A Decisive Factor for the Purchase of a Liebherr Machine
The newest Liebherr drive and control systems offer several optional features that help to reduce fuel consumption and maximize the reliability and productivity of duty cycle crawler cranes as well as piling and drilling rigs.
Increased Power Through Engine Functions
Downsizing of the Engine
Thanks to the machine’s optimized hydraulic system the size of the primary source can be reduced without negative effects on the turnover. The efﬁciency is thus signiﬁcantly increased while the fuel consumption is decreased.
In the new duty cycle crawler crane HS 8130 HD, for instance, the engine power has been reduced to 505 kW compared to 670 kW in the preceding model.
Engines of the Latest Generation
Deep foundation machines are ﬁtted with Liebherr’s own diesel engines. All diesel engines complying with Stage IV/TIER 4f have a limited maximum speed of only 1,700 rpm. This contributes to fuel savings of approximately 5% compared to previous engines.
