head sheave
The head sheave is a fixed pulley at the top of the mine shaft frame that adjusts the direction of the wire rope. Its function is to support the wire rope connecting the hoist drum and the hoist container, and to guide the wire rope in a different direction. There are three types of sky sheaves: floating sky sheave, fixed sky sheave above the shaft, and fixed sky sheave for drilling and underground. The types of wire ropes that go with the sky sheave include phosphate-coated wire rope, galvanized wire rope, or smooth wire rope.
