Abstract
A trash collecting apparatus is described for mounting on a trash collection vehicle for one man side loading operation. A pair of spaced apart parallel guide rails each having a long vertical straight section and a short curved section at the top are pivotally attached to the vehicle at the top. A power cylinder is provided at the lower end of the guide rails for pushing and retracting the lower end of the guide rails form the vehicle. A pair of grabber arms are provided for grabbing the periphery of the trash can to be emptied. The grabber arms are connected to lifting arms. The lifting arms comprise an upper lifting arm segment and a lower lifting arm segment. A power cylinder drives the lifting arms so that the lower end of the lower lifting arm follows the guide rails to the curved section. The grabber arms and the grabbed container are moved by the lower end of the lower lifting arms and as the lower end of the lifting arms follows the curved portion of the guide, the containers are turned upside down over the opening in the top of the refuse collecting truck. Reverse movement of the lifting arms lowers the trash container.
