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.
The new 700CT Series integrated hydraulic motor drive from Bonfiglioli is designed for use in compact track loader. Said to suit closed circuit applications, this drive range offers compatibility with the previous 700CK Series in closed circuit applications. The new product features the same chassis side and sprocket side dimensions and does not require machine manufacturers to change the design of their present gear motor drive train interface. Compared to conventional drives, however, the new hydraulic mo

Due to an innovative and strong frame design and the use of premium raw materials and components, Getech/Gennaretti centrifuges can be employed across mining, tunnelling, petroleum and chemical industry-based sludge treatment processes. They can also be built in mobile plants on containers, easy to transport to remote areas and quick to install, able to manage sludge volumes going from 5 to 150m³ per hour.
Having a long tradition of CG rollers, without central articulation, but with steering on drums, Atlas Copco’s Road Construction Equipment division now launches the Dynapac CG2300 asphalt roller. The roller is 3.95m long and 3m high with an inner turning radius of 3.1m. This means transportation advantages as well as ease of working in restricted areas.
