Abstract

A grabber assembly has a beam assembly with a bracket. A grabber gear assembly is coupled with the bracket. The grabber gear assembly has a pair of gear mechanisms coupled with the bracket. Each gear mechanism has a shaft and a pair of thrust bearings, one at each end of the shaft. A grabber arm mounting pad is coupled with each shaft. A gear section is coupled with each shaft. The gear sections of each shaft mesh with one another to drive the grabber arm mounting pads. An actuating driver is coupled with one of the shafts to drive the grabber gear assembly and move the arms between an open and grasping position.

Claims

1. A grabber assembly comprising:

a beam assembly;

a bracket on the beam assembly;

a grabber gear assembly coupled with the bracket;

the grabber gear assembly comprising a pair of gear mechanisms coupled with the bracket, each gear mechanism including a pair of thrust bearings and a shaft with two ends, the shaft includes one of the pair of thrust bearings at each of its two ends;

a grabber arm mounting pad coupled with the shaft;

a gear section is coupled with each shaft, the gear sections of each shaft mesh with each other to drive the grabber arm mounting pads; and

an actuating driver is coupled with one of the shafts to drive the grabber gear assembly.

2. The grabber assembly of claim 1, wherein one of the pair of thrust bearings is secured with the bracket on the beam.

3. The grabber assembly of claim 1, further comprising a pair of grabber arms, each grabber arm coupled with one of the grabber arm mounting pads.

4. The grabber assembly of claim 3, wherein the pair of grabber arms are manufactured from spring steel.

5. The grabber assembly of claim 1, wherein the actuating driver is a cushioned cylinder.

6. The grabber assembly of claim 1, wherein a bracket extends from one of the shafts to couple with the actuating driver.

7. The grabber assembly of claim 1, wherein the mounting pad includes a bracket to secure with the shaft and the gear section is coupled with the mounting pad bracket.

8. The grabber assembly of claim 1, wherein the thrust bearings are spherical thrust bearings.

9. A refuse container and grabber arm comprising:

a container for receiving refuse;

a grabber arm for dumping a refuse cart into the container, the grabber arm comprising;

a beam assembly coupled with the container;

a bracket on the beam assembly;

a grabber gear assembly coupled with the bracket;

the grabber gear assembly comprising a pair of gear mechanisms coupled with the bracket, each gear mechanism including a pair of thrust bearings and a shaft having two ends, the shaft includes one of the pair of thrust bearings at each of its ends;
