Abstract
A method for making-up or breaking-out a pair of tubulars using a tong assembly of a drilling rig. The method uses a pair of chain assemblies connected to hydraulic chain cylinders, a first jaw connected to a first arm for supporting a first tubular, a second jaw connected to a break-out body between the break-out body and the second chain cylinder, and a make out break-out cylinder to push the chain cylinders in a make-up rotation or a break-out rotation allowing the method to provide changes of direction without changing tong assembly configuration or position.
