Plant-specific brake control for wind turbines from the modular system

In the event of an emergency or planned maintenance/service, the turning of the fast shaft of the gearbox in a wind turbine must be braked safely or kept safe after stopping. For this purpose, a disc brake is positioned on the shaft in medium and large wind turbines. This can be reliably triggered and operated by a hydraulic power pack with attached manifold. Depending on the size of the brakes, HAWE Hydraulik quickly and easily designs the right compact hydraulic power pack from the modular system.

Directly flanged to the hydraulic power pack is the manifold, which is carried out in the HAWE Hydraulik solution with directional seated valves. You can choose between control blocks with screw-in valves or the service-friendly functional modular design. Due to their design, the directional seated valves integrated in both designs hold the brake in the tightened position for up to 8 days, even in the event of a failed electric power supply. In addition, a hand pump can be attached directly to the hydraulic power pack. With this, the brake can be activated manually in the event of maintenance.

With its compact power units, HAWE Hydraulik builds customer-specific solutions that can also be mounted directly on the rotor brake, thus avoiding unnecessary cable lengths. The power units can be arranged both horizontally and standing. As required in various countries of operation, they are suitable for "cold climate" and UL approved on request.
