RAMP SELECTION GUIDE

If you need any help determining the correct size ramp to fit your needs, give us a call at 1-866-270-7548 and one of our representatives will be happy to assist you.

To determine the appropriate length of ramp for your application, you will first need to identify the slope (rise).  This is the vertical measurement from the ground to where the top of the ramp will sit when in use.

Your chair/scooter manual will have a recommendation for what angle is appropriate for loading/unloading or using a ramp to get up stair sets, etc.

-The ADA (Americans with Disabilities Act) recommends a 1:12 slope, that is 1 foot of ramp for every 1" of rise.  This will work for all manual (self-powered) wheelchairs.

-A 2:12 slope, or 1 foot of ramp for every 2" rise is recommend for a strong armed manual wheelchair operator, or with an able assistant pushing.  This will also work with powered chairs and scooters.

-A 3:12 slope, or 1 foot of ramp for every 3" rise works for unoccupied power chairs and scooters, however you should check your chair's owners manual for maximum slope guidelines as this slope may cause  problems with high-centering at the top of the ramp for chair/scooters with low clearance. 

Recommendations:

1. Always have a qualified assistant present when using any portable ramp.

2. Never exceed a slope greater than what is recommended in your chair/scooter's operation manual.

3. Always make sure the ramp is secured at the top on the step/landing/tailgate/door jam before using the ramp.  It may be necessary to secure the ramp with pins/screws

4. Make certain there is adequate head clearance prior to loading an occupied chair or scooter into a vehicle.

5. Always use your lap belt.

The following charts will help you determine the length of ramp based upon the maximum slope allowed.
