Bolt Tensioning & Torqueing

  • Traditional methods of torque tightening large bolts and studs such as pounding on a flogging spanner, using an extension bar or even a mechanical torque wrench are inefficient and dangerous.
  • PTS Hydraulic Tensioners / Torqueing Tools are applying hydraulic force directly to the bolt and thus achieve accurate and uniform tension.
  • With Hydraulic Bolt Tensioning method hydraulic pressure is applied to normal bolt and nut assemblies using jacking tools (Load Cells). This causes the tool to extend and hence the bolt to stretch.
  • The nut is then run down and tightened manually and after releasing pressure, the jacking tools are removed.
