Abstract
Disclosed is a pipe handling device, power-driven in three degrees of freedom, for manipulating pipe that is essentially vertically oriented. Specific embodiments described relate to racking and unracking drill pipe in a drilling derrick. A maneuverable arm, mounted on the derrick at an appropriate height, grips the pipe, lifts it and moves it to another location. A cable-assisted embodiment designed to handle heavy drill collars features a shock absorber assembly.
