Breakout Clamps Overview:

The Clam Clamp is a unique design that doubles as a drill guide and a clamp. The front gate of the clamp swings open to give full access to the bore hole for rod loading. This gate when closed can be tightened by a hydraulic cylinder to give grip around the full circumference of the drill rod or casing. This has the advantage of being able to grip thin wall steel casing, even plastic and cardboard tubes can be held in place with this type of clamp whist auguring through the center. To grip different diameters of rod and casing a corresponding set of size reduction slips is used.
The clamp has a maximum internal diameter of 228mm (9") and is supplied with a set of slips that can be size modified to the customers needs.
An optional breakout cylinder is available to power a pipe wrench to break loose threaded tool joints.
