Abstract

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

Claims

1. A telescopic side arm for a refuse vehicle, comprising:

an outer boom defining a bore;

an inner boom received in the bore of the outer boom;

a mounting assembly on the outer boom for securing the outer boom with the refuse vehicle;

a plurality of bearing pads between the inner boom and the outer boom, the plurality of bearing pads in contact with an inner surface of the outer boom defining the bore;

a plurality of shims associated with the bearing pads for assuring a tight fit between the inner boom and the outer boom, each shim includes a body having a pair of legs connected by a web and an attachment mechanism for enabling securement of the shim to the outer boom or inner boom.

2. The telescopic arm according to claim 1, wherein the outer boom in cross-section has a polygonal configuration with an overall U-shaped portion with legs at an obtuse angle with respect to a web.

3. The telescopic arm according to claim 2, wherein the inner boom in cross-section has a polygonal configuration with an overall U-shaped portion with legs at an obtuse angle with respect to a web.

4. The telescopic arm according to claim 1, wherein the mounting assembly further comprises:

a pin inserting into a bracket on the refuse vehicle;

a plate coupled with the pin to maintain the pin in the bracket;

a bearing sliding over the pin to provide a bearing surface and enable quick change of the mounting assembly; and

a mechanism coupling with the outer boom.

5. The telescopic arm according to claim 1, further comprising a bearing pad bracket having an overall U-shaped with legs at an obtuse angle with respect to a web, the legs and web including an aperture to receive the plurality of bearing pads, and a tongue extending into the apertures to retain the pads on the bracket.

6. The telescopic arm according to claim 1, wherein each shim includes a tab extending from the web, the tab being substantially perpendicular to the web.

7. A telescopic side arm for a refuse vehicle, comprising:

an outer boom defining a bore;

an inner boom received in the bore of the outer boom;

a mounting assembly on the outer boom for securing the outer boom with the refuse vehicle, the mounting assembly further comprising;

a pin inserting into a bracket on the refuse vehicle;

a plate coupled with the pin to maintain the pin in the bracket;

a bearing sliding over the pin to provide a bearing surface and enable quick change of the mounting assembly;

a mechanism coupling with the outer boom;

a plurality of bearing pads between the inner boom and the outer boom, the plurality of bearing pads in contact with an inner surface of the outer boom defining the bore; and

a plurality of shims associated with the bearing pads for assuring a tight fit between the inner boom and the outer boom.

8. A telescopic side arm for a refuse vehicle, comprising:

an outer boom defining a bore;

an inner boom received in the bore of the outer boom;

a mounting assembly on the outer boom for securing the outer boom with the refuse vehicle;

a plurality of bearing pads between the inner boom and the outer boom, the plurality of bearing pads in contact with an inner surface of the outer boom defining the bore;

a bearing pad bracket having an overall U-shaped with legs and a web, the legs and web including an aperture to receive the plurality of bearing pads, and a tongue extending into the apertures to retain the pads on the bracket; and

a plurality of shims associated with the bearing pads for assuring a tight fit between the inner boom and the outer boom.
