Abstract
Abstract A refuse container assembly for storing refuse material at a refuse transfer station is provided with a receptacle, having a refuse storage chamber and a refuse material intake and discharge opening at the upper end of the chamber, mounted on a support frame for pivotal movement about a pivot axis extending transversely of the receptacle between a lower, upright position for receiving and storing thereat refuse material discharged into the opening by refuse collection vehicles and an elevated, at least partially inverted, position for discharging refuse material from the container through the opening into a refuse transportation vehicle, the assembly including a mechanism for pivoting the receptacle between the lower and elevated position, the mechanism including arms mounted on the support frame for pivotal movement about a pivot axis extending transversely of the receptacle, first extendable and retractable actuator having one end connected to the support frame and the other end connected to the arms remote from the pivot axis and second extendable and retractable actuator having one end connected to the receptacle and the other end connected to the arms remote from the pivot axis of the arms, each actuator being retracted in the lower position of the receptacle and being operable, when extended, to pivot the receptacle a portion of the angular displacement between the lower and elevated positions.
