Abstract

A compaction roller particularly useful for vibration compaction of the shoulder area of roadways. The compactor is designed as an attachment for side-mounting to self-propelled or motorized machinery (e.g. a skid steer front loader). The compaction roller contains: (a) a front section comprising a frame connected to a front cylindrical roller; (b) a rear section comprising a frame connected to a rear cylindrical roller; (c) a joining means pivotally connecting said front and rear sections; and (d) a means for attaching to a self-propelled machinery in a side-mounted fashion. The pivoting compactor allows for simultaneous pinching and compacting on two different planes and reduces the hazards of operating a road roller compactor directly on a sloped surface.

Claims

1. A compaction roller attachment for side-mounting to self-propelled machinery, said compaction roller attachment comprising:

a) a front section comprising a frame connected to a front cylindrical roller;

b) a rear section comprising a frame connected to a rear cylindrical roller;

c) a joining means pivotally connecting said front and rear sections; and

d) an attachment means for attaching the compaction roller to self propelled machinery.

2. The compaction roller according to claim 1 wherein one or both of the rollers are vibratory rollers.

3. The compaction roller according to claim 2 wherein only the rear roller is a vibratory roller.

4. The compaction roller according to claim 1 wherein said front section contains a single roller having a width that is smaller than the width of the rear roller.

5. The compaction roller according to claim 4 wherein the width of the front roller is about half the width of the rear roller.

6. The compaction roller according to claim 4 wherein said rollers each have left and right ends and wherein the front roller is positioned in an offset manner such that either the left or right ends of the rollers lie in the same plane when the compaction roller is on a level surface.

7. The compaction roller according to claim 1 additionally comprising transport hooks on said front and rear sections.

8. The compaction roller according to claim 1 wherein the joining means allows the rear section to freely rotate about an axis that is generally parallel to the direction of travel.

9. The compaction roller according to claim 1 wherein the attachment means comprises a connector shaft that is generally parallel with the axis of the front drum.

10. The compaction roller according to claim 9 wherein the attachment means is rigidly fixed to the front frame and is capable of receiving an attachment arm for connecting to a self-propelled or motorized vehicle.

11. The compaction roller according to claim 1 additionally comprising a rear stabilizer bar that connects the rear frame to the self-propelled machinery.

12. The compaction roller according to claim 1 additionally comprising a means for hydraulically determining the degree of rotation of the rear section.

13. A process of compacting a shoulder area of a roadway or other earthen surface comprising:

a) connecting a non-propelled compaction roller generally to the side of a self-propelled machinery so that it is in a side-mounted configuration; and

b) driving said self-propelled machinery with the side-mounted compaction roller on the main surface of the roadway in a manner that causes the side-mounted compaction roller to compact the roadway shoulder while the self-propelled machinery remains on the roadway.

14. The process according to claim 13 wherein the self-propelled machinery is a skid steer, a backhoe, an industrial tractor, a farm tractor, a grader, a pickup truck, a wheel loader, a dump truck, or a rubber-tracked bull dozer.

15. The process according to claim 14 wherein the self-propelled machinery is a skid steer.

16. The process according to claim 13 wherein two non-parallel surfaces are compacted simultaneously.

17. The process according to claim 16 wherein the compaction roller has a front drum and a rear drum and wherein the front drum pinches the seem between the roadway and the shoulder and the rear drum compacts the shoulder.
