摘　　要：针对DCY-4铲运机铲取无力的现象,通过对原设计中功率和扭矩消耗的分析,得出铲取无力的主要原因是铲取工况下液压系统功率和扭矩分流过大导致牵引力降低。提出的改进方案在不需要增加泵、阀等大的投资情况下,既能提高铲取力。Aiming at asthenic scraping of DCY-4 excavator, by analysis to consumption of power and torque in original design, the paper concludes that asthenic scraping is due to excessive distribution from torque and power of hydraulic system in scraping circumstance, which lead to debase drawing force. Scraping force not only could be enhanced but requirement of bucket retracting time be met by improvement without adding pump and valve etc
