Rotor locks are used in the wind turbine industry and are typically mounted to the turbine´s main rotor shaft, between gearbox and generator. A rotor brake is primarily intended for use as safety brake during emergency stops under high wind conditions. Svendborg Brakes rotor lock units hold a global market leading position. The rotor lock is activated by running the lock bolt into the lock disc using hydraulic power; a "locked" signal is then transmitted to the control system. The units are engineered to handle the large output torque generated by the high ratios found in wind turbine gearboxes.
