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’s new 655 HD heavy-duty cycle crawler crane is one of several innovations on the company’s stand at Bauma. Designed for heavy-duty tasks on construction sites and in the extractive industry, the 655 D can be used with a dragline bucket or in foundation construction. The 55tonne capacity machine can be used with a 3.5m3 Hendrix dragline bucket, for instance, and it uses two 16tonne winches driven by high-pressure regulated variable displacement hydraulic motors. There is a continuously-variable fr
Hamm continues to develop its sophisticated soil compactor range with the addition of models aimed at the 11-16tonne weight classes. These are powered by Tier 4 Interim/Stage IIIB compliant diesels and share the same design concept as well as features and many components with the existing 18-15tonne rollers. The high compaction performance and unobstructed sight lines from the cab of the larger machines have also been carried over into the smaller units. The H11i, H13i and H16i compactors have 2.14m wide d

Innovative simulation technology is now available from German specialist, CONWORLD. The company claims its technology can be used for operator training, with simpler systems also available for gaming. The company says that its simulator systems can be used to educate construction machine drivers at the beginner level and save on diesel fuel, as well as reducing the risk of damage to costly machines and potential accidents.
