Hydraulic Bolt Tensioning

The miniBOOSTER intensifiers are commonly used for hydraulic bolt tensioning, offering precise tensioning of numerous large bolts.
The miniBOOSTER intensifier can be powered quickly and easily by tapping into the system hydraulics, supplying high flow and pressure up to 3,000 bar.

While torquing is a common method for fastening, bolt tensioning offers more control and reliability by directly measuring and applying tension to the bolt. Hydraulic bolt tensioning is a straightforward process, enabling precise tightening of multiple bolts simultaneously.
Bolt tensioning operations are conducted quietly at about 60 dBa, providing a conducive work environment for all users.

Well-proven applications:

Bolt tension on wind turbines
Bolt tension on cranes
Oil and gas
Offshore
