ABSTRACT:
A tarping apparatus for the open top container of a refuse handling truck has a pair of tarp deployment arms on opposite sides of the container that pull the tarp onto and off of the open top of the container as the arms are hydraulically swung back and forth along the container. One end of the tarp is anchored to a stationary mast at the front end of the truck body while the opposite end of the tarp is wound around a spring-loaded take-up roll that pays out the tarp as the arms are swung rearwardly and then automatically rolls up the slack as the arms are returned toward the front end of the truck. If necessary to accommodate dimensional variances between different size containers which may be carried by the truck, the pivot points for the deployment arms may be adjustably shifted by hydraulic cylinders either forwardly or rearwardly such that the arc of travel of the tarp roll is correspondingly displaced either forwardly or rearwardly. The slide cylinders for adjusting the pivot points are connected in a master-slave series relationship to promote uniform operation, and the swing cylinders for the deployment arms are likewise connected in a master-slave series relationship to similarly promote uniformity of operation.
