Best Answer

A wheelchair ramp should have a very gradual rise. The grade should be 1" rise for every foot of space (1:12). This is in order to ensure that the ramp is easy for the person in the wheelchair to go up and to make sure that they are not in danger of going down too fast.

Moveable Wheelchair Ramps?

While permanently constructed wheelchair ramps are becoming more and more a part of our public architecture, portable, temporary or semi-permanent ramps are equally important in making the world accessible to all. Portable wheelchair ramps are usually foldable as well. Ramps can be found that will fold into several configurations. Many fold into a suitcase type arrangement. Weight is a major consideration for a portable ramp. Ramps are available in lightweight aluminum, often a good choice because it is non-corrosive. However, very lightweight aluminum can wobble or bend. Sturdiness is another important issue. Weight specifications must be heeded. Ramps should always be tested before purchase for a specific wheelchair and occupant for weight and comfort issues. Portable wheelchair ramps are used to bridge steps where needed and for entrance into vans and SUVs. Wheelchair ramps, whether permanent or portable, must often be longer than might first be anticipated in order to allow the slope to be safe for use. To conform to the ADA slope requirement, a ramp can be no steeper than a 1:12 ratio of height to length. For ramps into vehicles, however, that ratio may not be practical given parking and other limitations. Electric wheelchairs can usually navigate the steeper grade, but the recommended maximum gradient for specific wheelchairs must be noted. Many vehicle ramps can be mounted to the floor for a more permanent, and perhaps sturdier, arrangement. Threshold ramps are another kind of portable ramp. They accommodate a wheelchair’s access over a door or sliding door entrance. Threshold ramps can be used, as needed, on one side of the doorway or both. Where residential access needs are greater than can be solved by portable ramps, temporary or semi-permanent ramps can be used. These allow for quick and easy installation and removal. While portable ramps generally do not have handrails, temporary or semi-permanent ones usually have them for safety. These ramps come in single pathway versions as well as modular types that can be configured as necessary.
