Superbolt var de første i verden, der revolutionerede møtrikker med Multi-Jackbolt tensioning teknologi. Siden har teknologien bevist sit værd i titusinder af vellykkede installationer, og vi fortsætter med at udvikle en lang række løsninger med udgangspunkt i Multi-Jackbolt teknologien.

Multi-Jackbolt Tensioners

Superbolt tensioners offer you simple and cost-effective tightening of large size bolts. Your joints can be tightened with high accuracy without requiring specialized skills or heavy tooling.

A wide range of tensioners is available in the standard series, as well as an unlimited capacity to create special designs to meet your unique needs.

 

The standard series includes nut-style and bolt-style tensioners.

Bolting Made Simple

Superbolt multi-jackbolt tensioners take high preload requirements and break them down into manageable torques using the jackbolts threaded through the nut body. They remain easy to install, even on larger sizes, compared to standard hex bolts.

 

Advantages

  • Quick and easy installation and removal
  • Only hand tools required
  • Safe method for installation
  • Fits in restricted areas
  • Profitable life-cycle cost
  • Reliable operation
  • Simple maintenance procedure
