Spring Return Hydraulic Bolt Tensioner
For industrial workflows where speed and consistency are non-negotiable, Tritorc's SLT Series Spring Return Hydraulic Bolt Tensioners are engineered to do both; deliver fast, repeatable bolt tensioning while ensuring uniform load distribution across every single joint. With a spring-return mechanism that eliminates manual resets, the SLT Series reduces fatigue and simplifies operations even in high-frequency, precision-critical bolting applications.
- Effortless piston reset via integrated spring return mechanism, enabling rapid tool removal and repositioning for seamless multi-bolt workflows with minimal manual input.
- Axial load application ensures zero torsion during tensioning, preventing thread galling, joint damage, or fastener fatigue caused by conventional bolting methods.
- Direct pressure-to-load conversion tightly regulates bolt elongation, delivering repeatable and uniform clamp force across all fastening points.
- Enclosed load cells and industrial-grade sealing prevent ingress of dust, moisture, and contaminants, ensuring stable, leak-free operation even in harsh plant environments.
- Interchangeable bridge system allows a single load cell to be used with multiple nut sizes, reducing tool inventory and improving operational flexibility.
- Precision-machined components and tight manufacturing tolerances ensure accurate alignment, long service life, and performance stability under high-pressure use.
- Suitable for bolt sizing from 20 to 100 mm.
- Max. Tensioning Load up to 3,200 KN.
