Disclosed is a payload transportation device for transporting a payload, which has a low height and in which driving wheels are configured to come into constant contact with a ground surface even when the ground surface is uneven. The payload transportation device includes a loading plate above which a payload is loaded, a lift-driving portion configured to generate a driving force to vertically lift the loading plate, a first assembly configured to support a bottom of one side of the loading plate and in which some components included in the lift-driving portion are provided, a second assembly configured to support a bottom of the other side of the loading plate and in which other components included in the lift-driving portion are provided, hinge portions configured to connect the first assembly to the second assembly in a hinge structure, at least a pair of driving wheels coupled to both sides of a bottom of any one of the first assembly and the second assembly, and a driving unit configured to rotate the driving wheels.
