Liebherr has announced it has started production of the newest version of its compact crawler excavator. The first of the latest version of the R 926 model to come off the production line occurred at the company’s factory in Colmar, France.
Whereas older versions of the vehicle include a Stage IIIB engine, this machine is equipped with a new Stage IV/ Tier 4f emission-standards compliant engine, generating power of 129kW, which is an 8% increase on the older engine.
The exhaust gas aftertreatment is carried out without the need for a diesel particulate filter or an exhaust gas recirculation valve, ensuring maximum machine reliability.
Available in two differing weight options, 25.4 metric tons or 29.5 metric tons, the vehicle’s dimensions have been reduced with a tail swing of 1.7m and a front swing of 1.9m giving it a swing radius of less than 4m.
Improved swing torque
An improvement in swing torque of the upper carriage of 18% compared with the predecessor means the vehicle offers 84kNm, which is particularly noticeable in loading processes and when working on slopes.
The standard fully automatic centralized greasing system guarantees regular lubrication, thereby minimizing the compact excavator’s downtime. As the maintenance is easier and faster to perform, the operator enjoys greater flexibility and a high degree of machine availability.
A Liebherr spokesperson said, “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.”
