某型号平地机反馈不能行走的故障,针对动力、传动、电器系统等可能引发故障点进行原因分析,确定故障由电器系统引起,并给出解决方案。该型号平地机驻车制动采用软轴手刹模式。根据手制动原理,通过简易流程图查找电气线路的故障。经过排查,找到整机不能行走的原因在于手制动开关出现故障,需要更换手制动开关。该型号平地机更换手制动开关后恢复正常行走。
Some models of graders feedback can not walk the fault, for power, transmission, electrical systems and other possible causes of failure point analysis to determine the fault caused by the electrical system and gives solutions. The model grader parking brake using flexible shaft handbrake mode. According to the principle of hand brake, through simple flow chart to find fault of the electrical circuit. After investigation, find the machine can not walk because of the hand brake switch failure, the need to replace the hand brake switch. This model grader to replace the hand brake switch back to normal after walking.
