A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a stiffleg derrick.
Much like a crane, a derrick is used for moving materials vertically and horizontally, comprised of a hoisting mechanism and pulleys or sheaves to create a mechanical advantage to lift large loads. Unlike a crane, a derrick usually has a vertical stationary mast extending from a base and a moveable boom.
