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 configured to receive a first end of the pin;
a second adapter coupled with the carriage and configured to receive a second end of the pin; and
a sleeve extending co-cylindrically with the pin, the 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.

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 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.

9. The grabber assembly of claim 8 , 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.

10. 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.

11. The grabber assembly of claim 10 , 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.

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

13. The grabber assembly of claim 12 , 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.

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

15. The grabber assembly of claim 13 , wherein a radially outwards facing surface of the end portions of the pin slidably couples with a radially inwards facing surface of the first sleeve and the second sleeve.

16. The grabber assembly of claim 12 , 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.

17. 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 a first adapter and a second adapter, each removably coupled with the carriage, wherein a pin extends between the first adapter and the second adapter, the pin pivotally coupling the grabber arm with the carriage; and
a double-action cylinder configured to extend and retract to pivot the first grabber arm relative to the carriage, 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 first grabber arm and a second grabber arm are configured to cooperatively pivot to releasably grasp a refuse container.

18. The grabber assembly of claim 17 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 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.

19. The grabber assembly of claim 17 , wherein the adapter assembly further comprises a sleeve extending co-cylindrically with the pin, the sleeve positioned within a central aperture of a bushing of the first grabber arm between the bushing and the pin.

20. The grabber assembly of claim 17 , wherein the adapter assembly further comprises:
a first sleeve positioned within an aperture of the first adapter between the first adapter and a first end of the pin; and
a second sleeve positioned within an aperture of the second adapter between the second adapter and a second end of the pin;
wherein the pin comprises a first step and a second step, the first step and second step defining the first end of the pin, the second end of the pin, and a central portion of the pin.
