Claim:
1. A wheel lifting device comprising: a first arm comprising a first upper member and a first lower member, the first lower member extending downward from the first upper member; a second arm comprising a second upper member and a second lower member, the second lower member extending downward from the second upper member, the second upper member pivotally connected to the first upper member in a scissors arrangement so that the first lower member and the second lower member are spaced apart to receive at least a portion of a wheel assembly there between; a first wheel support assembly coupled to the first lower member, the first wheel support assembly comprising a first cross member extending from the first lower member, a first roller assembly coupled to the first cross member, and a second roller assembly coupled to the first cross member, the first and second roller assemblies spaced apart along the first cross member and configured to bear on a cylindrical inner surface of a rim of the wheel assembly at corresponding spaced apart points along a first side of the wheel assembly when the wheel assembly is lifted; and a second wheel support assembly coupled to the second lower member, the second wheel support assembly comprising a second cross member extending from the second lower member, a third roller assembly coupled to the second cross member, and a fourth roller assembly coupled to the second cross member, the third and fourth roller assemblies spaced apart along the second cross member to bear on the cylindrical inner surface of the rim at two corresponding spaced apart points along a second side of the wheel assembly when the wheel assembly is lifted; wherein the first, second, third, and fourth roller assemblies are configured to rotate to facilitate rotation of the wheel assembly.
