Ensure a more reliable operation of wind turbines

Achieving the correct bolt pretension is essential in assuring bolted joint integrity. Bolted joints are critical when ensuring safe operation of wind turbines or other similar bolted connections.

Bolt-Check is a bolt measurement system, which can maximise the reliability of the turbine, as well as reduce the need for maintenance and downtime.
Bolt-Check can be used when installing new bolts and when evaluating existing bolts as part of the determining the lifespan of wind turbines. The tool is suitable for most bolt types and requires no special pre-treatment of the bolts.

The advantages include:

  • A cost-effective solution
  • Reduce number of service inspections (no re-tightening)
  • Traceability (eliminate process risk)
  • Minimise the risk of failure
  • Improve utilisation of bolts
  • Maximise the operation time of the wind turbine
  • Possibible to track data and hosting of data which enables business intelligence
  • Bolt-Check products
