A supporting device includes a tray, a plurality of wheel assemblies, a handle, and a handgrip. The tray is configured for supporting a payload. The wheel assemblies are secured to the tray, and each wheel assembly includes a wheel. Each wheel is capable of rotating about a first axis. The wheel assemblies are rotatable between a first position and a second position, and a distance between each wheel and the tray in the first position is smaller than a distance between each wheel and the tray in the second position. The handle is attached to the tray and configured to urge the wheel assemblies to rotate from the first position to the second position. The handgrip is attached to the tray and configured to urge the wheel assemblies to rotate from the second position to the first position.
