The mainframe is the central component of the generator nacelle on a wind turbine. The gearbox, the rotor bearing and the bearing for the connection to the tower are flange-mounted on the mainframe. The generator frame holds the electricity generator.
Mainframes weigh up to 70 tonnes and are exposed to permanent and high dynamic loads. Their manufacture must meet the most rigorous quality and safety requirements. Our highly precise tools for drilling and milling meet these high requirements
