The Rotor Turning Gear is a multi-turbine tool which is installed inside the nacelle and can rotate the hub both with balanced and unbalanced rotor. The rotor turning gear comes with turbine specific interface kits to enable operations on different turbines. This tool can be used onshore and offshore (with specific modification required for offshore operations). The compatibility matrix includes currently developed interfaces, more interfaces can be developed by request.

The Rotor Turning Gear can be acquired together with:

• Upgrade kit for turbines which require supplementary motors in addition to the motor that is included in the base kit.
• Rotor Lock – mechanical locking system for high-speed shafts
