Roemheld has introduced new rotor locks for wind turbines. A special coating prevents the locking bolt from rusting when not in use for a long period and non-contact position monitoring avoids mechanical wear and extends the life of the component.
A permanently corrosion-free coating of the bushings prevents rusting between surface intervals and the need for regular greasing. The surface protection of all rotor lock components corresponds to DIN ISO 12944, C4, so that they can also be used in offshore operations. Non-contact position monitoring has also been introduced to offer longer life and high availability. A non-contact switch checks if the bolt is in stand-by position or if the rotor is locked. The rotor lock resists side loads up to a maximum of 7,000 kN and can be used to lock the rotors of onshore and offshore wind turbines up to 6.5MW.
