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.
Scania will be showing both Euro 6 engines for its on-highway truck range and Stage IIB/Tier 4 Final powerplants for off-highway use. The company will use both exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) to meet the coming regulations, as with its current Stage IIIB solution. This means the fitting of a diesel oxidation catalyst (DOC) but no requirement for a DPF. Scania engines are currently in use in Terex and Doosan articulated haulers, along with a number of Terex crushing ma
