Post Tension/Stressing Jack – 20 Ton, 8.5 in Stroke, 0.375 to 0.500 in Strand, 7575 psi Internal Pressure

The Power Team 20-Ton Post Tension/Stressing Jack is engineered for controlled tensioning of threaded rods, tendons, and anchorage systems in post-tensioning and structural stressing applications. Its high-strength hydraulic cylinder delivers uniform axial force across an 8.50 in stroke, enabling precise elongation of steel elements while maintaining concentric load alignment. The center-load configuration minimizes eccentric loading and ensures accurate force transfer during stressing operations in concrete construction and structural reinforcement systems.

Designed for repeatable performance in demanding jobsite conditions, the jack incorporates hardened load-bearing components, wear-resistant seals, and a precision-honed cylinder bore to maintain pressure integrity under cyclic loading. The robust steel housing resists deformation at full-rated capacity, while standardized hydraulic porting allows integration with 10,000 psi pumps and control systems. Its compact form factor and extended stroke make it suitable for bridge decks, slabs, beams, and anchorage zones requiring controlled, high-force tensioning.

Cylinder Movement

Extension (Tensioning): When pressurized hydraulic fluid is pumped into the cylinder, it forces the piston and attached piston rod outward in a linear motion to apply force. This is the action used for tensioning cables or anchor bolts in post-tensioning applications.
Retraction (Return): The SJ3010 is a single-acting cylinder with a spring return mechanism. To retract the piston, the hydraulic pressure is released, allowing an internal spring to push the piston rod back into the cylinder body.
