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.
For small and medium-sized wind turbines, the blade tip brake used must be compact. This sits at the end of the rotor blades and leads to the aerodynamic deceleration of the rotor by adjusting the blade tip. This brake can be hydraulically driven.
Pitch controls and pitch drives are used to reliably adjust the blade angle to the wind in wind turbines. These are also a guarantee for the best possible energy yield from wind power and must work reliably over the entire service life of the plant. Current development trends show a continuous increase in pitch activity.
HAWE Hydraulik is merging its two existing production sites in China at a new, modern location in Wuxi. In the future, system solutions for key industries such as wind turbines, solar plants, machine tools and medical technology will be built here primarily for the local market.
