Electric Wheelchair Ramp Slope

Run is not the length of the ramp.

Electric wheelchair ramp slope. A 24 rise requires a minimum ramp length of 24 288 24 divided by 1. Learn the correct measurements of a properly constructed wheelchair ramp. 6 rise 52 ramp run 115 or 11 5 grade. Maximum slope for power chairs should be 1 5 rise to 12 length 7 1 degree angle.

To determine the percent of grade. Residential applications can use a 2 12 slope ratio if space is an issue but only if an assistant is present to help push the wheelchair or to help a person walking on the ramp. Disability systems recommends a 1 12 slope on most applications. Ada guidelines require a minimum 5 x 5 flat unobstructed area at the top and bottom of the ramp.

For commercial use when somebody is sitting in the wheelchair or scooter while it climbs the ramp ada recommends a 1 12 slope which means that every 1 of vertical rise requires at least 1 12 of ramp length 5 degrees of incline. Maximum slope for hand propelled wheelchair ramps should be 1 of rise to every 12 of length 4 8 degree angle. For instance a 30 inch rise requires a 30 foot handicap wheelchair ramp. Modular ramps modular ramps are built for both home and commercial access.

Divide rise by the run of ramp. Wheelchair ramp slope and percent of grade information percent of grade formula. For commercial public access a 1 12 ratio is required check your local codes.
