Frequently Asked Questions


Disclaimer: We may not post all questions asked due to contextual content.

What are your ramps rated capacity?
Most of our ramps have a 600 lb. rated capacity. Our bariatric models have an 800 lb. rated capacity. PVI Products are tested to a 3X safety factor making the pound for pound, the strongest and lightest ramps available.
What does ADA require for slope ratio?
The least possible slope shall be used for any ramp. The maximum slope of a ramp in new construction shall be 1:12. For additional information on ADA requirements please visit our Ramps Selection Guide.
Can we use a ramp to load a person in the vehicle?
Yes, providing all of the following criteria are met. 1. Since the wheelchair is occupied, Prairie View Industries recommends never exceeding a 2:12 slope ratio (for every 2 inches of rise a foot of ramp will be required). 2. Always make sure a qualified assistant is present when using any portable ramp. 3. Make certain there is adequate head clearance before entering the van. 4. If using a side door entry, make sure there is a minimum of 30" side to side clearance to accommodate the portable ramp.
What is the width of your ramp?
Our standard portable ramps are 30” wide. Our bariatric multifold ramp measures 36” wide.
What are your ramps made of?
PVI uses 6005-T5 and 6063-T5 grade aluminum in our ramping. The portable ramps walking surface is covered with a very high grade/high tack rated adhesive backed non-slip tape. Once applied, it is very difficult to remove. All hardware is zinc plated.
What is the surface of the ramp covered with?
Our portable ramps are covered with a very high grade/high tack rated adhesive backed non-slip tape. Once applied, it is very difficult to remove. The entrance Threshold on our Modular Ramp system is covered with the same material. The actual planking on PVI's Modular Ramp has a grooved surface designed to expel water and provide a safe walking surface.
What ramp would I use to load a wheelchair or scooter into a van?
The Utility Ramp has an extended lip that is designed to rest securely on the interior side of the van. If you are looking for a permanent mounted ramp, we offer both the Rear Door and Side Door Van Ramps. These require mounting to the floor of the van by actually drilling through the van's floor. They will not work on a vehicle that has stow-away-seating.
What is the yellow level on the side of the ramp for?
That is PVI’s visual aid. It is attached to all of the Multifold and Utility Ramps. It is designed for safety as it indicates if the ramp is on a safe slope prior to use.
