Nord-Lock Group About Boltight Products Typhoon Tensioners

Boltight has been at the forefront of hydraulic bolt tensioning for over a decade. Our tensioning tools provide fast, accurate and safe solutions to tighten and loosen multiple bolts simultaneously.

Typhoon Tensioners

Boltight's Typhoon range of bolt tensioners offer a high-load, low profile solution for space-restricted applications demanding high and accurate preloads, such as wind turbines.

The tensioners exert a high load with both the multi-stage, ideal for radial obstruction applications and the single stage, for vertical obstruction applications.

Features

  • Standard (M24 to M64 held in stock)
  • Specials are as common as standards
  • Predominantly Wind Turbine application (extensive data base held)
  • Other typical applications:
    • Crane slew rings
    • Tunnel boring machines
    • Gas turbine casings

Advantages

  • Designed for high loads – up to 95% yield stress for 10.9 bolts
  • Spring loaded gear drive for nut rotation
  • Automatic piston retraction and positive stop facility
  • Single stage design for vertical obstruction applications
  • Multi stage design for radial obstruction applications
  • Suitable for height restricted areas
  • Durable coating on all components
  • Joint misalignment compensation features
  • Internal fail safe mechanism
