Abstract
Abstract A pad structure of generally circular configuration for attachment to the stabilizing outriggers of a vehicle such as a backhoe. The structure includes a base and peripheral side wall covered with rubber. Each pad structure is mounted to its associated outrigger by a ball joint which allows the pad to rotate and also to conform to the grade of the supporting surface. The pad is resistant to wear because of the rubber material, because of its configuration, and because of its capacity for rotation. Instead of dragging and digging into the supporting surface and adjacent structures, such as curbs and the like, it moves and thereby continually presents new wearing surfaces. Other features include means enabling ready removal and replacement of worn pads.

Total Claims: 6
Claim 1
Independent Claim
129 words
In a vehicle having a plurality of outriggers to support and stabilize the vehicle during the intervals when the vehicle is stationary between progressive advancements of the vehicle along a predetermined work path, an improved outrigger pad structure on each of said outriggers comprising: a foot including a generally circular base and a generally cylindrical peripheral wall, said wall having a multiplicity of surface protrusions; a resilient pad fitted over and bonded to said base and said wall and anchored in position on said wall by said surface protrusions; and ball joint means connecting said foot to the outrigger and operative to permit said foot to pivotally conform to the grade of the supporting surface, and further operative to permit said foot to rotate about a generally vertical axis.
