Abstract: A retainer assembly for a waste container opening defining a longitudinal axis passing through a center of the opening includes a framework defining a first framework opening, and a pivotable finger assembly including a retainer portion, the retainer portion pivotably adjacent the first framework opening. The finger assembly includes a biasing element for urging the retainer portion toward the longitudinal axis. The retainer portion is movable against the biasing element away from the longitudinal axis to enable placement of waste materials into the waste container, and movable toward the longitudinal axis after waste materials have been placed into the waste container to impede movement of waste materials through the first framework opening out of the waste container.

Abstract: An apparatus includes an elevated structure extending along and above a receptacle, a trolley for travel along the elevated structure, a trolley bucket supported by the trolley for receiving and discharging unconsolidated material, and a high-lift structure including a rotatable dumper lift for lifting unconsolidated material from a first elevation to a second elevation greater than the first elevation, and discharging unconsolidated material into the trolley bucket. The high-lift structure is operably coupled with the elevated structure. The rotatable dumper lift can receive a first volume of unconsolidated material at the first elevation, lift the first volume from the first elevation to the second elevation, and discharge the first volume into the trolley bucket. The trolley bucket can discharge the first volume of unconsolidated material into the receptacle while the rotatable dumper lift receives a second volume of unconsolidated material at the first elevation.
