Derrick

an apparatus for raising sunken ships, . The term is curiously derived from a hangman of that name frequently mentioned in Old Plays, as in the Bellman of London , 1616. “He rides circuit with the devil, and DERRICK must be his host, and Tyborne the inn at which he will light.” The term is now almost general for all cranes used in loading ships, or doing similar work of a heavy nature.
