Wheeled excavator currently in China is mainly used in the municipal drainage pipeline laying,maintenanceengineering,, traffic construction and rapid repair, mining,transport and materialremoval, greening.
Di Pengyuan thinks, wheeled excavator as supplementary crawler excavator, itself is the auxiliary equipment,notdominant. But with the progress of urbanization construction, wheeled excavator will play an even greater advantage.Because of low efficiency, poor stability, it is not applicable to earthwork construction large, suit to do maintenance work, similar to the "two busy" role. But the lifting function is "two busy" can not be replaced.In addition, the diversification of working device will also provide good support for wheeled excavatormaintenance work. He thinks,wheeled excavator belongs to a niche product, only to improve the stability,efficiency and safety performance,strengthen the configuration difference of working device, can expand the operating range, and increase market share.
