Abstract: The invention comprises a modular lifter for a tarpaulin system, comprising: a) a plurality of tubes, each end of each tube being a hollow end, and the tubes operative to be assemblable into a lifter for a tarpaulin system; b) a plurality of hinges, each hinge having a body, opposed tube mounting ends extending longitudinally from the body and dimensioned to fit within the hollow ends of the tubes, and locking mount extending from the body substantially perpendicular to the mounting ends; and c) a locking mechanism, operative to couple two of said hinges together via respective locking mounts.

Abstract: The invention comprises a tensioning assembly for a tarpaulin, comprising: a) a track for mounting a bow for supporting the tarpaulin, the track enabling longitudinal movement of the bow along the track; b) a universal support coupled to bow and operative to support a rod, the rod being oriented substantially parallel to the track; c) a stop element, the stop element moveable from a position over the track to a position removed from said track, and said stop element operative to engage the rod when positioned over the track; and d) a tensioning adjustment mechanism, as part of one of the universal support, the rod and the stop element, the tensioning adjustment mechanism operative to adjust the position of the rod relative to the universal support and thereby maintain the tarpaulin under tension when the rod is engaged to the stop element, wherein said tensioning assembly is operative to maintain the bow substantially parallel to the track while under tension.

Abstract: A cover system for a trailer of a freight transport vehicle having a cargo space, the cover system having a pair of track brackets, tracks, generally U-shaped bow portions mounted to the trucks so that there is displacement of the bow portions as each member of the pair of trucks is displaced along the length of the members of the track and a flexible canopy supported by the bow members for covering or uncovering the cargo space.
