We make the generation of clean energy safe and efficient
mayr ® power transmission bundles its know-how and decades of experience in the offshore sector in safety brakes for pitch and azimuth drives. The safety brakes for wind power plants represent maximum fail-safe function, minimum downtimes and constructional design diversity, and reduce the operating costs. The company sets new standards with its Cold Climate Version, which is certified for applications to -40°C by Germanic Lloyd (GL).
And the portfolio is also wide for torque limiters. It extends from overload systems for wind turbine gearboxes via torque limiters for climbing aid drives in the tower and switchable clutches for the drives of maintenance and installation platforms, right up to high-performance large clutches for gearbox test stands.
