Liebherr updates its R922 crawler excavator with more power
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.

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.
Sennebogen has plugged the gap in its telescopic crawler crane range with the introduction of the 673R-HD. The 70tonne capacity machine sits between the firm’s 40 and 80tonne models, offering a 36m four-stage main boom with two fly booms of 8m and 15m. This gives a maximum reach of 51m. The 673R-HD is powered by a Stage IIIB/Tier 4 Interim standard Deutz engine delivering 160kW. Telescopic track frames allow for a maximum transport width of just 3m, with fast set-up on site as they extend out to provide sta
Hitachi Construction Machinery is showing four models from its Zaxis 5 range of wheeled excavators. The ZX140W-5, ZX170W-5, ZX190W-5 and ZX220W-5 all feature Isuzu Stage IIIB emissions-compliant engines powering the HIOS III hydraulic system. They benefit from increased lifting capacities, as the power boost function has been increased by 11%. The machines have a revised ROPS cab that has been redesigned to improve visibility.

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 –
