Abstract
Apparatus for attachment to a refuse truck for moving a refuse container platform from a ground loading station to elevated, inverted dumping and/or washing stations above the truck bed includes a pair of elevating assemblies connected to the sides of the truck body and to the container platform that act substantially in unison to move the container platform relative to the truck bed. Each elevating assembly includes an arm assembly connected to the container platform and pivoted by a hydraulic cylinder. Each arm assembly has first and second arms pivotally connected to one another. In operation, the second arm is pivoted relative to the first arm into a vertical position to move the container platform from ground level to a position above the truck bed, then both arms pivot together to move the container platform horizontally forwardly over the truck bed but not substantially higher off the ground. As the latter movement continues, the second arm begins to reversely pivot relative to the first arm so that the arm assembly straightens as it approaches the forward end of the top of the truck bed.
