  • Publication number: 20230392429
    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.

  • Patent number: 11701951
    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.
