Abstract: An apparatus for opening and closing a cover of a truck is disclosed. The apparatus includes a rotatable shaft that can be connected to multiple support anchors in order to provide a torsion force to each of the supports to pivotably rotate the supports and the cover between an opened position and a closed position. The support anchors are attachable to the cover and are pivotably attached at an end of each support to the rotatable shaft. A plurality of offset hinges pivotably attaches the shaft to the container and rotatably receives the shaft. An actuator is used to provide rotary motion to the shaft. The actuator includes hydraulic cylinders and a chain and sprocket for converting linear motion of the cylinder to rotary motion of the shaft.

Abstract: An apparatus for opening and closing a cover of a truck is disclosed. The apparatus includes a rotatable shaft that can be connected to multiple supports in order to provide a torsion force to each of the supports to pivotably rotate the supports and the cover between an opened position and a closed position. The shaft is hexagonal in cross-section. The supports are attachable to the cover and are pivotably attached at an end of each support to a side of the container, for supporting the cover and moving the cover between an open position and a closed position. A plurality of hinges are used to pivotably attach the supports to the container and to rotatably receive the shaft proximate to and parallel to the one side of the container. An actuator is used to provide rotary motion to the shaft. The actuator includes a hydraulic cylinder and a chain and sprockets for converting linear motion of the cylinder to rotary motion of the shaft.

Abstract: An apparatus mounts a covering system of a truck. The apparatus can have a stud, a lock ring, a retaining plate, and means for releasably attaching the apparatus to the truck. The stud can have a base and a shaft having an anchor for receiving a reaction end of an at least one spring. The lock ring can have a pocket having a complementary shape to the base of the shaft for adjustably rotating the stud through a three-hundred sixty degree (360°) range. The retaining plate can have an aperture for receiving the shaft. The means for releasably attaching the apparatus can include at least one fastener.

Abstract: A truck cover having an improved telescopic arm assembly for drawing a cover across an open topped truck body or other vessel or container. The assembly is powered by a pneumatic, hydraulic or other power source and comprises a pair of pivoting telescopic arms motivated by actuators The activators cause the telescopic arms to move pivotally from one end of the container to the opposite end and during the pivotal movement to cause the telescopic arms to retract as they move to a vertical position and to extend as they move from the vertical position to the opposite end of the container. The extension and retraction of the telescopic arms during pivotal movement from one end of the container to the opposite end causes a flexible cover carried by the upper ends of the telescopic arms to be drawn across the container in a low trajectory resulting in improved ease and safety of operation and reduced opportunity for damage to the flexible cover.
