^{Routine maintenance of transport vehicle}

^{There are two conditions for the display of electric flat car without power supply, the first is not powered on. In this case, the test pencil shall be used to check whether the circuit is in the path state and whether the power line is loose or falling off. The second is that the voltage is too low: when the voltage of the electric transfer vehicle is more than 10% lower than the rated voltage, the tram protection system will start undervoltage protection to turn off the power supply. At this time, it is necessary to stop the work, turn off the power supply and turn it on again.}

^{If the temperature of the electric flat car is too high or the electric flat car is heated due to overload, it will also cause the carrier to not work during use. Long term overload will burn the electric flat car, so the flat car load must be within the rated load range.}

^{When the electric flat car manufacturer transports heavy objects, it cannot be started after stopping: the system voltage is too low or fluctuates too much: it can be started after the electric flat car voltage returns to normal.}

^{Under normal circumstances, replace the grease every six months. When replacing grease, first clean the bearing with kerosene or gasoline, and then fill two-thirds of the bearing chamber with grease. Too much or too little is unfavorable for lubrication. The motor shall be overhauled regularly, usually once every three months and once a year. If the motor winding is burned due to accident, it shall be disassembled in time to analyze the cause. Usually, the secondary winding is burnt out due to starting switching failure or capacitor short circuit; The main winding is burnt out due to long-term overload or startup locked rotor. Replace the motor winding and eliminate the accident before reuse.}

^{Maintenance of transfer trolley}

^{When the power of the charging battery of the moving truck is insufficient, it should be charged immediately. If there is a spare battery, it can be replaced with a spare battery to continue working.}

^{Battery replacement and battery charging work is to be responsible for the actual operation of the staff must be disconnected from the switching power supply.}

^{If the battery is charged for too long, the temperature of the battery will rise and the service life of the battery will be shortened.}

^{In order to avoid burning the motor of trackless electric flat car or causing other common faults, it is strictly prohibited to exceed the standard and overload application of machinery and equipment.}

^{When using the equipment to transport the suspended objects, place them stably and ensure the weight is evenly distributed.}

^{At the same time, we should always check the work situation everywhere. Once we find that the temperature of the motor and rolling bearing of the electric flat car is rising or abnormal sound, we should stop and check it immediately.}

^{The battery charger can be fully charged according to the working capacity of the charging battery, without opening the charging battery cover, which is not easy to strong and overcharge. When charging the battery, special attention should be paid to the indication of the light. If the normal battery charging can not be notified to the relevant technical personnel for maintenance.}
