KPT series towing electric transfer trolley running time depends on flat mop the floor by cable power supply. One end of the cable on ground power supply, the other end by the electricTransfer Trolley  iron clamp device is introduced into flat vehicle.The characteristics is height is low, easy loading and unloading heavy empty, but running distance is not too long, generally no more than 100 m, it is too long for coil cable.

KPX series is battery powered Transfer Trolley. Battery supply power is the DC traction motor, Compared with the DC motor and AC motor is not easy to burn out, starting torque, the advantages of the overload capacity is strong. It is safer than KPJ, KPD two series Transfer Trolleys, it is more flexibility to over bend, rail,and the running distance is not restricted, no insulation requirements in rails.
