Advantages and highlights:

* More energy-conservation and environmental protection By adopting Yanmar enginemeeting national stage III emission standard,mechanical fuel injection pump has reliable performance. With compact size, the maintenance is convenient. Enough low torque reserve can ensure strong power. High reliability can reduce the maintenance cost.

*  More efficient return Rear-end swing radius adopts tailless design, which can ensure that the tail part will not collide with obstacles under narrow working conditions.Deflectable working device can deflect to left and right at 75° and 50° separately, which can achieve compound action with superstructure. Through swing cooperation with superstructure, digging operation parallel to the wall surface will be achieved and various kinds of working conditions can be coped with easily.
