Abstract

A materials transport container having a floor and two opposed upwardly extending side walls and a front wall. The container is supported to enable tilting for unloading of material from a rear end. The container has a substantially continuous and smooth hard faced surface on a rear portion of the floor adjacent the rear end to enhance sliding of its load over the smooth hard faced surface. Additionally arcuate surfaces bridging a junction between one or more of the front and side walls and the floor of the container to reduce hangup of material. The arcuate surfaces are smooth hard faced surfaces. The hard faced surfaces are provided by removable wear plates with gaps between then to allow flexion and ease of removal. It is found with use these hard faced wear plates become polished and greatly assist with the removal of material from the transport container.

Claims

1. A dump truck body having a floor and two opposed side walls and a front wall, said walls extending upwardly from the floor, the body further having an unloading end, the body being supported to enable tilting for unloading of material from the unloading end,

the body comprising a plurality of hard faced wear plates providing a substantially continuous and smooth hard faced sliding surface on an unloading portion of the floor adjacent the unloading end, so as to enhance the sliding of material over the smooth hard faced sliding surface, the wear plates comprising a layer of hard surfacing alloy, over a mild steel base, a surface of the alloy finished to form the hard faced sliding surface,

there being provided one or more curved, arcuate surfaces bridging a junction between one or more of the front and side walls and the floor of the body to reduce hangup of material thereon.

2. A dump truck body as in claim 1 wherein the one or more curved, arcuate surfaces comprise one or more arcuate hard faced wear plates each having a layer of hard surfacing alloy over a mild steel base, a surface of the alloy of the arcuate wear plate being finished to form an arcuate smooth hard faced surface.

3. A dump truck body as in claim 2 wherein one of the one or more curved, arcuate surfaces bridges a junction between the front wall and the floor of the body.

4. A dump truck body as in claim 2 wherein one of the one or more curved, arcuate surfaces bridges a junction between the front wall and the floor of the body, and two other ones of said one or more curved, arcuate surfaces bridge joints between the opposed side walls and the floor on either side of the unloading portion of the floor.

5. A dump truck body as in claim 2 wherein one of the one or more curved, arcuate surfaces bridges a junction between the front wall and the floor of the body, and two other ones of said curved, arcuate surfaces bridge joints between the opposed side walls and the floor on either side of the floor, and extending along the length of the floor.

6. A dump truck body as in claim 1 wherein the smooth hard faced sliding surface is provided by a liner fastened to the dump truck body.

7. A dump truck body as in claim 6 wherein the liner is provided by a plurality of said wear plates.

8. A dump truck body as in claim 7 wherein said wear plates are spaced apart to allow for flexion between adjacent ones of said wear plates.

9. A dump truck body as in claim 7 wherein a gap between adjacent ones of said wear plates is less than 20% of a width of the adjacent ones of said wear plates.

10. A dump truck body as in claim 9 wherein the gap is about 25 mm.

11. A dump truck body as in claim 2 wherein a radius of the one or more curved, arcuate surfaces is greater than about 250 mm.

12. A dump truck body as in claim 2 wherein a minimum radius of the one or more curved, arcuate surfaces is about 300 mm.

13. A dump truck body as in claim 6 wherein the mild steel base is between 5 and 11 mm in thickness.

14. A dump truck body as in claim 1 wherein the hard surfacing alloy is a carbide containing alloy, with primary and secondary carbides in an alloy matrix.

15. A dump truck body as in claim 1 wherein the hard faced sliding surface has a Brinell hardness of 500.

16. A dump truck body as in claim 13 wherein the thickness of the alloy is between 6 and 12 mm.

17. A dump truck body as in claim 2 wherein the arcuate surfaces are provided by a liner fastened to the body.

18. A dump truck body as in claim 1 wherein said one or more curved, arcuate surfaces are provided by a liner fastened to the dump truck body.

19. A dump truck body as in claim 1 wherein the unloading portion of the floor with a hard faced surface is about 0.5 meters taken from the unloading end of the floor.

20. A dump truck body as in claim 1 wherein the unloading portion of the floor with a hard faced surface is about 1 meter taken from the unloading end of the floor.

21. A dump truck body as in claim 1 wherein the unloading portion of the floor with a hard faced surface is about one third of the floor taken from the unloading end of the body.
