Top Side Hydraulic Bolt Tensioners

At Tritorc, we recognise the realities of industrial bolting demands go beyond applying force. They involve achieving uniform tension, avoiding load imbalance, and ensuring consistent joint integrity under demanding conditions. Our topside hydraulic bolt tensioners are purpose-built to solve these challenges in every critical bolting cycle.
- By applying pure tensile force with no torsion, our tensioners avoid twist-induced damage that torque-based tools can cause.
- Achieve accurate load application in every cycle by maintaining a direct pressure-to-load relationship, ensuring consistent and repeatable bolt tension without manual variation.
- Withstand contaminant ingress and ensure consistent tension with our durable puller bars and sealed load cells, ideal for rugged industrial applications.
- Precision machining and composite seal kits eliminates stud misalignment and prevent pressure losses or fluid leaks during operation.
- Attain rapid piston reset, speeding up repeated tension cycles through our automatic or spring-return configurations.
- Handles bolt sizes from 16-150 mm.
- Delivers a Max. Tensioning Load up to 5406 KN.

Why Use Tritorc's Low Profile Hydraulic Torque Wrench
Special seal kit
With a lower coefficient of friction the Top Side mechanism retracts the piston faster. The load transfer factor is calculable, helping to give the correct residual load.
