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.

Dual mode, easy to service tarp

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.
