Abstract

A grabber assembly includes a carriage, an adapter assembly, and a grabber arm. The adapter assembly is coupled to the carriage and includes a pin, a first member, a second member, and a sleeve. The first member is configured to receive a first end of the pin and removably fixedly couple with the first end of the pin. The second member is configured to receive a second end of the pin and removably fixedly couple with the second end of the pin. The sleeve extends co-cylindrically with the pin. The grabber arm includes a bushing. The bushing is fixedly coupled with the grabber arm and is pivotally coupled to the pin. The sleeve is positioned within a central bore of the bushing, between the bushing and the pin.

First claim

What is claimed is:

1. A grabber assembly comprising:
a carriage;
an adapter assembly coupled to the carriage, the adapter assembly comprising:
a pin;
a first member configured to receive a first end of the pin and removably fixedly couple with the first end of the pin;
a second member configured to receive a second end of the pin and removably fixedly couple with the second end of the pin;
a sleeve extending co-cylindrically with the pin; and

a grabber arm comprising:
a bushing fixedly coupled with the grabber arm, wherein the bushing is pivotally coupled to the pin;

wherein the sleeve is positioned within a central bore of the bushing, between the bushing and the pin.

2. The grabber assembly of claim 1 , wherein the sleeve is manufactured from or include a polymeric material.

3. The grabber assembly of claim 1 , wherein the first end of the pin is removably coupled with the first member with a first coupler and the second end of the pin is removably coupled with the second member with a second coupler.

4. The grabber assembly of claim 1 , wherein the first member is fixedly coupled with a first attachment member and the second member is fixedly coupled with a second attachment member, wherein the first attachment member and the second attachment member are planar members configured to removably couple with a corresponding portion of the carriage.

5. The grabber assembly of claim 1 , further comprising another of the adapter assembly and another of the grabber arm, wherein the adapter assembly and the grabber arm are positioned at a first end of the carriage and the other adapter assembly and the other grabber arm are positioned at a second end of the carriage.

6. The grabber assembly of claim 1 , wherein the bushing, the pin, the first member, the second member, and the sleeve are co-axial.

7. The grabber assembly of claim 1 , wherein at least one of:
the grabber arm and the bushing are configured to rotate or pivot relative to the sleeve and the pin; or
the grabber arm, the bushing, and the sleeve are configured to rotate or pivot relative to the pin.

8. A grabber assembly comprising:
a carriage;
an adapter assembly coupled to the carriage, the adapter assembly comprising:
a sleeve;
a pin extending through the sleeve, the pin comprising a longitudinal passageway and one or more radially extending passageways that fluidly couple with the longitudinal passageway and a gap defined between a radially inwards facing surface of the sleeve and a radially outwards facing surface of the pin;
a first member configured to receive a first end of the pin and pivotally couple with the first end of the pin;
a second member configured to receive a second end of the pin and pivotally couple with the second end of the pin; and

a grabber arm comprising:
a bushing fixedly coupled with the grabber arm, wherein the bushing is configured to pivotally couple with the pin.

9. The grabber assembly of claim 8 , wherein the first end and the second end of the pin each include a step, wherein the step is defined between a central portion of the pin and end portions of the pin.

10. The grabber assembly of claim 9 , wherein the step of the first end and the second end of the pin is configured to engage or abut a correspondingly shaped step of the first member or the second member.

11. The grabber assembly of claim 8 , wherein the radially outwards facing surface of the pin slidably couples with the radially inwards facing surface of the sleeve.

12. The grabber assembly of claim 8 , wherein the pin comprises a grease fitting fluidly coupled with the longitudinal passageway at an inlet of the longitudinal passageway.

13. The grabber assembly of claim 8 , wherein the first end of the pin is received within a stepped inner volume of the first member and the second end of the pin is received within a stepped inner volume of the second member.

14. The grabber assembly of claim 8 , wherein the first member is fixedly coupled with a first attachment member, and the second member is fixedly coupled with a second attachment member, wherein the first attachment member and the second attachment member are planar members configured to removably and fixedly couple with the carriage.

15. A grabber assembly comprising:
a carriage;
a grabber arm pivotally coupled with the carriage;
a double-action cylinder configured to extend and retract to pivot the grabber arm relative to the carriage, wherein the double-action cylinder is configured to pivotally couple with the grabber arm at a first end of the double-action cylinder and pivotally couple with the carriage at a second end of the double-action cylinder through a mount assembly, the mount assembly comprising:
a first mounting member and a second mounting member fixedly and removably coupled with the carriage;
a cylindrical member extending between the first mounting member and the second mounting member, wherein the cylindrical member extends through a corresponding aperture of the second end of the double-action cylinder;
a first bushing positioned within a bore of the first mounting member; and
a second bushing positioned within a bore of the second mounting member;
wherein the cylindrical member extends through a central aperture of the first bushing and the second bushing;
wherein the cylindrical member is fixedly coupled with at least one of the first mounting member and the second mounting member through a connection member.

16. The grabber assembly of claim 15 , wherein the first mounting member and the second mounting member are fixedly and removably coupled with portions of the carriage that are substantially perpendicular to each other.

17. The grabber assembly of claim 15 , wherein the connection member is an elongated member comprising:
a first end; and
a second end comprising a protrusion;
wherein the first end of the connection member is fixedly coupled with the second attachment member and the protrusion of the second end is configured to interlock with a correspondingly shaped recess formed in an end of the cylindrical member.

18. The grabber assembly of claim 15 , wherein the mount assembly further comprises an outer bushing, wherein the first bushing is positioned within the outer bushing and the outer bushing extends through an aperture of the carriage and an aperture of the first mounting member.

19. The grabber assembly of claim 18 , wherein the outer bushing, the first bushing, and the cylindrical member are co-cylindrical with each other.

20. The grabber assembly of claim 15 , wherein the double-action cylinder further comprises a lubricant fitting, wherein the lubricant fitting is configured to fluidly couple with a space defined between a radially inwards facing surface of the second end of the double-action cylinder and a radially outwards facing surface of the cylindrical member.
