一台DCE80-100E型集装箱空箱堆高机在使用过程中会偶尔出现自动起升、侧移及倾斜的动作失控故障。该机起升、侧移及倾斜动作均由液压缸推动执行,其液压控制回路采用的是电液比例控制阀。根据以往的维修经验,首先应查找液压控制回路或电气控制回路故障。当该故障出现时,分别拔去控制起升、侧移及倾斜的电
A DCE80-100E Container Empty Container Stacker Occasionally there will be occasional automatic lifting, side-shifting and tilting out of control faults during use. The aircraft hoisting, lateral displacement and tilting movements are pushed by the hydraulic cylinder implementation, the hydraulic control circuit is electro-hydraulic proportional control valve. According to the previous maintenance experience, we should first find the hydraulic control circuit or electrical control circuit failure. When the fault occurs, unplug the lift control, lateral displacement and tilt of the electricity
