Wind Turbine Gearbox Workshop Services

Shortest turnarounds at industry leading quality standards.

Highest quality gearbox workshop services

Tailored solutions

Wind gearbox workshop services extend gearbox lifetime with innovative, proven and fit for purpose repairs. Alternatively, upgrade older gearbox configurations to correspond with the latest available technologies in the market. Moventas gearbox workshop service benefits from our experience in gearbox research and development, material selection and manufacturing processes. Our multi-brand workshop services can be tailored to fit your needs.

Testing capabilities

Our multimegawatt load testing capabilities across our global workshop network offers quality reassurance and physical validation, ensuring reliable gearbox operations in the turbine. This is a Moventas internal, and essential quality standard, not just a customer requirement. Running under controlled load conditions reduces surface roughness of the teeth as well as the risk of micropitting and scuffing.

Testing capabilities globally

All gear units serviced at Moventas Service Centers are test run prior to delivery to ensure reliable operations. For example, the UK’s only production test bench was introduced in 2016 by Moventas. Our test bench capabilities range from kW to MMW class, around the world.
