Products and Solutions Braking Systems It’s inspection time for a wind turbine. Before the engineers can access the nacelle the wind turbine must be stopped. In fact, exactly in a predetermined position. After all, the service staff must be able to gain access to the hub. This necessitates that the rotor is secured in a safe position. Compared to the past, this is easily accomplished today: the electro-hydraulic brake control stops the rotor exactly in the required position and automatically engages the rotor arresting system. So, this enables the Rexroth staff to do what is expected of them: Carry out the inspection. Technical features of the electrohydraulic brake control: Precise open-/closed loop control capability Very compact design Integrated safety functions Easy commissioning Highly environmentally compatible Designed for an operating time customary for this application Tailored solutions based on modular concepts Drive rating between 0.18 and 4.0 kW Volumetric flow rates from 1.2 to 14.8 l/min Tank capacity from 1 to 60 l Tank of steel, aluminum or plastic
