, the new hoist pulled larger loads, faster, thus saving Quincy $16,080 in fuel bills. The hoist operated from 1920 to 1931.

Quincy mine is rather big, being nearly 3 km deep, with 98 levels and an enormous extension of 5 square kilometres. This Shaft No. 2 is only one of 20 shafts and numerous adits, which allow access to the mine. An adit into the hillside nerby, which is connected to the 7th level of the Quincy Mine, is used as an experimental mine by Michigan Technological University. The Mining Engineering program of the Department of Geological & Mining Engineering & Sciences conducts exercises here.
