Liebherr has introduced new Compact wheeled excavators which comply with Stage V exhaust emissions standard. The A 910 Compact Litronic and A 912 Compact Litronic wheeled excavators are the two smallest models in the Liebherr Compact range. The A 910 Compact has an operating weight from 12,100 to 13,100 kg and an engine power of 85 kW / 116 hp. The A 912 Compact is the next biggest machine with an operating weight from 13,000 to 14,200 kg and an engine power of 90 kW / 122 hp.
“In order to observe the strict statutory emissions standards of Stage V, at Liebherr the latest engine technology is used: the innovative exhaust emission control system combines a diesel oxidation catalyst and a diesel particulate filter with a SCR catalytic converter for the reduction of particles and nitrogen oxide for optimal protection of people and the environment against exhaust gas pollutants,” explained the manufacturer.
In the course of the changeover to the new Stage V exhaust emissions standard, the counterweight for the A 910 Compact and A 912 Compact was increased. With the heavier counterweight, the two Compact wheeled excavators have higher lift capacities of around 100 kg with maximum jib length. At the same time, the heavier counterweight ensures enhanced stability of the Compact wheeled excavators, which also results in better stability during dynamic movements.
The two Compact wheeled excavators are available with different supports. Different combinations for the stabiliser blade, outriggers and split blade are also possible. The Liebherr Compact wheeled excavators are designed with reduced tail swing for applications in confined spatial conditions on construction sites. The tail swing for the two Compact wheeled excavators is 1,675 mm. In addition, the front swing radius was reduced by another 70 mm so that the entire envelope circle is under 5,000 mm for both machines.
“Despite the compact machine dimensions, the A 910 / A 912 Compact machines have high digging forces, also in hard ground. Liebherr Compact wheeled excavators can therefore be used universally on every construction site,” added Liebherr.
