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.
Hidromek has added long-reach options for three of its excavators – the HMK220LC, HMK300LC and the HMK370LC. Aimed at special earthmoving and drainage applications, the excavators carry LR branding and have ground level reach of 15.06, 18.19 and 16.6m respectively. Load over heights range from 10.85m with the HMK220LC LR to 12.59 with the HMK300LC LR. The long-reach HMK220LC delivers 7,300kgf of bucket digging force with a 0.45m3 bucket, with the figures rising to 1m3 and 11,400kgf with the HMK370LC LR.
