The subject invention is a lightweight, foldable, collapsible dolly which is to be used to move exterior heavy objects from one locale to another that is capable of being folded to a substantially shortened, flat arrangement facilitating storage in confined quarter locations such as beneath the seat or within an overhead bin of an airplane or train. The collapsible dolly includes a pair of wheels, each of which is movable from the flat arrangement to a transverse position relative to the support frame of the collapsible dolly. With the wheels located in the flat arrangement, the dolly can be rolled by the wheels on a supporting surface. The moving of the wheels into the transverse position occurs automatically during movement of the platform from its stowage position to an outwardly extended position which is the loading position of the platform. A handle unit is to be extendable from the support frame by the actuation of a single actuation device which then permits the handle unit to be moved to extended positions. With the handle unit in any position, the dolly is conveniently wheelable by a human when either in the collapsed or using position.
