Embodiment Construction

[0012] Throughout the following detailed description, the same reference numerals refer to the same elements in all figures. Referring to FIG. 1, a flat bed trailer 10 has a front portion 12 attachable by standard methods with a wheel pin 82 to a truck cab. The trailer has a rear portion 14 and a right 16 and left 18 side portion. A top surface 20 has a width of about seventy-eight inches. Beams 22 and 24 are axially mounted to the undercarriage 26 of the flat bed trailer 10, usually by welding to the undercarriage. Alternatively, the beams can be bolted to the undercarriage 26. A portion of each beam 22 and 24 extends outwardly and upwardly from the right 16 and left 18 side of the trailer 10.

[0013] Referring to FIG. 3, beam 22 is welded to undercarriage 26. The beam 22 is a two piece construction having a maximum width from end 28 to end 30 of 102 inches. Approximately 24 inches of each end portion of beam 22 projects outwardly and upwardly at an angle of about ten degrees from t...

Abstract

A pair of opposed A-frames are positioned uprightly on a flat bed chassis. A downwardly descending side leg on each side of each A-frame rests on an axially mounted beam. The beam is attached to the underside of the flat bed chassis and extends outwardly from a side surface of the flat bed trailer and is angled upwardly to support a bottom edge of a building material slab or sheet.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to shipping support apparatus mounted on a flat bed trailer. More particularly, it refers to pairs of A-frames mounted on a flat bed trailer for supporting heavy upright loads. [0002] Currently, most heavy loads such as concrete slabs are transported on flat bed trailers by laying them down on the trailer top surface. Glass sheets have been transported in an upright position, secured to shipping racks as seen in U.S. Pat. No. 3,955,676. Sheet supporting racks have been used inside trailers as shown by U.S. Pat. No. 4,273,485 and U.S. Pat. No. 4,527,826. Flat bed trailers of differing configuration for supporting loads have been described in U.S. Pat. Nos. 4,626,017; 4,688,976; and 5,209,540. Although these references describe useful methods of carrying upright loads they do not provide a device for easily loading and unloading building materials constituting heavy loads. Such a device is needed to not only provide easy loadin...
