Abstract: A trailer wall construction having reduced weight. A trailer wall construction includes a spherical shaped corner at a juncture of three walls. Each of the walls includes at least one panel having spaced apart inner and outer shells. Another trailer wall construction includes a generally vertically extending front or side wall and a floor. The floor and front or side wall each includes at least one panel comprising spaced apart inner and outer shells. A curved connector connects a lower edge of the front or side wall to an edge of the floor. Yet another trailer wall construction includes a wall with panels attached to one another along opposing edges of the panels, each of the panels including spaced apart inner and outer shells. One connector is attached to each of the panels along a third edge. Another connector is attached to each of the panels along a fourth edge.

Abstract: A belly dump trailer including a hopper having sides made up of multiple hollow extruded aluminum panels. Cones are attached at forward and rearward ends of the hopper. The cones are made of aluminum. The cones are hollow and each cone includes internal stiffener rings supporting an outer shell. The hopper sides include top, side and bottom rails interconnected to the panels. Each of the top, side and bottom rails is made of a hollow extruded aluminum. Another belly dump trailer includes a hopper and a cone attached to the hopper, the cone having an axis which is inclined downwardly in a direction away from the hopper. Another belly dump trailer includes a hopper having first and second side walls each made up of multiple hollow panels, and front and rear walls; a first cone attached to the front wall; and a second cone attached to the rear wall.

Abstract: A trailer having a double wall extruded panel nose construction. A trailer wall construction for use as part of a trailer assembly includes a curved front wall including at least one curved panel having spaced apart inner and outer shells. Another trailer wall construction includes a series of elongated panels joined to each other along respective adjacent edges, each of the panels being curved and having spaced apart inner and outer shells. The joined panels form a curved wall of the trailer assembly.

Abstract: A trailer having sides with a combination of extruded panel and sheet material. A trailer wall construction for use as part of a trailer assembly includes at least one panel comprising spaced apart inner and outer shells, and at least one sheet. An edge of the sheet is attached to an edge of the panel. Another trailer wall construction includes a vertical side having a lower portion with spaced apart inner and outer shells, and an upper portion with only a single sheet thickness.
