Abstract
A vehicle mounted automobile "wheel lift" towing mechanism having a power actuated lift boom vertically movable between raised and lowered positions along angularly inclined parallel tracks having cam members operable to impart predetermined vertical tilting movements to the boom; the latter at ground engagement being tiltable to conform to variations in ground slope; power actuation of the boom being responsive to extension and contraction of a horizontal lift cylinder assembly having a linearly movable piston. Manually operable wheel engaging apparatus, is carried by the lift boom for positively coupling a pair of vehicle wheels to the towing mechanism and includes a pair of pivotally movable wheel restraints operable to swing arcuately about vertical axes from positions laterally outwardly of adjacently opposed vehicle wheels to positions behind such wheels for restraining the latter against opposing wheel chocks.
