摘　　要：对一种采用比例减压阀和比例溢流阀控制液压马达恒定扭矩的绞车原理进行详细分析。这种方式适用于小功率的绞车,且系统简单、控制容易,可以和其他液压设备共用液压源,减少系统投资。The principle of the hydraulic winch controlled by hydraulic motor constant torque using proportional pressure reduc- ing valve and the proportional relief valve was analyzed in detail. This approach is suitably applied to small power winch, and the sys- tem is simple, which is easily controlled. The hydraulic source can be shared with other hydraulic equipment, and the system invest- ment is reduced.

关 键 词：液压绞车 张力控制
