Quarry specification excavators
The R 950 SME and R 970 SME will be on display alongside a number of other fuel-efficient hydraulic excavators including an R 956 from Liebherr Rental that will be in action on the quarry face. All three machines are powered by a Stage IV/Tier 4 final Liebherr diesel engine and use SCR technology, removing the need for a DPF or regeneration.
The R 950 SME is fitted with undercarriage components from the 60 tonne model and the increased diameters of stick and bucket cylinders, along with the special heavy-duty boom and stick, deliver higher breakout and exceptional digging force. Other features include a 7” high-resolution colour touchscreen in the cab and rear space and side monitoring cameras to provide all-round visibility.
The stability of the R 970 SME is maximised with an undercarriage from the 90 tonne model and powerful digging force is provided by the reinforced heavy-duty boom and stick, which have steel protection plates welded on, and the substantial hydraulic cylinders. The available purpose-built heavy-duty rock bucket and ripper tooth increase digging and breakout forces to over 15 per cent.
The R 956 crawler excavator is a high-performance machine for mass excavation work or for digging in quarries. Its state-of-the-art hydraulics system provides maximum efficiency, responsive smooth operation and rapid work cycles. All major components are in-house designed and engineered to assure consistently high quality thereby minimises cost and downtime.
Highlighting the work undertaken by Liebherr’s workshop team at its state-of-the-art facilities in Biggleswade, a refurbished R 924 HDSL material handler will be on the Liebherr stand. Anyone who has seen this machine can’t believe it’s not brand new and we will be offering visitors to the Liebherr stand the opportunity to guess the hours on the clock for a chance to win a scale model of the L 566 XPower®.
