Abstract: An air brake system for a truck in which various control valves controlling air supply to air sub-systems, parking and trailer brakes, and various brake system condition signal generators are mounted on a common manifold positioned remotely from the truck engine compartment and instrument panel, removing them from the instrument panel area and improving the plumbing arrangements for installation, diagnostics and servicing while clearing instrument panel space for other controls and devices which need the benign environment such as that in the truck cab provided for the truck driver. The system components may be used as needed for a straight truck or one composed of a tractor and trailer combination, or on a truck tractor adapted to tow a trailer.

Abstract: A structure for supporting a plurality of rows of batteries includes a frame having side rails and cross members releasably supported beneath the vehicle. Aligned pairs of I-type beams are cantilevered from the side rails of the frame. The lower flanges of parallel aligned pairs of beams underlie and support a respective edge of a row of batteries placed therebetween with the top flanges of the beams located below the upper edges of the batteries. The top flanges of the beams are narrower than would be necessary for an equivalent simple beam, thus maximizing the number of batteries containable in the available space.
