Abstract: A cover system for an open-topped container, such as a dump truck body, includes a flexible tarpaulin sized to extend across the length of the container. A weighted element is carried by the tarp adjacent to but offset from the front end of the tarp. The weighted element is “gravity-biased” so that it pulls the tarp down and holds it down against the load within the container when the tarp is in its deployed position. In a preferred embodiment, the weighted element includes one or more metal bars that are contained within pockets spanning the width of the tarp.

Abstract: An automatic tarp tensioning device operable to remove slack from a tarp cover due to stretching and wear includes an extension mechanism attached to a tarp cover and an adjusting element attached to the tarp cover and movable relative to the extension mechanism to apply tension to the tarp cover. A biasing mechanism is disposed between the extension mechanism and the adjusting element to bias the adjusting element away from the extension mechanism to thereby tension the tarp cover. The biasing mechanism includes a plurality of springs under compression between the extension mechanism and the adjusting element and a limiting element to limit the maximum extension of the spring. The limiting element includes a bolt and nut assembly interconnecting the extension mechanism and the adjusting member and is adjustable to control the expansion of the spring. The device operates to automatically tension the tarp cover when the cover is deployed.

Abstract: An endless cable tarp extension/retraction system spooled around front and rear pulleys includes drive components that are self-contained and encapsulated within an elongated housing that can be removably mounted to the container body using multiple clamp assemblies or mounting bolts disposed within a T-slot in the housing. A front idler pulley is provided that is sized and oriented relative to the drive pulley to maintain the upper and lower runs of the cable to travel essentially parallel along the length of the container. A self-tensioning rear idler pulley is provided that utilizes a spring to exert an adjustable force against the rear idler pulley. In another aspect of the invention, an anti-sail bracket extends downward from the bow ends of the tarp system and includes an inwardly projecting pin that is restrained from upward movement by a rail mounted to the side of the container.

Abstract: An improved tarp cover system for covering the open-topped container body of a vehicle is characterized by the provision of generally U-shaped inverted hold-down arm that is pivotally connected with the front wall of the container body and that is spring biased to apply a downward force on the front portion of the cover when the container is in the completely closed condition, thereby to reduce flapping of the cover during transport. The flexible tarp cover is wound on a roll that is rotatably supported adjacent the front wall of the container. In a first embodiment, to cover the container, the free end of the cover is displaced rearwardly of the container by a cover arm that is pivotally connected with the side walls of the container. The cover arm is biased toward its rearmost container covering position by a pair of side mounted spring arrangements that include compression springs that are concealed within the hollow leg portions of the cover arm.

Abstract: A cover system for an open top container, such as a dump truck bed, includes a pair of pivoting load arm assemblies, one mounted on each side of the bed, configured to jointly convey a cover tarpaulin over a heaped load within the bed. In one embodiment, the load arm assembly includes a pair of telescoping arms, with a lower arm pivotably mounted to an upper rail of the dump bed. The free end of the upper arm of each assembly includes a yoke, formed by a pair of arms diverging to form a notch. The notch is configured to catch or receive a pull bar connected to a retractable tarp. The notch opening is maintained at the level of the edge of the dump bed side boards by a catch projecting generally perpendicular to the yoke. The retractable tarp is unwound from a roller at one end of the dump bed, preferably using a pull rope attached to the pull bar. As the tarp is initially unfurled, the pull bar rides on the side boards of the dump bed until it reaches the position of the load arm yokes.
