Wheel dolly

A wheel dolly for raising a vehicle wheel off a floor or a horizontal surface by operation of an external jack that provides force in a direction orthogonal to the floor or horizontal surface the dolly comprising:

• at least two wheel straddle bars, each straddle bar having a non-swing caster assembly;
• a swing caster assembly connected to each straddle bar, the swing caster assembly comprising:
• a stationary frame supporting a swing axle;
• a swing frame constructed to rotate about the swing axle;
• and
• a swing caster connected to the swing frame, the swing caster defining a swivel plane;
• and
• a lift bar connecting the two wheel straddle bars that is capable of being lifted through contact with the external jack;
• wherein the wheel dolly can transition between two configurations:
• a lowered configuration, wherein the swivel plane is not parallel to the floor;
• a raised configuration, wherein the swivel plane is substantially parallel to the floor, and a portion of the straddle bars contacts the vehicle wheel;
• and wherein the transition between the lowered configuration, and the raised configuration is achieved by the operation of the external jack to raise the lift bar.
