ABSTRACT OF THE DISCLOSURE This invention is directed to a novel useful transit concrete mixer, the combination of a truck frame, forward steerable wheel means mounted on the truck frame, first rear wheel means mounted on the truck frame, a concrete mixer mounted on the truck frame, and means for transferring load away from the first rear wheel means, or the first rear wheel means and the forward steerable wheel means, and thereby increasing the load span of the transit concrete mixer, the load transfer means including a load transfer system having second rear wheel means, the second rear wheel means being pivotally mounted to the truck frame by pivot means carried by the truck frame and generally transversely horizontally axially disposed with respect to the longitudinal axis of the truck frame, and a pair of hydraulic cylinder means pivotally mounted on the truck frame, the pivot point between the truck frame and each of the pair of hydraulic cylinder means being located beneath the top of the truck frame, the reciprocating end of each of the pair of hydraulic cylinder means being connected to its associated portion of the second rear wheel means so as to pivot the second rear wheel means about its pivotal mounting, and control means for raising the second rear wheel means out of contact with the ground, lowering the second rear wheel means from a raised position to a ground contacting position, and loading the second rear wheel means while the second rear wheel means are in contact with the ground, whereby at least a portion of the load carried by the first rear wheel means, or the first rear wheel means and the forward steerable wheel means, is transferred to the second rear wheel means.
