Wind gearboxes

Eickhoff’s technical expertise and experience in the wind turbine gearbox sector has been playing a part in the development of innovative and efficient wind power concepts for our customers throughout the last 20 years. As a key element in the drive train, our high-performance, high-quality gearboxes, optimised for production and cost-savings, are impressive due to their maximum robustness, maximum reliability, long service life and extremely compact design. They are designed to suit the customer’s specification and the respective requirements exactly with a high power density. Our 5 MW test bench and environmental test chamber help us to verify compliance with the quality demands of our customers. All tests are logged precisely. For example, we test all prototype gearboxes under representative loading conditions and, if required, also subject them to a temperature of –40 °C (–40 °F) to check their low-temperature suitability. In addition, we offer our customers bespoke service and maintenance concepts, which enable them to reduce their operating costs and at the same time optimise their plant availability by way of faster reaction times.
