Abstract: A refuse collection vehicle is provided with a dual chute system for receiving sorted refuse from curbside containers that have one or two compartments. A powered lifting system elevates the curbside container, dumping sorted refuse into the dual chute system. A divided diverter plate with two panel portions present within the vehicle chute allows an operator to direct refuse into selected, segregated storage compartments within the refuse vehicle. In this manner, presorted refuse from the curbside container may be collected without any intermingling of such presorted refuse. The diverter plate has one driven portion and one free swinging portion. These portions may be joined by a temporary link to allow the free swinging panel portion to be positioned by the driven panel portion.

Abstract: A self-adapting refuse receptacle lift has a carriage for raising and dumping the contents of a refuse receptacle into a collection load box or refuse gathering vehicle. The carriage is carried on extending arms, the rotation of which may be controlled with a hydraulic or other powered drive device. The carriage includes attachments comprising a pair of moveable clamp arms. The clamp arms have self-adapting features so that a variety of receptacles of different sizes and shapes may be lifted by the apparatus. Sequencing elements rotate the clamp arms down from a vertical stored position into a horizontal position for clamping a receptacle to be dumped. Then, the entire carriage is raised for inverting and dumping and the contents of the receptacle, and then reverse operations follow, whereby the clamp arms return to an upright stored vertical position to be out of the way during the movement of a refuse collecting vehicle.
