Active Yaw wind Brakes
Yaw wind brakes are used for positioning and holding of pivot-mounted nacelles of wind turbines on the tower, where sensors permanently register possible deviations between actual wind direction and actual nacelle position.
Upon exceeding a permissible deviation, the yaw brakes are completely or partially disengaged in order to allow the re-adjustment of the nacelle by means of the yaw drives.
Subsequently, the clamping force of the typically active yaw brakes is generated again by applying the equivalent hydraulic pressure.

Active Rotor Brakes
Rotor brakes are an essential safety-feature of wind turbines. They are used for protection against overspeed as well as for stopping and holding the rotor, e.g. for maintenance purposes.
Depending on the drive concept, the brakes can be installed on the low speed rotor site, e.g. in gearless drives or on the high speed side at the gearbox output shaft.

Stopping and Holding Brake
Stopping and / or holding brake for wind power generators, blowers, turbines, coiler etc. The operating pressure is easily adapted to the operating conditions.
