A mechanical shaft ensures particularly high efficiency and thus guarantees the economy of the new concept in terms of fuel consumption.

Components

At Bauma China 2018, Liebherr presents itself as a components manufacturer for the tunnel construction segment. The focus thereby lies mainly on the new gearbox series and electric motors, which are presented to the trade public for the first time in Shanghai (China).

Components by Liebherr have been proven themselves in tunnelling projects around the world for several years now. For example, slewing bearings with a diameter of up to 9,000 mm, which keep turning cutterheads in India, Africa, the UK and China. Also axial piston units have shown their value in tunnelling applications. Liebherr hydraulic pumps are used, for example, in medium-sized tunnel boring machines for hard and soft rock with a diameter of up to six meters.

All individual Liebherr components are characterised by their particular robustness, reliability, availability and long life expectancy. They are perfectly matched to each other according to customer requirements and can therefore be used as an integrated drive system, for example for the cutter head in tunnel boring machines. With the exhibited system, Liebherr also demonstrates the possibilities for system solutions in this area.
