RAMP SELECTION GUIDE

If you need any help determining the correct size ramp to fit yourneeds, give us a call at 1-866-270-7548 and one of ourrepresentatives 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 verticalmeasurement from the ground to where the top of the ramp will sitwhen in use.

Your chair/scooter manual will have a recommendation for whatangle 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 1foot 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 strongarmed manual wheelchair operator, or with an able assistant pushing. Thiswill also work with powered chairs and scooters.

-A 3:12 slope, or 1 foot of ramp for every 3" rise works for unoccupied powerchairs and scooters, however you should check your chair's owners manualfor 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 thestep/landing/tailgate/door jam before using the ramp. It may be necessaryto secure the ramp with pins/screws

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