A derrick consisting of a spar, mast, or a-frame set on end and usually supported at the bottom by two horizontal spars or sills, with inclined beams running from end of sills to mast to form a triangle.

The hoisting unit is generally not an integral part of this device but may be located any distance from the derrick.
