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.
Case is increasing its presence in the earthmoving sector with the launch of a three-model range of upgraded M Series dozers, up from two models in the previous generation. The 1150M, 1650M and 2050M weigh in at 13-20tonnes and all feature Tier 4 Interim/Stage IIIB-compliant FPT diesel engines with selective catalytic reduction (SCR) technology. Case claims that the use of SCR results in lower fuel consumption, up to 10.5% less in the case of these dozers, while the 1150M and 2050M benefit from a 9% power i

A 6% increase in lift capacity, greater digging efficiency, reduced emissions and up to 5% lower fuel consumption are the benefits of Case’s new CX470C excavator. The 47 to 50tonne machine has a 9.8litre Stage IIIB engine delivering 270kW at 2,000rpm which contributes to a 5% increase in fuel efficiency and 5% faster cycle times. Some of the savings come from a Boom Economy Control, which automatically reduces engine revs and hydraulic power to the boom when speed and power are not a priority.
