Abstract
A vehicle mounted drill rod holding and break-out device has a clamp jaw support reciprocatingly mounted in a housing. The housing is pivotally mounted on the vehicle to permit the free end of the housing, hence the clamp jaw support, to swing toward and away from the vehicle. A selectively extensible and retractable arm is pivotally mounted at one end on the outside of the housing. At its free end, the arm carries a pipe wrench, pivotally mounted on the arm in such a way that when the jaws of the pipe wrench engage a drill rod at the extended position of the arm and the arm is retracted, the drill rod is rotated to break a joint between the clamp and the wrench. The height of the housing is made adjustable to accommodate travel and working conditions.
