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.
Michelin’s X-Crane tyre for mobile cranes has evolved into the X-Crane+, offering lower rolling resistance, improved tyre life of up to 15% and greater durability before irregular wear characteristics can be detected, it is claimed. Available in the most popular 445/95 R25 size, the X-Crane+ offers an F speed rating and a 6,700 kg payload, and has been engineered to be easier to mount and dismount from its wheel rim.
Deutz used bauma to show two hybrid projects it is currently working on, including a hybrid drive for excavators and an innovative start/stop system for compact wheeled loaders. The hybrid drive is based on using a 160kW Deutz TCD 6.1 L6 engine with an integrated motor-generator. The engine is linked to an on-board electrical power network that uses super capacitors, a power inverter and an electric slew motor, allowing components to harvest, store and use electrical energy, specifically for slewing functio
