lightweight & noise-free systems for wind turbine braking and gliding

DELLNER BUBENZER offers lightweight, noise-free systems for braking and gliding processes in wind turbines. Noise reduction has been the core focus in the development of this comprehensive range of brakes and sliding bearings, recognizing that noise prevention plays a substantial role in the overall acceptance of wind energy.

A hydraulic rotor lock offering up to 210 bar pressure with an activation time of 60 seconds.

We offer three models of the JHS-R240 hydraulic rotor lock – the GL Type Certified JHS-R240, the JHS-R240-M and the JHS-R240-154. All these locks deliver up to 250 bar pressure with an activation time of just 35 seconds.

Due to its high capacity, our SFRA brake is mainly used as a rotor brake in wind turbines. It is particularly suitable for applications with a high duty cycle.
