Wheeled excavators A 918 and A 918 Compact with redesigned cab
Liebherr is showcasing a total of four wheeled excavators at Bauma 2016. Some of the exhibits include the two models A 918 and A 918 Compact, which have already been retrofitted to comply with the new exhaust emissions standard IV. These machines have higher engine power with reduced fuel consumption and lower exhaust emissions.
Another highlight of the two machines is the revised cab for enhanced safety and comfort. A foldable armrest is included in the standard equipment which offers the machine operator enhanced safety when getting in and out of the excavator. The standard operation of the excavator support via the proportional control at the joystick levers offers greater comfort. When moving the machine the operator does not need to change his grip and can complete levelling works comfortably and precisely.
Both new Liebherr wheeled excavators are equipped as standard with the new automatic working brake. The service brake is opened automatically upon startup and closes again automatically when the machine is stationary. This ensures maximum safety and high productivity thanks to shorter response times.
R 936 crawler excavator
The R 936 crawler excavator presented at Bauma 2016 has been on the market since the beginning of 2016. It follows the first Stage IV / Tier 4f crawler excavator R 946, which Liebherr showcased at Intermat 2015 in Paris. Both crawler excavators incorporate the aforementioned new features of the hydraulic excavator range that comply with the exhaust emissions standard IV.
The operating weight of the R 936 is between 30 and 38 tonnes and the engine power is 170 kW / 231 HP. It is designed for earthmoving applications. With its new equipment it achieves maximum digging and breakout forces for a significant increase in productivity of up to 13% compared with the previous model. An optimised hydraulic system with dedicated swing circuit for increased productivity enables fuel savings of up to 7% with 10kW higher engine power in comparison to the previous generation.
