The invention provides a traction-type electric platform trolley capable of automatic following. The traction-type electric platform trolley comprises a trolley body. A traction device, a trolley tail hook and a microcontroller are installed on the trolley body. The traction device comprises a traction base. A rotating shaft which can rotate around the axis is vertically installed on the traction base. A first angle sensor is installed between the rotating shaft and the traction base. A hollow traction pulling rod is arranged at the top of the rotating shaft. One end of the traction pulling rod is connected with the rotating shaft through a pin shaft and the traction pulling rod can swing up and down around the pin shaft. A second angle sensor is installed between the rotating shaft and the traction pulling rod. A spring is arranged in the traction pulling rod. The connecting end of the traction pulling rod and the rotating shaft is provided with a tension sensor. The tension sensor is connected with one end of the spring. The microcontroller is connected with the angle sensors, the tension sensor, a storage battery, a motor speed adjuster, a steering gear and a parking braking device. The motor speed adjuster is connected with a motor. In the carrying process of the electric platform trolley, disassembling and maintaining are convenient, the manufacturing cost is low, the power is provided without labor, and one person can easily control multiple electric platform trolleys to carry heavy objects.
