Abstract: A tow truck carrier with sub frame rails above the carrier chassis frame rails that also reduces platform height thereby presenting a lower center of gravity. Sub frame rails of rectangular steel tubing with the wider dimension of the tubing are used in a horizontal, low profile orientation, with the direct attachment of the lift cylinder ends to the sub frame rails or to a cross beam to lower the platform. The sub frame rails form a descending ladder frame with cross members attached via brackets so that they are lowered into the recess between the chassis side frame. A lifting bracket is welded to the underside of each sub frame rail underneath the overhang and adjacent to the chassis frame to accept the end of a lifting cylinder rod while leaving some space for sliding engagement of a platform beam which engages three edges of the sub frame rail.
