Transporting device with panel truck

A transporting device, comprising:

• a container;
• a panel member having a plate and two first linkages, wherein ends of the first linkages are pivoted on the plate and on opposite lateral sides of the container respectively to be moved between a collapsed position, in which the plate is attached on the container, and an expanded position, in which the plate is moved apart from the container;
• a wheel frame having two second linkages and a stop member, wherein ends of the second linkages are pivoted on mid sections of the first linkages respectively and the stop member is fixed on the second linkage to sustain the plate while the panel member is moved to the expanded position;
• two wheels mounted on the second linkages respectively for free rotation, and
• a front wheel at a bottom side of the container for free rotation;
• wherein the wheels are moved to the lateral sides of the container respectively via the second linkages while the panel member is moved to the collapsed position and the wheels are moved apart from the container via the second linkages while the panel member is moved to the expanded position.
