Abstract

A tool carrier, which is also known as a top drive or a power swivel, for a well operation rig includes link arms coupled between the rotating hook assembly and the lower pipe gripping structure, the link arms each secured to the rotating hook assembly by a first rigid connection and secured to the lower pipe gripping structure by a second rigid connection such that the link arms can extend along well center even when operating in slant. Another tool carrier includes a hinge between the mast and the main housing. The hinge permits the tool carrier to be moved into a more central position when folded onto the rig chassis for transport.
