A system can include a motor for driving a tarp roller across a trailer for covering and uncovering the trailer with a tarp. The system can also include a power supply for powering the motor. The system can further include a sensor coupled with the motor for sensing power consumed by the motor as the motor is powered to drive the tarp roller across the trailer. A controller can be communicatively coupled with the sensor and operatively coupled to the motor and the power supply for switching an energy characteristic of the power supplied to the motor from the power supply between a first characteristic associated with a lower torque and a second characteristic associated with a higher torque by monitoring the power consumed by the motor and switching the energy characteristic when the power consumed by the motor indicates the lower torque is insufficient to drive the tarp roller.

Apparatuses described herein relate to improving the prevention of cargo movement during vehicle travel. In one embodiment, an apparatus for securing cargo within a vehicle includes a bladder coupled to an underside of a cover that extends over a cargo area, where the bladder faces the cargo area. The apparatus includes a supply device coupled with the bladder via a connecting member to expand the bladder into contact with the cargo within the cargo area.

The invention relates to a tarp spooling device, mainly comprising a motor, a reduction gear set, a bevel gear set, a tarp reel, and a clutch, wherein the reduction gear set is coupled to the rotor shaft of the motor, the bevel gear set is coupled to the reduction gear set, the tarp reel is coupled to the bevel gear set, and the clutch is coupled between the reduction gear set and the bevel gear set. When the motor is activated, the rotor shaft drives the tarp reel to rotate through the reduction gear set, the bevel gear set, and the clutch; and when the motor is deactivated, the clutch locks the tarp reel, and the tarp reel is unable to be rotated. When the motor is deactivated, the clutch is self-locked, and only when the motor is activated again, the tarp reel can be rotated again.

A cover for covering a car or luggage on top of a car is described. The cover is made of a stretchy material such that it can expand to tightly fit the size and shape of a large variety of items or vehicles. Thus, the material composition as well as cover layers are crucial in obtaining the optimal balance of flexibility and protection. In many embodiments securing mechanisms are provided around the base of the cover as well as over the top of the cover to aid in securing the cover over the items or vehicle. In some embodiments a lower cover is provided which sits under items on top of a vehicle and protects the roof of the vehicle from the items.

A drive system for operation of a roll top cover for covering a cargo bed of a vehicle enables improved and smoother roll top cover movement. The drive system includes: an elongate housing that defines a longitudinal axis and first and second ends, the housing including an axially extending aperture for receiving the roll top cover therethrough; first and second receiving plates disposed transversely within the housing at the respective first and second ends thereof, the receiving plates comprising opposed spiral-shaped slots extending therethrough, each of the spiral-shaped slots having an open end proximally and a closed end distally; and a drive shaft assembly disposed within the housing and extending axially between the first and second ends thereof; wherein the drive shaft assembly is adapted for being operably connected to a drive chain and driving movement thereof within the spiral-shaped slots during operation of the roll top cover.
