Abstract: A cover deployment system includes a flexible cover configured to span an open top of a trailer, the trailer having a front end, a rear end, and longitudinally extending side walls extending therebetween, bow assemblies connected to the cover, and a cable system including a pair of cables, an electric actuator, a manual actuator, and a differential. The cables extend longitudinally along the longitudinal side of the trailer. Each cable defines a loop supported by a pulley at the front end of the trailer and a pulley at the rear end of the trailer. The remaining bow assemblies are movably attached to the cables. The electric actuator and the manual actuator are operatively connected to a differential positioned between the electric actuator, the manual actuator, and the pulley. The differential is connected and rotates a pulley to move the cables, thereby moving the cover between closed and open positions.

Abstract: A rolling tarp deployment system includes a trailer, a bulkhead fixed to the trailer, first and second bows movable along the trailer, first and second tensioning assemblies, and a cover. The first tensioning assembly has a first member secured to the first bow, a second member secured to the bulkhead, and a first actuator configured to engage the first and second members to restrain the first bow to the bulkhead. The second tensioning assembly has a third member secured to the second bow, a fourth member fixed to the trailer, and a second actuator configured to engage the third and fourth members and move the second bow away from the bulkhead. The cover is tensioned when both the first and second members and the third and fourth members are engaged.

Abstract: A rolling tarp locking system comprising a bow including a cam plate defining a cam profile having a proximal end and a distal end; and a locking assembly including an arm configured to move between a locked position and an unlocked position, the arm having a follower configured to move relative to the cam profile of cam plate from the proximal end and to the distal end such that when the arm moves from the unlocked position to the locked position the bow is pulled toward the locking assembly to a fixed position.

Abstract: A shipping system for a rolling tarp system has a trailer bed and first and second guide tracks attached to the trailer bed. The trailer bed has a towing element that defines front, sides, and rear portions. The first and second guide tracks are transverse to the trailer sides and configured to support the rolling tarp system. The rolling tarp system is loaded on and unloaded off the first and second guide tracks along the side of the trailer bed.

Abstract: A convertible tarp system provides an extendable and retractable enclosure especially suited for covering a flatbed trailer. The convertible tarp system includes a plurality of bows and trolleys that support a tarp structure. A guide track defines a longitudinal path of movement and supports the trolleys for movement along the longitudinal path. The guide track is configured to substantially restrict lateral movement of the trolleys along the longitudinal path.

Abstract: A structural support and hinge member for a trailer tarpaulin latching system includes a mounting face, a support bracket, and a pivot defining a pivot axis.

Abstract: A retractable top covering system has a top covering configured to cover an open top area of a container having sides that define an interior space. The top covering is connected to a retractable top drive mechanism that selectively retracts and deploys the retractable top covering. A track is supported along an upper edge of the container around a portion of the open top area. The track supports at least one trolley for relative movement along the upper edge of the container. A support bow is connected the trolley and supports the retractable top covering. A cable, connected between the retractable top drive mechanism and the trolley, moves the trolley along the track in response to retraction and deployment action of the retractable top drive mechanism.
