Headframe

 

a structure that houses mine-shaft hoisting equipment. Headframes are differentiated according to the materials from which they are made (wood, metal, reinforced-concrete, or mixed types) and the number of hoisting machines (one, two, or three) and their arrangement relative to the shaft (parallel to the shaft, at an angle, or in the headframe). Metal and wooden headframes, usually of a tent-shaped system, are a three-dimensional construction in the form of a truncated pyramid with sloping walls. Reinforced-concrete headframes are usually erected in the form of a tower 80-100 m high, in which the hoisting machinery is located.
