In this year (2022) The BMW Show in Munich, Germany (Bauma) Go，For the first time, Liebherr has launched its first machine from Colmar, France.Liebherr-France SASHydrogen-engine-driven crawler hydraulic excavator developed and manufactured by the companyR 9XX H2。

In terms of dynamic performance and responsiveness, everyone is most concerned about.，Hydrogen excavators compare favorably with any conventional powered excavator，Can achieve the same overall performance as a diesel-powered excavator，Nor does it depend on a continuous supply of energy.。When used on a construction site，Hydrogen excavators emit almost no carbon dioxide.。The machine is in its full life cycle.，Carbon dioxide emissions will be 70% lower than the same level of traditional internal combustion engine powered excavators%。

  

For application conditions，Even at extreme temperatures、Under the working conditions of large impact and high dust，The hydrogen excavator is still powerful and does not drop the chain.，Strong and stable productivity for applications such as earthworks and quarrying。

  

It is worth mentioning that，Hydrogen excavator“Heart”——HThe 966 hydrogen engine is elaborately developed by Liebherr Parts Division.。The six-cylinder engine is based on hydrogen multi-port port injection (PFI) Develop the technical scheme，An extremely lowNOxAndCO2 Discharge。

  

HThe prototype of the 966 six-cylinder hydrogen engine was Liebherr.

Core of the first hydrogen crawler hydraulic excavator。

Liebherr is committed to the development of alternative energy drive solutions.，The hydrogen internal combustion engine is one of the technical solutions developed by Liebherr.。The Liebherr Components Division is also committed to the further development of power technology solutions based on hydrogen energy，Include“Hydrogen in-cylinder direct injection (DI)”Technical proposal。Hydrogen engine equipped with the latter technical scheme，Compared to the use of the developed“Hydrogen multi-point air passage injection (PFI)”The engine of the technical scheme has higher power density.，It will make it a more ideal choice for heavy duty applications in harsh working environments such as construction and mining.。

  

In this year (2022) The BMW Show in Munich, Germany (Bauma) Go，Via Messe Munich and the Association of the German Mechanical Engineering Industry (VDMA) And from the German Construction Industry Federation (HDB)、Federation of the German Construction Industry (ZDB) German Federation of Building Materials (BBS) Many experts from other institutions evaluate it.，Liebherr Hydrogen Crawler Hydraulic Excavator Relies on Practical Orientation、Economic potential、Environmental protection、Resource conservation、Numerous advantages such as efficiency and workplace humanization were awardedBaumaInnovation Award。
