Technofast HydraNut hydraulically actuated nuts have earned the Australian Quarrying industry many thousands of dollars in reduced downtime and increased production.

Technofast HydraNut hydraulically actuated nuts are used on the half joint of gyratory crushers and the liners of jaw crushers to reduce the downtime during routine and emergency maintenance work.

Because the Technofast HydraNut hydraulically actuated nuts directly tensions the bolt, there is no damage to the abutting faces and the thread interfaces preventing nut seizure.

Technofast HydraNut hydraulically actuated nuts are a direct replacement for existing nuts and are simply fitted using a hydraulic pump.

A known load is applied to the bolts and therefore there is no danger of either over or under loading of the joint.

Any critical bolting application will benefit from use of Technofast HydraNut hydraulically actuated nuts, which has been used for many years to solve fastening problems.

Especially useful in confined spaces and where reaction points are difficult.

How do they work?

The Technofast HydraNut hydraulically actuated nut is screwed onto the bolt. The quick connect coupling allows pressure to be supplied by a hydraulic pump.

A calculated hydraulic force applied to a known piston area results in a precise load being applied to the bolt. The bolt is stretched and the lockring is then wound down to retain the load.

Benefits:

  • Fast
  • Accurate
  • Simple
  • Safe

The hydraulic pressure is released and the hose is disconnected. Technofast HydraNut hydraulically actuated nuts takes only minutes to tension any size of bolt.
