Multi-stage Hydraulic tensioner

High precision, even load distribution and unique performance

Slim and universally applicable series make the hydraulic tensioners PSD, PST and PSQ the optimal tool when it comes to using in confined spaces.

 

  • 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

Application examples 

  • Available in sizes M30 to M80 and power classes 471kN to 3587kN
  • 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
