Wind Industry Profile of


ROEMHELD: “Rotorlock” locking system now rated for transverse forces of up to 7,500 kN and wind turbines up to 7 MW

Solid system for maintenance work on onshore and offshore stations

ROEMHELD has improved the performance of its modular locking systemRotorlock” for the inspection and maintenance of wind power stations. With a transverse force absorption of up to 7,500 kN, the systems reliably and safely lock rotors with a maximum capacity of 7 MW. Customer-specific variants with higher values are also possible. Due to their design and special coating, they are maintenance-free and corrosion-free through the entire service life of onshore and offshore stations.

The core of Rotorlock is a double-action, hydraulically or electromechanically driven pin that quickly and reliably locks the rotor disc. Non-contact position monitoring transmits the end positions “rotor disc locked” and “rotor released” to the system control and hence provides for extra safety for the operator.

At present, great interest for the locking system developed by ROEMHELD is shown by the offshore industry. Adverse weather conditions, temperatures between -30°C and +70°C and air with a high salt content are easily managed by Rotorlock. All components meet the corrosion protection requirements for offshore stations with a surface coating pursuant to DIN ISO 12944.

Special coating for long-term corrosion protection

A special coating provides long-term protection for the sleeve where the locking pin rests during wind power station operation. ROEMHELD warrants continuous corrosion protection for a period of 25 years and hence the typical service life of a wind power station. Regreasing as for other models is not necessary, either. The element is therefore practically maintenance-free and ready to use at any time.

Since only restricted space is available in most gondolas, the locking system has a specially compact design. As stated by ROEMHELD, the standard modular systems allows for offering special designs on the short term and at reasonable cost.
