Abstract
Abstract This invention relates to a garbage and refuse vehicle which has a continuous compacting system, which compacting system is supplied with garbage or refuse by a semi-automated pick-up device which picks up the container, unloads the contents thereof into a hopper of the compacting system, and moves the refuse container back to the same position it originally occupied, without manual manupulation of the refuse container while it is being picked up, unloaded and positioned on a rack, on the terrain, or the like. Provision is made for handling either round or polygonal containers, the handling of which container may be controlled, by one operator, from the cab of the vehicle. The device may be made as an attachment to a existing garbage or refuse vehicle, or it may be made of unitary construction therewith. The container may be dumped by cam action, or by action of a motor.
