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.
CNH Construction marketing director Jean-Patrick Yekpe has highlighted the money-saving potential of Case Construction Equipment’s new midi-excavators, unveiled at bauma 2013. The Tier 4 Final requirements of the CX75C SR and CX80C have been met, says Yekpe, through the use of cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst system. “When the soot is coming out of the engine as smoke and touches the platinum inside the engine you get an oxidation, and as a consequence of thi
Tata Steel is aiming to double its worldwide steel sales by 2017 in the lifting and excavating sector from its current volume of 500,000tonnes. To achieve this target the company has recently invested €40million to improve its product portfolio, by developing its quenched and tempered, and advanced downstream processing facilities in the UK. Tata Steel said it delivers a wider range of differentiated steel products to the lifting and excavating industry than any other steel producer in the world, and provid

Komatsu has unveiled its 23,590kg operating weight WA470-7 wheel loader, which offers improved efficiency, lower fuel consumption, improved operator comfort and enhanced serviceability. It is powered by a 203kW Stage IIIB/ EPA Tier 4I Komatsu SAA6D125E-6 engine, which is said to lower fuel consumption by 10% to 15% compared with the WA470-6. The engine is fitted with EGR, a hydraulically-actuated variable geometry turbocharger, and an automatically regenerating DPF. As with all Komatsu Stage IIIB machines,
