Cover system for a side-dump container

摘要

A deployment apparatus for a flexible cover sized to cover a side-dump container comprises first and second swing arm assemblies pivotally mounted at a pivot point to opposite sides of the container. A drive assembly connected to the roll tube of the flexible cover is operable to rotate the roll tube so that the flexible cover winds around the roll tube. The drive assembly is slidably supported on one of the swing arms so that the mechanism translates along the length of the swing arm as it winds the flexible cover around the roll tube. A stop is provided on the swing arm between the pivot point and the free end to limit the translation of the drive assembly along swing arm. In another form, the drive assembly is fixed to a swing arm that is slidably received in a pivoting spring mechanism.
