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.
While lift heights remain unchanged from 10-13m, increased lift capacities can now be found across Liebherr’s four-model telehandler range, which now offers 4.1 and 5 tonne lift capabilities. And the range has been rebadged to reflect the new muscle now available. It means models numbers become TL 441-10, TL 441-13, TL 451-10 and TL 451-13. All models use a four-cylinder turbocharged engine rated at 74kW, with a hydrostatic transmission taking care of drive to all four wheels. Three steering modes remain –
Doosan says its two new large Stage IIIB compliant crawler excavators in the 50tonne class offer the strength and productivity needed for heavy duty work such as large-scale earthmoving, moving rock, and secondary breaking projects found on quarrying and mining, highway, aggregate, demolition, and other construction projects. The 49 tonne DX490LC-3 and 52 tonne DX530LC-3 are said to have excellent fuel efficiency, while representing an excellent return on investment for civil engineering companies, major co
Weighing in at 42-43.3tonnes depending on specification, the new Doosan DX420LC-3 excavator is Stage IIIB/Tier 4 Interim compliant and offers significant benefits over the model it replaces. Improvements include an increase in power, boosting overall productivity and the machine can be used in heavy-duty applications such as earthmoving, demolition and quarrying.
Superior Industries, which claims to be North America’s only combination manufacturer of conveyor systems and their related accessories, has said it plans to pursue new international dealer candidates at bauma 2013. It is asking dealers interested in distributing its brand of conveying equipment and/or conveyor components to complete a pre-show questionnaire at superior-ind.com/bauma.
