A vehicle carrier with wheel lifting apparatus for a truck having an underframe and consisting of a channel 21 having ledges 22 along an opening of the channel for partially enclosing the channel, the channel mounted to the underframe of the truck between a forward mount and a tail mount, a base 23 being slidably received within the channel and being movably carried on the ledges, subtending arm 40 pivotally mounted to the base 23 at one end and secured at the other end to a rearwardly disposed housing 47, telescoping member assembly 45 mounted within the housing 47 for retracting or extending the telescoping member assembly 45, the end member of which terminates at a pivot, transverse member 61 extending laterally in opposite directions from the pivot, wheel supports mounted on the transverse member for selectively engaging and disengaging vehicular wheels from the wheel supports, first hydraulic means connectively extending between the tail mount 19 and the base 23, second hydraulic means connectively extending between the tail mount and the housing, third hydraulic means connectively extending between the housing and the pivot of the telescopic member assembly, fourth hydraulic means on the lateral or transverse member connectively extending between the pivot to each of the ends thereof for enabling selective engagement and disengagement of the wheel supports with the behicular wheels, and each of the first to the fourth hydraulic means cooperatively operable to effect the wheel lifting apparatus. An obtuse angle of greater than 163 DEG is distended between a longitudinal axis of the arm and the horizontal surface of the housing.
