Multi Stage Hydraulic Bolt Tensioners

Engineered to meet the challenges of critical industrial bolting applications, Tritorc's Multi Stage Hydraulic Bolt Tensioners are ideal for environments requiring higher load capacities or tighter access than conventional tensioners can handle. Our MST series units expand the range of solutions and provide effective tensioning end results.
- Delivering concentrated hydraulic tension directly along the stud axis, our MST series eliminates the risk of twist-induced thread or galling damage.
- Achieve high repeatability and multi-bolt operations, shortening downtime through rapid tool reset translation which propels the piston back to start position instantly after pressure is released.
- Experience direct pressure-to-load translation and automated piston advancement that tightly regulates bolt elongation, ensuring every cycle yields a reliably uniform clamping force.
- Our high-precision machining and tightly controlled manufacturing tolerances delivers flawless tensioner to stud alignment ensuring pressure-stable and leak-free performance.
- Sealed load cells enclosing enhanced puller bars blocks out dust, moisture, and abrasive conditions ensuring reliable performance in harsh, vibration-prone environments.
- Suitable for Bolt sizing from 30 to 48 mm Dia.
- Max. Tensioning Load up to 1,231 KN.

Why Use Tritorc's Low Profile Hydraulic Torque Wrench
Over Stroke Alarming Mark
The End cap is designed to bear high back pressure. This allows the piston operation to be smooth and the forward force is applied properly. A red marked line denotes an over-stroke, warning the user to stop the hydraulic pressure
