ABSTRACT:
A highway semitrailer body converts for transporting either discrete or loose bulk cargo by either maintaining hinged slope sheets in the ends of the body latched up near the roof or inclining them down to form a continuation of the hoppers in the floor. A grating over the hoppers supports the discrete cargo or permits loose bulk cargo to pass through its openings. The slope sheets are raised and lowered by flexible belt hoists actuated from outside the body through chain and sprocket transmissions mounted under covers between pairs of vertical ribs. The slope sheets are released from their upwardly latched positions by pull rod linkages also mounted between the pairs of vertical ribs. The bottom ends of the slope sheets are firmly clamped against the floor grating by locking pawls which hold down hooks on the bottom ends of the slope sheets, which pass through spaces in the grating.
