Wind turbine gear manufacturer Moventas says it is expanding its up-tower service. The company says it can perform on-site inspections and repairs of high-speed, low-speed and intermediate assemblies for both its own gearboxes and competitor models.
By utilizing a mobile service unit and a small hydraulic crane, the Moventas up-tower repair eliminates the costs associated with mobilizing large boom and secondary cranes that are usually required to bring the complete gearbox down from the nacelle, the company explains.
This method also reduces costs related to shipping and wind turbine downtime, according to Moventas.
The company says it is currently building multiple self-contained mobile workshops specifically designed to perform this service at the wind site. Five mobile workshops will be located in North America, and two will be located in Germany and Spain before the end of the year.
