Gripping device for articulated work machine

1. A work machine comprising:

a pivotable arm having a first gripping device formed within an edge of a side plate that extends beyond a bottom plate, the arm operatively connected to an attachment for securing an object between the first gripping device and the attachment; and

a second gripping device removably securable to the arm near the first gripping device, the second gripping device configured to extend beyond a bottom of the pivotable arm at least as far as the first gripping device in a direction generally perpendicular to the arm for at least partially securing an object between the second gripping device and the attachment, wherein the first gripping device includes a first gripping feature and the second gripping device includes a second gripping feature,

wherein the first gripping feature is different than the second gripping feature.

2. The machine of claim 1 , wherein the first gripping feature is shaped and positioned substantially similar to the second gripping feature such that the first and second gripping features are positioned to grip jointly .

3. The machine of claim 1 , wherein the second gripping device is composed of a material different than the first gripping device.

4. The machine of claim 1 , wherein the second gripping device is removably secured to at least one side plate of the arm laterally adjacent to the first gripping device.

5. The machine of claim 1 , wherein the second gripping device is interchangeably securable near the first gripping device, the second gripping device having a formed profile along a surface opposite the second gripping feature for permitting mutual conformal contact with the arm and with a side portion of the first gripping device.

6. The machine of claim 1 , wherein the second gripping device including a layer of resilient material removably securable over at least a portion of the second gripping feature.

7. The machine of claim 6 , wherein the layer is secured to the second gripping device along a surface adjacent to the second gripping feature.

8. The machine of claim 6 , wherein the second gripping device is removably secured to one or more opposed side plates of the arm and a bottom plate is positioned between the opposed side plates and in and installed position the second gripping device abuts at least one side plate and the bottom plate.

9. A second gripping device removably securable to a pivotable arm of a work machine having a first gripping device having a first gripping feature formed within at least one sidewall of the arm the arm operatively connected to an attachment such that an object can be secured between the first gripping device and the attachment, the second gripping device removably securable to the arm generally laterally adjacent with the first gripping device, the second gripping device comprising a second gripping feature positioned at least as far outwardly from a base plate of the arm as the first gripping device.

10. The second gripping device of claim 9 , wherein the first gripping device and second gripping device are located near a contact point between the attachment and the arm when the attachment is in a retracted position.

11. The second gripping device of claim 9 ,wherein the first gripping feature is substantially similar to the second gripping feature.

12. The second gripping device of claim 9 , wherein the first gripping feature is different than the second gripping feature.

13. The second gripping device of claim 9 , wherein the second gripping device is composed of a material different than the first gripping device.

14. The second gripping device of claim 9 , wherein the second gripping device is removably secured to one or more opposed side plates of the arm and a bottom plate is positioned between opposed side walls and in an installed position the second gripping device abuts at least one side plate and the bottom plate.

15. The second gripping device of claim 10 , wherein the second gripping device is interchangeably securable near the first gripping device, the second gripping device having a formed profile along a surface opposite the second gripping feature for permitting mutual conformal contact along a pair a corresponding surfaces between the second gripping device and the arm.

16. The second gripping device of claim 15 , wherein the second gripping device including a layer of resilient material removably securable over at least a portion of the second gripping feature.

17. The machine of claim 16 , wherein at least one sidewall of the arm has an attachment feature for removably securing the second gripping device.
