Power Seating Jacks

A post-tension jack that uses hydraulic force to seat the wedges, rather than relying on a spring. That gives the operator more control over how the wedge sets and more precision in the stressing itself. It is the workhorse jack for stressing post-tension cable.

Control and weight. Hydraulic seating is more precise and more consistent than a spring, and power seating jacks weigh less than spring-loaded models. Lower weight matters for crew mobility and safety, particularly in elevated work where the jack has to be carried and supported by hand.

The cylinder seals, the nose piece, the grippers and the gripper retainer plates. Grippers bite the strand every cycle, so they are consumable. Retainer plates are exposed and take knocks. Gripper blocks and handles normally last unless something damages them. Call 832-671-0978 with the model and we will tell you what we have on the shelf and what we can source.

There is no single interval, because it depends entirely on cycles and conditions. The practical answer is that you service it when performance changes: pressure drops off, seating gets inconsistent, or you see a leak. Post-tension work is high-cycle and hard on equipment, so a jack running every day earns attention sooner than one that comes out occasionally.
