Tailored solutions
thanks to perfectly compatible and proven components for the industrial gear unit combination to meet your needs.
High operating reliability
thanks to our efficient cooling concept that ensures the reliability of your system.
High power transmission
thanks to the high torque in a compact housing with robust technology.
The cutting ring or drill head on the tunneling machine generally has a circular drive: several pinions are installed on the circumference of the circular main bearing with internal gearing, which are hydraulically or electrically driven by planetary and bevel-helical gear units. Slip clutches with a slip monitoring system are also located between the motors and the gear units. This prevents the entire drive system from overloading if the cutting head becomes blocked.
This solid mechanical engineering technology requires industrial gear unit solutions that are just as solid and reliable. All of the components in our drive system have been built to withstand the challenging operating conditions. Our efficient cooling concept for tunnel boring machines ensures a high level of reliability and the long service life of your system - and you also save on the need for external cooling units and a larger gear unit.
