A dolly assembly for use in towing a disabled vehicle, preferably including a main tube with a dolly wheel mounted at each end, and a method of using same. In one preferred embodiment, the main tube is capable of selective expansion or contraction along its longitudinal axis, to facilitate adjustment and placement of dolly axle assemblies connecting opposed, generally parallel dolly assemblies. Force leveraging mechanisms may be used to aid the selective expansion or contraction of the main tube, such as ratchet or rack and pinion mechanisms. In an alternative embodiment, and for ease in transport, the dolly assembly may be pivotably collapsed along its main tube about either a vertical or horizontal axis.

We claim: 1. A towing dolly cradle assembly for use in towing a disabled vehicle, comprising: two opposed, generally parallel pairs of dolly assemblies, each dolly assembly comprising a main tube having a dolly wheel mounted at each end; two opposed dolly axles connecting the opposed dolly assemblies, each dolly assembly being designed to grip and lift a tire of the disabled vehicle; wherein the main tube is capable of selective expansion or contraction along its longitudinal axis, to facilitate adjustment and placement of the dolly axles relative to the tire of the disabled vehicle. 2. A towing dolly cradle assembly for use in towing a disabled vehicle, comprising: two opposed, generally parallel pairs of dolly assemblies, each dolly assembly comprising a main tube having a dolly wheel mounted at each end; two opposed dolly axles connecting the opposed dolly assemblies, each dolly assembly being designed to grip and lift a tire of the disabled vehicle; wherein the main tube has one or more cradles mounted on it, the one or more cradles each being adapted to attach to a dolly axle; wherein the one or more cradles are capable of selective sliding movement along the main tube. 3. The dolly assembly of claim 2, further comprising two pivot mounting assemblies located at opposing locations on the main tube, each pivot mounting assembly being pivotably mounted to a dolly wheel. 4. The dolly assembly of claim 3, wherein the one or more cradles are located on the main tube and between the pivot mounting assemblies. 5. A towing dolly cradle assembly, comprising: two opposed, generally parallel towing dolly assemblies, each dolly assembly comprising a main tube and two dolly wheels, wherein opposing pivot mounting assemblies are located at each end of the main tube, and two axle cradle assemblies are located along the main tube and between the pivot mounting assemblies, with each axle cradle assembly connecting a dolly assembly to a dolly wheel; and two dolly axle assemblies interposed between and connecting the two dolly assemblies; wherein each main tube is capable of selective expansion or contraction along its longitudinal axis. 6. The towing dolly cradle assembly of claim 5, wherein each main tube carries one or more cradles, the one or more cradles each being adapted to attach to an axle assembly connecting two opposing dolly assemblies, and wherein the one or more cradles are capable of selective sliding movement along the main tube.
