1. Environment friendly engine meeting Euro V emission standards isequipped with large displacement main pump, which has low energy consumptionand high efficiency.
2. Tailless design cooperates with boom swing function, which can adapt tothe narrow space operation flexibly.
3. The cab can be flipped up for easy maintenance.
4. Cab and base plate are integrated, which has strong noise isolation andhigh comfort.
5. The whole machine's weight is distributed reasonably improving theexcavator's digging stability.
6. The armrest can be flipped up for easy access to the cab.
