Abstract: A tarp for a vehicle bed is developed for engagement with a reel that is rotated by a motor for rolling and unrolling the tarp across a vehicle bed. When the tarp has been unrolled and fully covers the vehicle bed, the tarp stretches across the vehicle bed and has side edges supported upon the respective upper edges of the bed side walls. The features or structures of the tarp that are kinematic are designed such that they may be permanently attached to the other members in the machine or tarp system, which thereby meets functional needs of the tarp, and provide long term consistent deployment of the tarp covering sections. The material used in this kinematic part of the tarp is chosen such that the life of this component is improved. Additionally, covering sections are provided in this tarp configuration.

Abstract: 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.

Abstract: A roll tarp system for a truck or trailer having a container with a rear door. The roll tarp system includes a roll tarp mounted to an axle assembly and a cable coupler assembly coupled to the axle assembly. A flexible cable connects the cable coupler assembly to a rear arm which is pivotally attached to the rear door. The cable coupler assembly includes first and second hinge members and is rotatably coupled to the axle assembly to permit unrolling and rolling up of the tarp and to permit opening of the rear door in a sideways or upward direction. The cable coupler assembly may include one or more apertures to permit access to a manual drive shaft which passes through the cable coupler assembly.

Abstract: A roller tarp system for covering a truck bed includes a first pivot arm assembly pivotally coupled to one side of the truck bed and a second pivot arm assembly pivotally coupled to an opposite side of the truck bed. A generally hollow and cylindrical tarp spool extends along a longitudinal axis between opposite first and second ends. The tarp spool is rotatably coupled between the first and second pivot arm assemblies for rotatably supporting a flexible tarp cover. A drive assembly is housed within the tarp spool adjacent one of the first and second ends. The drive assembly is operatively coupled between one of the first and second pivot arm assemblies and the tarp spool for selectively rotating the tarp spool and actuating the tarp system between an open position uncovering the truck bed and a closed position covering the truck bed.

Abstract: A one-touch controller for a tarp system with varying phases or modes based on a single touch to operate. The one-touch controller module controls a motor of a tarp, such as a geared brake motor, and a switch or a remote control system with a button to push to operate a vehicle tarp system with one touch of the button. The one-touch controller preferably has solid state circuitry that controls power to and direction of the motor and detects amp variations from the motor to automatically shut off the system. The remote control system preferably operates in various modes based on how long the button of the remote control is touched, such as with short touches of the button being incremental operation, other touches permitting the entire cycle in automatic operation, and touches longer than a set time being “press and hold” operation.

Abstract: A hydraulic brake gear motor with a brake mechanism to operate a roll tarp for use with an open top container. A motor-driven rollable cover is attached to and wrappable about a reel to selectively cover contents of the container. The hydraulic gear motor operates with a brake mechanism to lock and hold a position of the motor. A secondary brake mechanism may include a hydraulic piston that selectively engages a holding brake with a hex connector. A hydraulic motor may include a port path for flow of fluid to internal meshing gears and a braking mechanism with a plunger that clamps and holds the meshing gears when hydraulic fluid is not flowing. A transmission having rolling gears can be operated by the hydraulic motor with such brake mechanisms. The motor and brake mechanisms are preferably hydraulically operated with an existing system of a trailer or rail car.

Abstract: A covering system for vehicles and trailers having a narrow pivot assembly with a moveable arm to help deploy the covering system. The pivot assembly has a gear assembly combined with a spring assembly having the power of multiple springs, which are preferably spiral torsion springs, regarding movement of the arm. The pivot assembly may in turn be mounted in a sliding mechanism for covering various heights of detachable containers.

Abstract: A tarp system with a knuckle arm assembly having a housing on an upper arm with a bent enclosure with a flexible torque shaft or universal joint connector substantially within the enclosure, such as an extruded tube. A first end of the flexible torque shaft or universal joint connector may be used in conjunction with a motor, preferably mounted away from the bend in the enclosure to minimize the envelope of the tarp system around a container of a container of a trailer or rail car. A second end of the flexible torque shaft or universal joint connector is attached to an axle shaft for a roller or the like that is used in conjunction with a tarp.
