Abstract

A stabilizer pad for use with stabilizer legs of a work machine is disclosed. The stabilizer pad may include a frame configured for attachment to the stabilizer leg of the work machine. The stabilizer pad may further include a first surface configured to contact a ground surface, the first surface including a resilient member, and the first surface extending a first distance from the frame in a first direction. Additionally, the stabilizer pad may include a second surface configured to contact a ground surface, the second surface including a plurality of rigid members, and the second surface extending a second distance from the frame in the first direction, the second distance being less than the first distance.

First claim

What is claimed is:

1. A stabilizer pad for a work machine, the stabilizer pad comprising:
a frame configured for attachment to a stabilizer leg of the work machine;
a first surface configured to contact a ground surface, the first surface including a resilient member having a resilient material overmolded to a resilient member plate such that the resilient member plate is entirely contained within the resilient material, the resilient member being attached to the frame by a fastener that extends in a first direction and is partially embedded within the resilient material and traverses the resilient member plate and the frame, and the first surface extending a first distance from the frame in the first direction; and
a second surface configured to contact and engage the ground surface when the resilient member is at least partially compressed, the second surface including a first plurality of rigid members extending toward the ground surface and positioned on a first side of the resilient member and a second plurality of rigid members extending toward the ground surface and positioned on a second side of the resilient member opposite to the first side, and wherein the second surface extends a second distance from the frame in the first direction, the second distance being less than the first distance,
wherein the frame includes a support plate that extends substantially parallel to the resilient member plate, wherein the first and second pluralities of rigid members extend from respective traction walls, and
wherein each of the traction walls includes an upper curved portion that is coupled to and extends away from the support plate of the frame, and wherein each of the traction walls includes a lower planar portion that extends away from the upper curved portion of the respective traction wall such that the pluralities of rigid members extend laterally beyond the resilient member to form a vertically-extending gap between the resilient member and the pluralities of rigid members.

2. The stabilizer pad of claim 1 , wherein the first surface comprises a plurality of resilient members, and wherein each resilient member of the plurality of resilient members is replaceable.

3. The stabilizer pad of claim 1 , wherein each of the first plurality of rigid members and the second plurality of rigid members are selected from a group consisting of grousers, spikes, blades, cleats, tracks, treads, grooves and traction providing members.

4. The stabilizer pad of claim 1 , wherein the resilient member defines a ground-contacting surface and an upper surface opposite therefrom, and the fastener extends through the upper surface.

5. The stabilizer pad of claim 1 , further including:
first and second flanges extending from first and second edges of a first side of the support plate and configured for attachment to a distal end of a stabilizer leg of the work machine such that the distal end of the stabilizer leg is spaced away from the first side of the support when attached to the stabilizer leg; and
a third flange extending from the first side of the support plate and positioned on a third edge of the first side of the support plate, wherein the third edge of the first side of the support plate is perpendicular to both the first edge and the second edge, wherein the third flange includes an opening therethrough, and wherein a fourth edge of the first side of the frame is free from a flange extending therefrom.

6. A stabilizer pad for a work machine, the stabilizer pad comprising:
a substantially planar support plate having a first side and a second side;
first and second flanges extending from opposite edges of the support plate first side and configured for attachment to a distal end of a stabilizer leg of the work machine such that the distal end of the stabilizer leg is spaced away from the first side of the support plate when attached to the stabilizer leg;
at least one resilient member extending in a first direction from the support plate second side and configured for contact with a paved surface, the resilient member including a resilient material overmolded to a resilient member plate such that the resilient member plate is entirely surrounded by the resilient material, and wherein the resilient member is attached to the support plate by a fastener that extends in the first direction through a segment of the resilient material and traverses the resilient member plate and the support plate;
first and second traction walls extending in the first direction, each traction wall having a distal edge that includes a plurality of rigid members configured for contact with an earth surface, wherein the first traction wall is coupled to the support plate via a first curved portion, and wherein the second traction wall is coupled to the support plate via a second curved portion; and
a third flange that extends from the support plate first side, the third flange including an opening there through, wherein the third flange is positioned on a third edge of the first side perpendicular to the first and second flanges, and wherein a fourth edge of the first side of the support plate is free from a flange extending therefrom.

7. The stabilizer pad of claim 6 , further comprising a plurality of resilient members.

8. The stabilizer pad of claim 6 , wherein the resilient member is replaceable.

9. The stabilizer pad of claim 6 , wherein the resilient member comprises polyurethane.

10. The stabilizer pad of claim 6 , wherein the plurality of rigid members comprises grousers.

11. The stabilizer pad of claim 6 , wherein the resilient member is at least partially disposed below the distal edges of the traction walls.

12. The stabilizer pad of claim 6 , wherein the rigid members are configured for contact with the earth surface only after at least partial compression of the resilient member.

13. The stabilizer pad of claim 6 , wherein the first and second flanges are further configured to receive bolt on attachments.

14. The stabilizer pad of claim 6 , wherein the resilient member includes an upper surface in facing relationship with the support plate second side, and the fastener extends through the upper surface.

15. The stabilizer pad of claim 6 , wherein the first traction wall includes a first straight portion that extends from the first curved portion to the plurality of rigid members, wherein the second traction wall includes a second straight portion that extends from the second curved portion to the plurality of rigid members, and wherein the first and second straight portions are spaced away from the at least one resilient member by first and second gaps.

16. A stabilizer pad for a work machine, the stabilizer pad comprising:
a frame;
a resilient member including:
a substantially planar resilient member plate; and
a resilient material overmolded to the resilient member plate such that the resilient member plate is positioned within the resilient material,

a fastener adapted to attach the resilient member to the frame of the stabilizer pad, the fastener extending between a first end and a second end and traversing the resilient member plate, the first end being positioned within the resilient material and the resilient member plate being positioned between the first end and the second end;
at least one traction wall, wherein the at least one traction wall includes an upper curved portion and a lower planar portion, wherein the upper curved portion is coupled to the frame and extends away from a side of the frame, wherein the lower planar portion extends at an angle away from the upper curved portion in a same dire
