Abstract

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

First claim

What is claimed is:

1. A grabber assembly for a refuse vehicle comprising:
a carriage;
a pin extending through a bushing of a first grabber arm, the bushing pivotally coupled with the pin;
a first adapter coupled with the carriage and coupled with a first end of the pin;
a second adapter coupled with the carriage and coupled with a second end of the pin; and
a sleeve positioned within a central bore of the bushing between the bushing and the pin;
wherein the first grabber arm and a second grabber arm are configured to cooperatively pivot to releasably grasp a refuse container;
wherein the pin comprises:
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, the longitudinal passageway and the one or more radially extending passageways configured to receive a lubricant through at least one of the first end or the second end of the pin and provide the lubricant to the gap.

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 fixedly coupled with the first adapter and the second end of the pin is removably fixedly coupled with the second adapter.

4. The grabber assembly of claim 1 , wherein the first end of the pin is integrally formed with the first adapter and rotatably coupled with the second adapter.

5. The grabber assembly of claim 1 , wherein the first adapter is removably fixedly coupled with the carriage, and the second adapter is removably fixedly coupled with the carriage.

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

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

8. The grabber assembly of claim 1 , wherein the pin further comprises a fitting positioned on an exterior surface of the pin, the fitting configured to receive the lubricant from an exterior of the pin and fluidly couple with the longitudinal passageway to provide the lubricant through the longitudinal passageway and the one or more radially extending passageways to the gap.

9. The grabber assembly of claim 1 , 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 first end of the pin is received within a stepped inner volume of the first adapter and the second end of the pin is received within a stepped inner volume of the second adapter.

11. A grabber assembly for a refuse vehicle comprising:
a carriage;
a pin fixedly coupled with a first grabber arm;
an adapter coupled with the carriage and configured to receive an end of the pin to pivotally couple with the pin;
a sleeve positioned within an aperture of the adapter between the adapter and the end of the pin, an inner surface of the sleeve slidably coupled with an outer surface of the pin; and
wherein the first grabber arm and a second grabber arm are configured to cooperatively pivot to releasably grasp a refuse container.

12. The grabber assembly of claim 11 , wherein the adapter is a first adapter, the end of the pin is a first end of a pin, and the sleeve is a first sleeve, the grabber assembly further comprising a second adapter configured to receive a second end of the pin to pivotally couple with the pin, and a second sleeve positioned within an aperture of the second adapter between the second adapter and the second end of the pin.

13. The grabber assembly of claim 11 , wherein the end of the pin includes a step, wherein the step is defined between a central portion of the pin and an end portion of the pin.

14. The grabber assembly of claim 13 , wherein the end portion of the pin is smaller than the central portion of the pin, wherein the end portion of the pin is received within the sleeve and the adapter.

15. The grabber assembly of claim 13 , wherein the outer surface of the pin is a radially outwards facing surface, the radially outwards facing surface of the pin at the end portion of the pin slidably coupled with the inner surface of the sleeve, wherein the inner surface of the sleeve is a radially inwards facing surface.

16. The grabber assembly of claim 11 , wherein the end of the pin is received within a stepped inner volume of the adapter.

17. The grabber assembly of claim 11 , wherein the sleeve is a greaseless sleeve and the inner surface is configured to directly contact the outer surface of the pin.

18. A grabber assembly for a refuse vehicle comprising:
a carriage;
an adapter assembly configured to pivotally couple a first grabber arm with the carriage, the adapter assembly comprising an adapter removably coupled with the carriage, and a pin extending into the adapter, the pin pivotally coupling the first grabber arm with the carriage the adapter assembly comprising a sleeve positioned around the pin, the sleeve configured to contact an outer surface of the pin, wherein the pin is free to rotate relative to the sleeve; and
a double-action cylinder configured to extend and retract to pivot the first grabber arm relative to the carriage;
wherein the first grabber arm and a second grabber arm are configured to cooperatively pivot to releasably grasp a refuse container.

19. The grabber assembly of claim 18 , wherein the double-action cylinder is configured to pivotally couple with the first 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, wherein the mount assembly comprises:
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 a 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.

20. The grabber assembly of claim 18 , wherein the sleeve is positioned within a central aperture of a bushing of the first grabber arm between the bushing and the pin.
