Abstract

A stabilizer pad including a pair of plate members supported from a stabilizer arm; and a pad assembly that is adapted for mounting between the pair of plate members. The pad assembly has a resilient pad having opposite ground engageable work surfaces and opposite support surfaces, and a plurality of support members extending from the opposite support surfaces of the resilient pad. The support members are each adapted for engagement with a receiving slot of one of the plate members for mounting of the pad assembly to the plate members. At least one retaining member extends through the resilient pad and between the plate members for holding the pad assembly to the plate members.

Claims

1. A resilient pad structure mounted from a support weldment comprising:

a unitary resilient pad having opposite ground engaging surfaces, one of which is adapted to be in a downwardly facing orientation for ground engagement;

a plurality of support posts extending from said resilient pad at spaced intervals and each engaged in a direction orthogonal to the ground engaging surface for mating with an accommodating open receiving slot disposed along a bottom edge of said weldment; and

at least one securing member that is connectable between said resilient pad and said weldment for holding said resilient pad to said weldment.

2. A stabilizer pad structure as set forth in claim 1 wherein said support posts extend from opposite sides of said resilient pad.

3. A stabilizer pad structure as set forth in claim 1 wherein said support posts are spaced along opposite support sides of said resilient pad and along a linear locus.

4. A stabilizer pad structure as set forth in claim 1 wherein said resilient pad has a plurality of passages therethrough, each for receiving an elongated support member, the opposite free ends of which form said support posts.

5. A stabilizer pad structure as set forth in claim 1 including an adaptor plate disposed between the resilient pad and weldment.

6. A stabilizer pad structure as set forth in claim 1 wherein said resilient pad is formed of pad sections of different hardness.

7. A stabilizer pad structure as set forth in claim 1 wherein said weldment has grouser points.

8. A resilient pad structure as set forth in claim 1 wherein said securing member comprises an elongated securing pin that extends through said resilient pad between spaced plate members of the weldment.

9. A resilient pad structure as set forth in claim 1 wherein each slot is non-circular.

10. A resilient pad structure as set forth in claim 1 wherein each slot has an open side which receives the post by sliding laterally into the open slot.

11. A resilient pad structure as set forth in claim 1 wherein said resilient pad is formed of a laminate of a plurality of resilient pad layers, and said support posts are formed by plural rods that are force-fit within passages of said resilient pad layers to maintain said layers together.

12. A resilient stabilizer pad comprising:

a resilient pad member having opposite ground engaging surfaces, one of which is adapted to be in a downwardly facing orientation for ground engagement, and having opposite support surfaces; and

a plurality of mounting lugs that are permanently affixed with said pad member including one lug set extending from one support surface side of said resilient pad member for releasable engagement with a corresponding open receiving slot set disposed along a bottom edge of one support plate of a weldment, and another lug set extending from an opposite support surface side of said resilient pad member for releasable engagement with a corresponding open receiving slot set disposed along a bottom edge of another support plate of a weldment.

13. A resilient stabilizer pad as set forth in claim 12 wherein said resilient pad has a plurality of passages therethrough, each for receiving an elongated support member, the opposite free ends of which form said support lugs, and wherein the elongated support members are fixed in said passages in both a mounted and dismounted position of said resilient pad.

14. A resilient stabilizer pad as set forth in claim 12 wherein said support lugs are spaced along opposite support sides of said resilient pad and along a linear locus.

15. A resilient stabilizer pad as set forth in claim 12 including a securing member that comprises an elongated securing pin that extends through said resilient pad between the support plates of the weldment.

16. A resilient stabilizer pad as set forth in claim 12 wherein each slot has an open side which receives the lug by sliding laterally into the open slot.

17. A resilient pad structure as set forth in claim 12 wherein said resilient pad is formed of a laminate of a plurality of resilient pad layers, and said mounting lugs are formed by plural rods that are force-fit within passages of said resilient pad layers to maintain said layers together.

18. A resilient pad structure for mounting from a support weldment at a series of slots in respective plate members of the weldment, said resilient pad structure comprising:

a resilient pad having opposite ground engagable surfaces, one at a time of which is adapted to be in a downwardly facing orientation for ground engagement while the other surface is out of ground engagement;

said resilient pad also having opposite support surfaces that are disposed generally transverse to said ground engagable surfaces;

said resilient pad further having respective mounted and dismounted positions relative to said weldment;

a plurality of support rods extending through said resilient pad and disposed in a pattern corresponding to and for engagement at respective ends thereof with said series of slots of said weidment;

said support rod ends extending beyond respective opposite support surfaces of said resilient pad for engagement with said slots;

each said plate member slot comprising an open receiving slot extending in the plane of said plate member at an edge thereof;

each said support rod end for mating engagement with an open receiving slot.

19. A resilient pad structure as set forth in claim 18 including at least one securing member that is connectable between said resilient pad and said weldment for holding said resilient pad to said weldment.

20. A resilient pad structure as set forth in claim 19 wherein said securing member comprises at least one retaining pin that extends through the resilient pad and a hole in each plate of the weldment.

21. A resilient pad structure as set forth in claim 18 wherein said resilient pad comprises a laminated pad including a plurality of resilient pad layers inter-engaged by at least said support rods to form a unitary resilient pad.

22. A resilient pad structure as set forth in claim 18 wherein said resilient pad comprises a molded pad having the support rods pass therethrough for support of said resilient pad.

23. A resilient pad structure as set forth in claim 18 wherein said support rods are force fit in accommodating holes in said resilient pad.

24. A resilient pad structure as set forth in claim 18 including a sleeve on each end of each said support rod.

25. A resilient pad structure as set forth in claim 18 wherein the support rod has a roughened surface to enhance engagement with the resilient pad.
