Features


An hydraulic bolt tensioner with an auto retract mechanism would help with rapid setup of a bolt tensioning operation. This tool would reduce the amount of time required to remove tensioner and have additional advantages such as

  • Spring return mechanism ensures piston retraction of the tensioner, ensuring quick tensioning cycles.
  • Built-in Stroke limit valve safely prevents over stroke.
  • Avoid torsional stresses and galling on the nut seat found in torque wrenches.
  • Simultaneous tensioning of multiple bolts
