R956 Liebherr Crawler Excavators 

Liebherr Crawler Excavators

Equipped with a stage IV liebherr engine with gas after treatment system, the R 956 has also a proven hydraulic system with separated swing circuit to increase productivity. New confort and safety options have also been adopted.The combination of the new Liebherr engine and SCR system offers a highly efficient and simple solution. Reducing the after treatment system complexity, while also achieving improved combustion, increases the serviceability and reduces the overall consumption of DEF and Diesel. Productivity and profitability are increased thanks to increased fuel efficiency and optimized hydraulics.

  • The Regeneration Plus function allows for the accelerated lowering of the boom, reduced losses of pressure and an improved work cycle.
  • The new Liebherr engine, pursuant to the Stage Tier 4 emission standards, comprises a diesel exhaust fluid injection device (SCR) for the after-treatment of exhaust gases, with no need for a particle filter, diesel oxidation catalyst or EGR.
  • With an X-shaped design and an increased slewing ring diameter, this new undercarriage is characterized by an even distribution of stresses over the whole structure. This results in increased performance, greater load properties and an increased service life.
