Abstract: A track and roller system for guiding and supporting a sliding tarpaulin for covering a flat-bed trailer and for supporting at least one light means. The track and roller system comprises a track for supporting for a plurality of rollers and a mounting bar. The rollers are connected to base portions of sliding supports for the tarpaulin. The track has at least one interlocking element. The mounting bar supports the at least one light means below the track. The mounting bar has an outwardly facing supporting portion for supporting the at least one light means and an interlocking portion connected to the supporting portion. The interlocking portion has at least one interlocking element for interlocking with the at least one interlocking element of the track.

Abstract: The invention relates to a side lifting/closing tarpaulin system for a flatbed trailer, the trailer having an elongated platform having front and rear ends, sides, a pair of bulkheads of similar construction extending upwardly from the platform at its front and rear ends, and a plurality of tarpaulin supporting beams extending laterally across the platform, and longitudinally along the platform. The system comprises a pair of pivoting arms, each arm supported by a corresponding bulkhead. The arms are pivotable, in corresponding fashion, with respect to a side of the platform, between an upper, open orientation and a lower, closed orientation. Each arm is provided with an elongated slot along a longitudinal axis of the arm. Each arm is mounted relative to the bulkhead such that the pivot sits within the slot in a manner that permits longitudinal movement of the arm relative to the pivot.
