A cover system for a transportable container may include a base assembly including a pivot shaft having a pivot axis, and a pivot assembly pivotally coupled to the base assembly for movement about the pivot axis between a first position for stowing the flexible cover and a second position for deploying the flexible cover. The cover system may further include a biasing member coupled to the pivot assembly and a cam pulley system supported on the pivot shaft. A flexible tension element is coupled to the cam pulley system and the biasing member and engaged with the cam pulley. Pivoting movement of the pivot assembly from the first position toward the second position increases engagement between the flexible tension element and the cam surface, and pivoting movement of the pivot assembly from the second position toward the first position decreases engagement between the flexible tension element and the cam surface. The biasing member exerts a tension force on the flexible tension element that urges the flexible tension element out of engagement with the cam surface to pivot the pivot assembly toward the first position and deploy the flexible cover.

An apparatus for extending and retracting a cover over a bed of a vehicle transporting material therein. The apparatus comprises an arm assembly, a motor and a tarp reel for rolling and unrolling a tarp to uncover and cover the vehicle bed. To improve tarp tensioning, rollers are provided on a bracket in which the reel seats when the tarp is unrolled. Locations of sliding friction found in known designs are avoided and replaced with rolling friction. Rolling friction is significantly less than sliding friction and thus greater levels of motor output torque can be incorporated into stretching the tarp tighter before the motor is shut off. At this point of the covering operation, the vehicle bed is covered and the tarp held taut. The bracket may also be configured to provide a braking effect to the reel to assist in holding the tarp in tension.

Self-correcting drive and motor control for cargo canopy systems
In the coupling of bi-directional, non-freewheeling-type DC motors (24,25) to the pulling spool (23) of a canopy (11) deployment strap (21,22) and to a take-up roller (15), ratchet gears (26,27) assure automatic alignment and synchronization of the deployment and retraction mechanisms. The reverse direction rotation of the unwinding motor can be uninhibited through the slipping of its ratchet gear when the winding motor is slow to take up the pulling strap or the tarp (11) being wound thereon. The slipping provides sufficient slack to accommodate changes of spool and roller diameters as more material is successively wound thereon. A friction brake acting against a flange of die spool keeps it from spinning freely when not engaged by the motor. Winding motors can be protected against excessive power use by measuring the level of drawn current with a digital ammeter. If the current exceeds a threshold level of operation, a timer is started. As soon as a given absolute safe period of operation is surpassed, a breaker switch is tripped interrupting the motor power supply. A plural number of trip points can be programmed into the device.

A canopy deployment and retraction mechanism particularly suited to cover the cargo compartment of an elongated vehicle such as a railroad car. Each of a series of tarpaulin-supporting, parallel bows has sliders at each end sliding in a pair of funnel-shaped channels having their flat bases vertically secured to the upper inside lateral wall sections of the compartment. The spacing between the bases of the channels is less than the total length of a bow and its sliders and provides a degree of play in order to accommodate slight variations in the width of said compartment, and allows for self-centering of the cover. The shape of the channels allows for the placement of the cover retraction mechanisms such as cables and sliders within the outer periphery of the container, reducing bulk. The downward slope of the channel lower side further improves the evacuation of debris under the wiping action of the traveling sliders. The upward slope of the channel upper side further improves the sealing of the deployed canopy against the intrusion of rain water.
A roll tarp system with a rear assembly including a pivoting arm and cable to help deploy the roll tarp system. The pivoting arm and flexible cable can articulate to allow a rear door to open. The roll tarp system includes a conventional roll tarp on a roller attached to one side of a container of a truck or trailer and an actuator to operate the tarp. A pivoting arm can be attached to the outside of a rear opening door on the container. A flexible cable has one end attached to the distal end of the pivoting arm and another end attached to the tarp axle of the roller of the roll tarp. Preferably, the flexible cable consists of the only structure between a cable attachment at the pivoting arm and an attachment at the axle of the roller.
A foldable canopy cover (13) can be automatically extended over the open top (11) of a container (12). The canopy is supported by a series of arcuate booms (14) transversally spanning the top of the container. Each boom is secured at opposite ends to a pair of train members riding on rails (16,17) running along the lateral upper edges of the container. At the end of the covering movement, as the leading edge (27) of the canopy approaches the end (32) of the container, it is brought down flush with the container rim by contact between a cam ramp (37) associated with the container and a roller pin (35) on a lever (30) supporting the leading edge of the canopy, in order to tightly close the open top.
An assembly for covering a load on a truck comprises a tower (22), a rotatable axle (66) fixedly mounted with respect to the tower, and a base (40) connected to the axle. The base is rotatable to a position above horizontal by a linkage (70).
