One of the methods to tighten joints using Bolts or Studs involves tensioning them using Hydraulic Bolt tensioners

1) The tool rests on a 'Bridge' and surrounds the fastener. It transfers the reaction forces using this bridge.
2) The tensioner uses the threaded portion of the fastener to 'pull' and lenghten the bolt using a loadcell and puller.
3) The space created between the nut and the surface can now be exploited.
4) In nut rotator and tommy bar can now be used to tighten the nut and close this gap to the calculated preload forces.


A Torsion free bolt elongation operation ensures that a gall damage free workspace is maintained. With Tritorc’s Top Side Hydraulic Bolt Tensioners (BTL series)
one can take on heavy duty tasks of bolt tensioning with the following advantages:

- Purely axial, tensile loading ensures no torsional stresses are introduced.
- Detachable and rotational bridge simplifies bolt tensioner positioning
- The applied load is controlled very accurately because it is directly proportional to the pressure applied to the tensioner.
