The each optional check valves and mechanical latches serve as a second backup of the system. Optima workholding offers the HRV rotor locks with pin diameters from 120 mm (120-50 HRV) 240 mm (HRV 240-80). Depending on the model the components for shear forces are up to 4,000 KN. The end positions of the locking element displayed by two mechanical limit switches and can be visualized using the machine control system. So, the operator immediately detects the condition of the plant. The components of HRV are corrosion resistant and suitable for the standard for use at temperatures between – 30 C and + 60 C. The electro-mechanical rotor locks of the series ‘ERV’ are, however, brought by an Electromotor in position.

The advantage of this system is that you do without oil transfer hoses. The component also has a mechanical self-locking design. All functions can be easily monitored. The standard version is the electromechanical rotor locking (ERV 240-80) with a Bolt diameter of 240 mm and lateral forces designed up to 4,000 KN. As for the hydraulic system is controlled through two mechanical limit switches. One inductive proximity switch is indicative of a previously defined force which pushes the bolt against the rotor disc.

Thus not enough: For customers who place special demands on the rotor locks for their wind turbines, the team by Optima workholding develops tailor made solutions on the basis of the two systems. This one covers the complete services of project management – from intensive consultation to rebuilding and retrofitting existing plants. Even costly special constructions without long lead times are available through a dense network of distributors all over the world.
