You mean DERRICK.
It is a framework erected over an oil well to allow drill tubes to be raised and lowered, or a simple crane having lifting tackle slung from a boom.

It's called a derreck. A derrick is a lifting device composed of one mast or pole which is hinged freely at the bottom. It is controlled by (usually 4) lines powered by some such means as man-hauling or motors, so that the pole can move in all 4 directions. A line runs up it and over its top with a hook on the end, like with a crane. It was commonly used in docks.
The device was named after Thomas Derrick, an English executioner from the Elizabethan era because of its resemblance of the frame from which a hangman's noose hangs.

Maybe you are thinking of Derrick crane, a combination of the derrick and the crane, having facility for hoisting and also for swinging the load horizontally?
