The invention discloses an automatic lifting carrier truck. The automatic lifting carrier truck comprises a supporting frame (2) provided with moving mechanisms (1), a lifting frame (3) mounted on thesupporting frame (2), a traction mechanism for driving the lifting frame (3) to move upwards or downwards, a bearing mechanism (5) arranged on the lifting frame (3) and a control system. The tractionmechanism comprises two first motors (41) provided with frequency converters, driving wheels (42) mounted on the left and right sides of the supporting frame (2) and inhaul cable assemblies connectedwith the driving wheels (42) and the lifting frame (3). Each driving wheel (42) is in power connection with the output end of the corresponding first motor (41) through a coupler (44). The output endof each first motor (41) is provided with a first encoder. The safety, controllability and precision of the automatic lifting carrier truck provided by the invention are greatly improved. The automatic lifting carrier truck is higher in automation degree and greatly improves the working efficiency.
