Here is a brief overview of selected HAWE products at WindEnergy 2024:

Hydraulic pitch module

With a hydraulic pitch drive, the angles of the rotor blades are adjusted using hydraulic cylinders. This optimizes the energy yield and at the same time reduces the mechanical load on the wind turbine, which extends its service life.

The HAWE pitch module consists of the cylinders, hydraulic accumulators, control blocks with a highly dynamic and precise proportional valve, directional and pressure valves. If required, it is supplemented by the necessary piping, hoses and fittings as plug&play solution.

Visualization of brake pressure characteristics

Our new measurement model is used to visualize pressure rise and pressure drop characteristics on yaw brakes by changing the parameters of the installed hydraulic components. The requirements of wind turbine manufacturers are becoming increasingly demanding and even a proportional control system is already at the experimental stage. In this way, much more expensive wind turbine components can be protected and their service life extended.

Decentralized control unit for rotor brake and rotor lock

Due to their small dimensions, the compact power packs type KA and CPU are ideally suited for a decentralized arrangement directly at the rotor brake or the rotor lock of the wind turbine. Long tubing connections with correspondingly high costs and installation efforts can thus be avoided.

This is particularly important as the distances between the hydraulic consumers also increase with increasing plant size. The power units can be equipped with all function modules and are thus a very flexible solution.

Tool-operated pump for rotor brake

A rotor brake is currently operated with a hand pump in the event of a loss of voltage or maintenance. The low delivery volume of this requires a high number of pump strokes. This is often physically strenuous. To avoid this, HAWE Hydraulik has developed a tool-operated hand pump with which the necessary brake pressure can be built up without great effort using a ratchet or even a cordless screwdriver.

Sys_Spare_parts_for_Wind_turbines.rgb.100x100

Aftermarket solutions for wind turbines

In addition to our hydraulic system solutions for wind turbine OEMs we offer engineering services, spare parts and retrofit solutions, tailored to your wind turbine type and geographical location. With more than 30 years of experience, we have faced almost every challenge in the wind energy sector.
