单斗挖掘机工作时,要求其传动系统具有所谓“挖掘机特性”,即当工作装置遇到重负荷时,传动速度能自动地显著下降,使司机能够察觉,从而操纵挖掘机来减轻负荷,使挖掘机的工作不致于中断,同时又能保护工作装置免于承受过大的机械应力。我厂生产的W-1002和W-1002A型电动挖 When working with a single-bucket excavator, the drive system is required to have a so-called “excavator characteristic”. When the work apparatus encounters a heavy load, the transmission speed can be automatically reduced significantly, enabling the driver to perceive it, thereby manipulating the excavator to reduce the load. The work of the excavator is not interrupted, and at the same time, the working device can be protected from excessive mechanical stress.
