Rotor turning gear

Our rotor turning gear cools the hot rotor of a steam or gas turbine by turning slowly, thus maintaining dimensional stability.  Rotary units ensure breakaway, starting and positioning of the shaft trains.

The use of a swiveling pinion offers a high degree of flexibility as there is no need for any shaft end.

In close cooperation with our customers, we have developed rotary devices for turbines in power plants of various power classes corresponding to specific requirements.
