1. Isuzu engine with strong power and high efficiency, saving energy and protecting environmental .
2. German Rexroth load-sensing system with low energy consumption and excellent operating performance, which can make it easy for the driver to complete complex moving so that the working strength will be reduced and the operating efficiency will be improved significantly.
3. Big excavation structure with side lift arm which will make the operating barycentre backward so that the complete machine stability will be enhanced during operation with greater digging force.
