Abstract: An elongate waste storage container having two top hatches serving as inlets for loading the container. The hatches are sealed by movable hatch lids. A trolley running on a track on the top of the container is arranged to pick up one of the lids at a time and transport it to a position over the other lid for storing during loading of the open hatch. The lifting mechanism on the trolley has a parallogram linkage permitting single operator handling.
