New Liebherr crawler promises higher productivity

LIEBHERR has started production on the new R 926 Compact crawler excavator, which features a Stage IV/Tier 4F emission-compliant engine and is described as offering higher levels of productivity and economy than its predecessor.

The new excavator joins the ranks of Liebherr’s Compact machines in the 15 to 35-tonne weight range, and offers enhanced Liebherr SCR technology, an improved tail swing and greater power, the manufacturer claims.

The machine offers an operating weight of between 25.4 tonnes and 29.5 tonnes, depending on the option selected. A tail swing of 1.7 metres and a front swing of 1.9 metres results in an overall swing radius of less than four metres, and is said to make the R 926 Compact “ideal” for applications in confined areas.

New hydraulic components offer increased productivity, with an 18% increase in swing torque of the upper carriage to 84 kNm, compared to the predecessor model. This improvement is particularly noticeable during loading processes and work on slopes, according to Liebherr.

The R926 Compact features a diesel engine, manufactured by Liebherr in Switzerland, which complies with Stage IV/Tier 4F emission standards. The engine can generate an engine power of 129 kW – an 8% increase compared with the Stage IIIB/Tier 4I predecessor model, Liebherr said.

The exhaust gas after-treatment also takes place without the need for a diesel particulate filter or an EGR drive.

The R 926 Compact excavator’s HD bucket volume can vary between 0.55 m3 and 1.5 m3, depending on the application, and the fully automatic centralised greasing system seeks to minimise excavator downtime.
