AutoTarp System

Valid’s AutoTarp system was designed to reduce the potential for workplace injuries sustained by chip truck drivers during the tarping process. The system can be retrofitted to multiple trailer sizes, and is able to integrate with standard rigging equipment. Nesting inside the trailer without adding height, length, or width, it also meets CVSE (Commercial Vehicle Safety and Enforcement) regulations.

Designed to be as light and unobstructive as possible allowing for larger load volumes and simple button-controlled operation. It is strong enough to withstand the challenges of the environment. Above all, it keeps drivers safe and on the ground.

Frequently Asked Questions

How does the system work in a high wind environment?

The tarp is secured to the trailer on the passenger side with chains and bungees, not ‘sealed’ to the trailer top rails, this allows the wind to flow through and out the bottom of the tarp.

Does the system work in a low temperature environment?

The Valid™️ AutoTarp has been successfully field tested in -35°C plus wind chill temperatures.

Are there any accidental damages that occur during loading?

The Valid™️ AutoTarp swingarms are mounted in the trailer. We recommend heaping the load, do not have the loader operators “tamp” the load down. The tarp is designed to go over heaped loads. This greatly reduces the risk of crossmember damage due to loader buckets.

Will the tarps open if covered in heavy rain or snow?

Yes, but caution must be used.

Do the cables hang down or pile up on the ground on the passenger side when the tarp is open?

The passenger side cables and bungees are installed so that they are about 1’ – 2” above the ground when the tarp is open. Tie downs can be used to move the front and rear chains away from the wheels.

Will the cylinder mechanism (the orange parts) prevent the driver from properly loading the front and back of the trailer?

The swing arm frames are wide enough that product flows through. What customers are doing is taking advantage of how high the tarp goes over a heaped load. They load more in the middle and let the product settle. No loss of payload should occur if loaded this way. The other advantage of loading more in the middle is no loader related damage.

How much does the system weigh?

The system will add approx. 550 – 600lbs per trailer.

Is it electric, pneumatic, or hydraulic?

The swing arms are equipped with a 3000lb electric actuator that is powered by a 24V ultra-capacitor system.

Is there a manual override that will enable the driver to get the tarps opened or closed in a manual fashion if there are system malfunctions?

Yes. The owner’s manual has a step-by-step procedure on how to manually open or close the system. The system is also capable of running one arm at a time in case of an obstruction.

Can the system be installed and serviced by our technicians?

Yes. Installation training can be arranged. Please contact us for more information.
