Reliability in tunnel construction - thanks to powerful industrial gearbox solutions

Modern tunnel boring machines consist of a rotating boring head, followed by a main bearing and a thrust system with downstream safety systems. The choice and type of tunnel boring machine depends, among other things, on the geological conditions and the amount of groundwater available. For every type of tunnel boring machine - and for every environment, no matter how harsh - we offer you a combination of the robust helical bevel gearboxes from the industrial gearbox series X and the planetary gearboxes of the P series the perfect drive solution. In combination with a wide range of available accessories and options, you can reliably cover all drive requirements for your tunnel boring machine.

Solid, powerful, durable: our drive system for cutting wheel and cutterhead

The cutting wheel or cutterhead of the tunnelling machine usually has a ring-shaped drive: a ring-shaped large bearing with internal gearing is fitted with several pinions on the circumference, which are driven hydraulically or electrically via planetary gears and bevel helical gears. Additional slip clutches with a slip monitoring system are located between the motors and the gearboxes. This prevents overloading of the entire drive system in the event of a blockage of the cutting head.

This solid mechanical engineering technology requires both solid and powerful industrial gearbox solutions. All components of our drive system are up to the required operating conditions. Our efficient cooling concept for tunnel boring machines ensures high reliability and a long service life for your system - and saves on external cooling units and a larger gearbox.
