Excerpt from Steel Structures for Mines: Thesis for Degree of Civil Engineer
By head works is meant the structure placed get the mouth of the shaft that supports the sheaves, hoisting gear, etc. Where the sheaves are supported by a frame, the head works is called a Head Frame of Gallows Frame, and where the sheave is placed at the top of an enclosed structure, it is called a Shaft House or Rock House.
The Head Frame sometimes supports ore bins: while the Shaft House contains screens, bins, rock Crushers, etc. The first frames were usually built by ordinary carpenters who had no idea of the amount or direction of the stresses that members should be designed to take, and as a consequence many interesting structures are seen.
