Patent ID: 10494816

Abstract:
A sheathing puller for use in a concrete post-tensioning system that includes at least one anchor assembly and a tension member comprising a cable and a sheath surrounding the cable, comprises a stationary coupler, a force applicator mechanically coupled to the stationary coupler, and a sheathing gripper mechanically coupled to the force applicator and configured to grip the sheath. Actuation of the force applicator may cause the sheathing gripper to grip the sheath and apply a longitudinal force thereto. The sheathing stationary coupler may be configured to engage the at least one anchor and the force applicator may be a pulley, screw, ratchet, bar clamp, pipe clamp, or screw clamp. Also disclosed is a method for mechanically coupling the stationary coupler to a fixed object, mechanically coupling the sheathing gripper to the sheath, and sliding the sheath along the tension member using the sheathing puller.
