Liebherr’s new 50-tonne class R 956 crawler excavator at Conexpo 2014
Liebherr's new R 956 crawler excavator
Liebherr’s new 55.4tonne R 956 crawler excavator fitted with the firm’s own six-cylinder diesel engine with common rail fuel injection replaces the previous R 954 model.
Among the features enabling the R 956’s Liebherr engine to comply with Tier 4i / stage IIIB exhaust emission standards are an external exhaust gas recirculation system and a diesel particulate filter with active regeneration.
The steelwork for the new crawler excavator model’s upper carriage is said by Liebherr to be optimised for extended service life. A wide variety of undercarriages are available to suit any application. The LC is the typical under-carriage for earthmoving applications, with two ‘heavy-duty’-undercarriages HD and S-HD also available for quarry applications.
