Abstract

A top drive for a drilling rig includes a top drive housing, a threaded element used in a drilling operation, the threaded element comprising a grooved surface, and a back-up wrench com prising a toothed surface configured to engage the grooved surface of the threaded element. The back-up wrench is suspended from the top drive housing. The back-up wrench is configured to be movable in relation to the top drive housing to selectively engage the threaded element.
