THE TORQUEMASTER BREAKOUT MACHINE. The Torquemaster is a self contained hydraulic make-up and breakout machine designed for fast, safe, and dependable maintenance of tools and motors in either workshop or drillsite locations. The basic machine consists of a bed complete with a fixed head- stock chuck, a moveable tailstock chuck that applies the torque, and a hydraulic console unit. TORQUE The torque is produced by two hydraulic cylinders which rotate the tailstock chuck through a 30 degree arc.  Breakout torque is greater than make-up torque at the same operating pressure due to the differential areas of the rod and head sides of the pistons. The Torquemaster requires no anchors or special mounting facilities since the torsional reactions are resisted by the base frame. SYNCHRONIZED GRIPPING FORCES The headstock and tailstock each contain six radially arranged heavy duty clamping cylinders.  Each piston rod is fitted with a replaceable tong die.  The hydraulic system is designed to move the cylinders in unison to positively center the workpiece regardless of weight or diameter.  The gripping force is in direct proportion to the applied torque, preventing damage to thin-walled components.
