Purpose: to obtain a safe and optimally tight bolt connection.

Description: creating a torque in a safe way using (annually) calibrated hydraulic torque wrenches, this way coming very close to a specified bolt tension in a bolt connection. These torque wrenches are driven by pump groups of 700 bar (also annually calibrated), both electrically and pneumatically.

Execution: by our own specialised technicians. All our technicians have a safety passport and followed the following training courses:

• Training in setting torques and in tensioning
• Flange fitter
• Working with autonomous breathing apparatus
• Hitching on loads
• Rolling bridge operator
• Working with lifting platforms

Field of application: any place where critical bolt connections occur
