Lower maintenance costs: Single-engine concept for large mobile cranes

Engine off.

Lifting capacity on.

We use an innovative drive concept for the crane superstructure on new models with five or more axles: The superstructure is powered by the engine in the undercarriage using a mechanical shaft. The power is transferred from the distributor gear in the undercarriage via two mitre gears through the centre of the slewing ring to the pump distributor gear in the superstructure.

• The undercarriage engine delivers enough power for crane operations at all times – even when running at low speed.
• The removal of the superstructure engine means increased economy and reduced maintenance work.
• The weight reduction due to the lack of superstructure engine is used to increase the crane’s lifting capacity.
