Reaction Suspension System – HTS was designed specifically for hand tool applications. This suspension includes a linear motion device that provides vertical travel for positioning and torque reaction of the tool. Equipped with a WP Balancer, the system provides a lift assist for the operator, offering low handling forces and smooth movement. The balancer can be set to hold at a balanced position along the vertical travel or set to raise to the upper travel position. Torque can be applied in a horizontal, vertical or angular tightening orientation.
