Explain what happens in the winding house of a mine
Part 1: The winch or hoist is in a winding house. This part of the system is used to wind or unwind the steel cable. The hoist is attached to a motor and a control system. The mine cage and the skips are lowered into the mine when a steel cable unwinds from the winch. The mine cage and skips are raised when the steel cable winds up again.
