Production is now underway on Liebherr’s new R 926 compact excavator.
The new model continues Liebherr’s compact excavator product line, but with a Tier 4 Final engine and other developments compared to its Stage 3B model. The new R 926 Compact joins the ranks of Liebherr’s compact machines in the 15 to 35 tonne weight range.
Enhancements include Liebherr SCR technology, improved swing torque and greater engine power. The improved innovative maintenance concept enables simplified, safe and fast maintenance and repair of the machine. Overall, the new compact excavator achieves higher levels of productivity and economy compared to the previous generations.
Depending on the options selected, the new Liebherr R 926 Compact offers an operating weight of between 25.4 tonnes and 29.5 tonnes. With a tail swing of 1.7 metres and a front swing of 1.9 metres, its dimensions have been further reduced. Altogether, this results in a swing radius of less than 4 metres, making the new compact excavator ideal for applications in confined areas, according to Liebherr.
The new R 926 Compact’s diesel engine is manufactured by Liebherr in Bulle, Switzerland and complies with Tier 4 Final emission standards.
It generates a higher engine power of 129 kW, which is an increase of 8 per cent compared to the previous model.
The exhaust gas after-treatment takes place without the need for a diesel particulate filter (DPF) or an EGR valve. A renewal of the filter regeneration is not required. Maintenance times are also eliminated and there are no associated spare part costs with the exhaust gas after-treatment.
Higher swing torque
New hydraulic components in the new R 926 Compact guarantee an increase in productivity compared to the earlier model, according to Liebherr. The improved swing torque of the uppercarriage is 84 kNm, an increase of 18 per cent compared to the previous machine. The improvement is noticeable in loading processes and work on slopes.
Liebherr offers a wide variety of equipment variants so that each crawler excavator can be tailored to specific customer requirements. Depending on the application, the customer can choose from a broad range of HD buckets and special tools, produced in-house by Liebherr. As a result, the R 926 Compact excavator’s HD bucket volume can vary between 0.55 cubic metres and 1.5 cubic metres.
As well, the standard fully-automatic centralized greasing system guarantees regular lubrication, thereby minimizing the compact excavator’s downtime.
