【Abstract】 The electronically-controlled energy-saving technologies secure a crucial position in power matching for excavator electrically-controlled systems.Based on a review on characteristics of electronically-controlled systems in foreign excavators,the advances of domestic excavators and gaps between them are analyzed.It is implied that several new technologies,which focus on intelligent electro-hydraulic yet energy-saving control,will be integrated and investigated into the excavator electrically-controlled systems.更多还原
