Liebherr launching a revised R922 crawler excavator
718 Liebherr is launching a revised R922 crawler excavator, replacing the previous R906 and joining the R918 and R926 in the company’s medium weight line-up. Powered by a Stage IIIB Liebherr diesel engine, developing 105kW (143hp), the R922 weighs in at 22 tonnes and designed as a general purpose civils machine. Using a Dual Circuit Positive Control hydraulic system, the excavator is said to consume less energy than previous models, resulting in fuel savings for the customer. The machine on show will be exhibited with a 2.7m dipper arm and LC undercarriage. However even with 600mm track pads the R922 does not exceed the 3.0m overall width for road transport in Europe.

Like its fellow new 9A series hydraulic excavators with engines above 130kW, the engine on the Robex R380NLC-9A hydraulic crawler excavator from Hyundai Heavy Industries (HI) comes with an EGR and diesel particulate filter (DPF). The DPF is said to be automatically or manually regenerated, ensuring compliance with all NOx and PM values. According to Hyundai HI, DPF filters only need to be cleaned after 5,000 to 6,000 hours in operation.
