To ensure best possible safety of our bolt tensioning cylinder, we provide safety handles, cycle counter and a fracture device. As per client's requirements, standard and large-scale cylinders can be provided. Some of its application areas are in mounting of wind turbine & its inner tower flange, on ladle turret, and tower crane connection.

Bolting Process of Cylinder

  • A hand torque wrench can be used for threading the cylinder onto bolt
  • A high pressure pump is used for applying the desired pressure
  • This results in elongation of bolt, which is free from friction and torsion
  • Upon reaching the required pressure, wrench is used to tighten the nut and hence achieve controlled torque output.
