Abstract:
For use with a vehicle of a type having a body mounted with a chassis, the body having an opening for receiving refuse therethrough, a packer and ejection assembly for moving and storing refuse in the body through the opening and ultimately ejecting the refuse from the body, the packer and ejection assembly comprising:a platen mounted with the body to urge refuse into the body through the opening and ultimately eject the refuse from the body;a linkage assembly including a linkage element having a first end and a second end and an extendible element having a first end and a second end, the first end of the linkage element being pivotally attached to the body, the second end of the linkage element being pivotally coupled to the first end of the extendable element, and the second end of the extendible element being pivotally attached to the platen; anda hydraulic drive assembly pivotally attached to the body and to the linkage element intermediate the first end and the second end thereof for movement in reciprocal directions upon actuation of the hydraulic drive assembly such that during movement of the platen through a rearward stroke the speed of the platen decreases and the force exerted by the platen on the refuse increases throughout the rearward stroke and during movement of the platen through a forward stroke the speed of the platen increases, the linkage assembly being movable in reciprocal directions for moving the platen in reciprocal directions.
