1. Electricity shortage. The electric transfer vehicle is equipped with a battery, which needs to be charged after use. When we use the equipment, we need to check whether the voltage of the battery is low and whether the power of the battery is satisfactory. When the power is short, we need to Charge in time.

2. Lack of drive accessories. Check whether the switch and circuit of the electric transfer vehicle are loose, or there is a short circuit problem. Check whether the switch is damaged. It is necessary to repair the short circuit in time and replace the defective switch accessories. Pay attention to check whether the touch device of the device is burned out or the coil is short-circuited. Poor touch conditions cause the equipment to drive slowly and new contactor accessories need to be replaced in time. Check whether the drive motor is burnt, short-circuited or poorly touched, resulting in the failure of the device to obtain power.

3. Severe carbon brush wear: Severe carbon brush wear will increase the friction force during trekking and the touch area with the ground will become larger, which will slow down the trekking speed of the electric pallet trucks. New carbon brushes need to be replaced in time. Pay attention to regularly check the carbon brush wear everyday when driving.
