We supply rotor locks for wind turbines applications.

Rotor Lock Systems

We supply various rotor locks for the use in wind turbines. The rotor lock is needed in order to stop the wind turbine for maintenance. The rotor lock that we supply has an electric indicator that gives a signal when the rotor lock is inactive so that the wind turbine can be in operation. When maintenance is needed the rotor brakes will stop the wind turbine from operating so that the rotor lock can be activated. The rotor lock is operated automatic or manually by using a hydraulic hand pump which we also supply.

The rotor lock is manufactured to specifically withstand the requirements of operating within harsh working conditions. The materials that are used are of high quality and the locking pin is hardened to withstand high radial forces. 

Advantages of our rotor locks:

  • Easy to operate 
  • High quality materials 
  • Electrical Positioning Signal, Locking pin in or out 
  • Operational in harsh working conditions, -40°C to 70°C 
  • Standard or offshore design
  • Position monitoring
  • Compact and maintenance-free design
  • Pilot operated non return valves
  • Additional mechanical block
  • Internal slide bearing
  • Easy apply of lock pin due to conical shaft-end
  • Offshore protection as per ENI 2944
