A derrick is a lifting system composed at minimum of one guyed mast, as in a gin pole, which may also be articulated over a load by means of adjusting its guys. Most derricks have at least two components, both a guyed mast or self-supporting tower, and a growth hinged at its base to provide articulation, as in a stiffleg derrick.

The most basic type of derrick is controlled by three or 4 lines connected to the pinnacle of the mast, which permit it both to cross laterally and cant up and down. To lift a load, a separate line runs up and over the mast with a hook on its free end, as with a crane.

Forms of derricks are commonly discovered aboard ships and at docking facilities. Some massive derricks are installed on dedicated vessels, and known as floating derricks[3] and sheerlegs.

The time period derrick is also utilized to the framework helping a drilling equipment in an oil rig.

The derrick derives its identify from a kind of gallows named after Thomas Derrick, an Elizabethan generation English executioner.
