New rotor locks from Roemheld USA are designed to simplify maintenance for wind-power plants. The double-acting hydraulic cylinder locks the rotor blade up to 6.5 MW, from -30 degrees C to 70 degrees C.
The Roemheld USA rotor lock is available with hydraulic or electromechanical locking mechanisms and withstands side loads up to 5,500 kN. Other designs can be produced for special needs.
A new, long-lasting coating prevents rust in the locking bolt, and non-contact position monitoring avoids mechanical wear and extends component life. The surface protection of rotor lock components corresponds to DIN ISO 12944, C4, for use in offshore operations.
