Abstract
A towing apparatus of the wheel lift variety is provided with wheel support members that move horizontally or vertically relative to a fixed-position support beam. The support members are mounted to the beam by pivotable, tapered collars and include a depending retainer that has both an extended height and depth to contact a substantial portion of the wheel circumference. The apparatus also provides means for rotating the support beam both above the below the horizontal. All of these features facilitate use of the towing apparatus.
