Both for pitch operation as well as for the different braking processes, a simple and directly effective system is a major advantage. The hydraulically-actuated HYDAC pitch systems provide further advantages and benefits in addition to fail-safe function:

• Quick and direct reaction by transferring the control signals on the actuators
• Simple and robust system
• More compact construction
• Quick operational readiness / restart after emergency stop due to short charging time on the hydraulic energy accumulator
• Low temperature influence up to −40°C
• Lubrication of gears or open toothing is not required.
• Long service intervals
• Reduced operating costs
