Telescopic arm for a refuse vehicle
View Patent ↗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.
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.
