Wheelchair Ramp Guidelines



The Americans with Disabilities Act (ADA) accessibility guidelines suggest ramp specifications offering preferred slopes, width, landings, surfaces, handrails, and environmental conditions. Another area to the idea listing of these factors for building, purchasing, and using ramps for wheelchairs:

Wheelchair ramp slopes

A ratio of rise over run can be used to define ramp slopes (e. g. 16 inches of level run for each 1 inch of upright rise can be expressed as 1:16). The preferred ADA ramp slope is between 1:16 and 1:20. New construction slopes shall not exceed 1:12. Slope alone is not only issue to take into consideration; ramp distance and maximum rise can be minimized. Maximum rise shall not exceed 30 inches (760 mm), and ramp distance should avoid lengths higher than 30 feet (9 m).



Wheelchair ramp width and landing

Ramp widths shall 't be less than 36 inches (915 mm) and apparent. Landings, at both top and bottom, should be level and accommodate the slope in the connecting ramp. The following added landing features are essential:



- Landings shall minimally be as extensive since the ramp.

- Landing length shall at least be 60 inches (1, 525 mm).

- Landings which has a direct turn need a at least 60 x 60 inches (1, 525 mm x 1, 525 mm).



Wheelchair ramp handrails

Wheelchair ramp handrail guidelines are for adults. If children are the most important users, for example in schools, then the following, subordinate rail needs to be provided. If two handrails are employed, one across the other, a nominal amount distance between rails will be 9 inches to stop entrapment. Handrails will be no more than 28 inches through the top of the ramp to the peak of the rail. Ramp rises higher than 6 inches (150 mm), or level projections superior than 72 inches (1, 830 mm), require railings for both sides with the ramp. Handrails aren't necessary for curb ramps and ramps alongside audience seating. The subsequent added handrail features should be made:



- Each side of ramp segments require handrails; where doglegs and switch - backs exist, the inside railing should be continuous.

- If handrails are continuous, they shall extend 12 inches (305 mm) after dark end from the ramp, and run equivalent to the bottom.

- The apparent space relating to the wall and handrail should be at the very least 1 ½ inches (38 mm).

- Gripping surfaces will probably be continuous.

- Handrail ending shall be round or returned smoothly to create, walls, or ground.

- Handrails shall not rotate, or else move, inside their fittings.



Wheelchair ramp surfaces, edges, and environments

Ramps for wheelchairs require surfaces compliant with ADA regulations for such. Ramp edges shall be provided if drop offs exist. These edges may be by means of walls, lips, or another projections which are at a minimum of 2 inches (50 mm) in height. Design and construction of outdoor ramps for wheelchairs shall not accommodate the accumulation of water or snow on the approach or on the ramp.
