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. At the same time, the functionality of the drives has a considerable influence on the service life of other components such as the tower and foundation.

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.

在遇到紧急情况或计划维护或售后服务这些情况下，齿轮箱中极速转动轴必须安全制动或停止后保持安全。为了达到这个目的，在中型或大型的风机的轴上，都装有碟刹。这样就可以通过带阀组的液压泵站启动和运行了。根据碟刹的规格不同，哈威液压可以用其模块化系统来简便快捷地设计最合适的紧凑液压泵站。   

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. With its specially tailored mini hydraulic unit, HAWE Hydraulik offers not only a very compact, but also a very robust solution. This reduces the maintenance effort and increases the reliability of the complete system.

在小型和中型风机中，使用的叶尖制动必须紧凑。它位于风轮叶片的底端，通过调节叶尖来引致风轮的气动减速，制动是由液压驱动的。哈威液压提供的这款特别定制的迷你液压单元，不但极其紧凑，而且非常强劲。它减少了维护方面的工作且增强了整个系统的可靠性。   

HAWE Hydraulik has developed an integrated hydraulic solution for mobile machines in order to transfer the advantages of the CAN bus in the control of main functions to secondary functions. As a result, the machine manufacturer not only saves time during assembly, but also weight and installation space in the vehicle. This new manifold MICK is designed for use in the concrete pump. Particularly advantageous is its use in mobile machines with several consumer groups, which work sequentially and are operated separately from each other.
