Cart that retrieves, transports, lifts and empties waste container

A cart adapted to retrieve a portable waste container from a compactor, to transport the portable waste container to a larger waste receptacle, and to lift and rotate the waste container to empty the contents of said waster container into said waste receptacle, comprising:

• a vertical frame including a pair of parallel, transversely opposed channel members;
• a base frame positioned between and adapted to movably engage said channel members;
• said base frame being movable between an upper end of said vertical frame and a lower end of said vertical frame;
• a waste container-engaging frame secured to said base frame;
• said waste container-engaging frame including a back frame secured to said base frame and a pair of parallel container-engaging arms secured to opposite ends of said back frame, said parallel container-engaging arms disposed in a horizontal plane normal to said back frame;
• winch means for selectively lifting and lowering said base frame along the vertical extent of said vertical frame;
• a barrier means fixedly secured to a preselected one of said channel members of said vertical frame;
• a waste container rotating means secured to said back frame;
• a track formed in said waste container rotating means, said track having a vertical part, a horizontal part, and a gradual ninety degree bend in open communication with said vertical and horizontal parts;
• said track being in vertical alignment with said barrier means so that said barrier means enters into said track when said winch means lifts said base frame to a first preselected elevation above said barrier means;
• said waste container being gradually rotated as said barrier means encounters said gradual ninety degree bend as said winch means lifts said base frame to a second preselected elevation above said first preselected elevation;
• and
• said waste container-engaging means adapted to hold said waste container as said waste container is rotated so that contents of said waste container fall from said waste container under the influence of gravity when said waste container is rotated.
