Abstract

The invention pertains to a self-contained, mobile, pavement repair apparatus. A self-propelled, wheeled vehicle is described, upon which are mounted a material supply hopper, a debris storage, an overhead crane arm, and an articulated conveyor arm. Mounted on the business end of the crane arm are various implements for performing pavement repair, all of which are remotely controlled by a single user in an enclosed cab. Asphalt or concrete patching material is transported by an auger from the tiltable supply hopper to an articulated conveyor arm, which conveyor arm deposits the material upon the repair area. The user remotely controls the overhead crane arm in order to position and actuate, from the cab, the various repair implements. All apparatus functions, materials and safety devices necessary to complete the repair process may be operated by a single user.

Claims

1. An apparatus for repairing an area of pavement comprising:

means comprising a wheeled chassis;

means comprising an articulated crane upon said chassis;

means for storing materials on said chassis; and

means for transporting said materials from said storing means to the pavement area to be repaired.

2. The apparatus of claim 1 wherein said means comprising an articulated crane further comprises means for rotatably attaching said articulated crane to said chassis.

3. The apparatus of claim 1 wherein said means comprising an articulated crane further comprises vertical section means and horizontal section means.

4. The apparatus of claim 3 wherein said means comprising an articulated crane further comprises pivotal connection means thereby permitting relative vertical movement between said vertical section means, said horizontal section means, and said chassis.

5. The apparatus of claim 3 wherein said horizontal section means further comprises means for extending and retracting said horizontal section means.

6. The apparatus of claim 3 wherein said vertical section means further comprises a plurality of pavement repair implements.

7. The apparatus of claim 6 wherein said plurality of pavement repair implements further comprise means for reciprocating said plurality of pavement repair implements.

8. The apparatus of claim 6 wherein said plurality of pavement repair implements comprises at least one jackhammer.

9. The apparatus of claim 6 wherein said plurality of pavement repair implements further comprises at least one compactor.

10. The apparatus of claim 6 wherein said plurality of pavement repair implements further comprises at least one multi-headed torch.

11. The apparatus of claim 6 wherein said plurality of pavement repair implements further comprises at least one sprayer.

12. The apparatus of claim 6 wherein said plurality of pavement repair implements further comprises at least one vacuum head.

13. The apparatus of claim 6 wherein said plurality of pavement repair implements further comprises at least one scarifier means.

14. The apparatus of claim 1 wherein said means for storing materials further comprises means for storing pavement repair materials and detritus.

15. The apparatus of claim 14 wherein said means for storing pavement repair materials comprises controllably tiltable hopper means.

16. The apparatus of claim 15 wherein said means for storing pavement repair materials further comprises heating means.

17. The apparatus of claim 1 wherein said means for transporting materials comprises a plurality of conveyor means for transporting pavement repair materials to the pavement area to be repaired.

18. The apparatus of claim 17 wherein at least one of said plurality of conveyor means comprises auger means.

19. The apparatus of claim 17 wherein at least one of said conveyor means comprises horizontally pivotable conveyor means.

20. The apparatus of claim 1 further comprising:

means for containing debris on said chassis; and

means for transporting the debris from the pavement area to be repaired to said containing means.

21. The apparatus of claim 20 wherein said debris transporting means comprises vacuum means for transporting debris from the pavement area to be repaired.

31. The method of claim 21 wherein the step of transporting the materials further comprises the step of providing a plurality of conveyors for transporting pavement repair material to the pavement area to be repaired.

32. The method of claim 31, wherein the step of providing a plurality of conveyors further comprises the step of providing at least one auger.

33. The method of claim 31 wherein the step of providing a plurality of conveyors further comprises the step of horizontally pivoting at least one conveyor.

22. A method of repairing an area of pavement comprising the steps of:

(a) providing a wheeled chassis;

(b) mounting an articulated crane on the chassis;

(c) storing materials on the chassis; and

(d) transporting the materials from storage on the chassis to the pavement area to be repaired.

23. The method of claim 22 wherein the step of mounting an articulated crane on the chassis further comprises the step of rotatably attaching the articulated crane to the chassis.

24. The method of claim 23 wherein the step of mounting an articulated crane on the chassis further comprises the step of pivotably connecting a vertical crane section, a horizontal crane section and the chassis.

25. The method of claim 22 wherein the step of pivotably connecting a vertical crane section, a horizontal crane section and the chassis further comprises the step of extending and retracting the horizontal crane section.

26. The method of claim 24 wherein the step of pivotably connecting the vertical crane section, a horizontal crane section and the chassis further comprises the step of mounting a plurality of pavement repair implements on the vertical crane section.

27. The method of claim 26 wherein the step of mounting a plurality of pavement repair implements on the vertical crane section further comprises the step of reciprocating the plurality of pavement repair implements.

28. The method of claim 22 wherein the step of storing materials on the chassis further comprises the step of storing pavement repair materials and detritus.

29. The method of claim 28 wherein the step of storing pavement repair materials further comprises the step of controllably tilting a hopper.

30. The method of claim 28 wherein the step of storing pavement repair materials further comprises the step of heating the pavement repair materials.

34. The method of claim 22 further comprising the steps of:

(a) placing a debris container upon the chassis; and

(b) transporting debris from the pavement area to be repaired to the container on the chassis.

35. The method of claim 34 wherein the step of transporting debris comprises the step of vacuuming debris from the pavement area to be repaired.
