Put to work in April 2017 the Liebherr R 956 has been deployed four days a week with an average daily output of 2000 m3. The excavator is equipped with a 6.70 m boom and a 2.90 m dipper stick with additional cylinder covers for loading a HD bucket with capacity of 2.7 m3.
With a HD undercarriage, 2900 mm track gauge and 600 mm track pads, the R 956 continuously loads three articulated dump trucks, thus ensuring the transport of the quarried materials. These dump trucks have a struck capacity of 16.9 m3 and a refill capacity of 22.5 m3, SAE 2:1.
Fast, versatile and comfortable
A new diesel engine with a power output of 240 kW / 326 hp and the SCR system for the aftertreatment of exhaust gas (without particulate filter) make the R 956 compliant with the emissions standards of Stage IV / Tier 4f.
Fast and versatile, the R 956 crawler excavator allows precise and careful work. Thanks to their kinematics and hydraulic power they are capable of higher breakout and digging forces even in extreme applications
The operator cab provides a comfortable, spacious and ergonomic work space to allow for maximum productivity. Mounted on visco-elastic elements, the cab is not subject to vibrations. Fully automatic air-conditioning and a high-resolution touch screen also enhance the operator's comfort.
The operator has excellent visibility of the surrounding area thanks to a standard rear-view camera and a lateral camera as well as an optimised uppercarriage design. For enhanced safety the R 956 also has a fully removable laminated windshield under the roof and a secure emergency exit at the rear of the cab.
