Recently, XCMG’s first XE210WLL extension armed wheel type hydraulic excavator successfully rolled off the production line. It is developed and produced based on 21t wheeled excavator. The movable arm is 7.15m long, the bucket rod is 4.5m long, and the maximum excavation radius is 12.6m, which enables the machine to work in a large range. In the meantime, the rotatory support with larger diameter is used and the landing leg is welded on the lower frame, which brings better stability performance. This type of excavator has excellent maneuverability and controllability and is mainly used in the earthwork excavation such as building transfer, expressway slope paving, river channel dredging and deep trench dredging. Under current gloomy market situation, XCMG has taken the initiative to make changes, focus on technical upgrading and promote product spectrum improvement, so as to satisfy the diverse needs of markets and customers.
