Slim and universally applicable series make the hydraulic tensioners PSD, PST and PSQ the optimal tool when it comes to using in confined spaces.
Thanks to their multi-stage design, the tension cylinders provide the required tensile forces with a minimal diameter. They are ideal for use in confined lateral installation
spaces. The preload force can be precisely adjusted, and the modular design allows for optimal customisation to suit your specific bolting application.
- Optical over stroke indicator
- Hydraulic unit can be aligned/rotated/around 360°
- Avoid damage due to spring-assisted coupling between the rotating sleeve and hexagon nut
- Removable handle and carrying strap for maximum comfort and safety during transport and use
- suitable for the use of parallel-connected tensioners
- Anti-rotation between tension nut and tension bolt using feather key
SECURITY INDICATOR – GREEN: A sufficient bolt insertion; depth has been reached RED: Maximum stroke of the draw bolt has been completed
The removable handle provides optimum grip and protects the hose connections from damage
Optimum handling: easy alignment thanks to rotatable support, regardless of the bolt arrangement
- Available in sizes M30 to M80 and power classes 470kN to 4200kN
- Case counter: definition of the maintenance time
- Optimal geometry of the support surface
- Maximum safety thanks to “fail-safe piston clamping”: the end stop limits the extension of the piston (even under maximum load).
- Highest speed: fast working due to automatic piston reset.
- Long-lasting and sustainable due to connection of cylinder tubes via bayonet lock: Components are easy to disassemble and replace for servicing
