Wheelchair Ramp Guidelines

Wheelchair Ramp Guidelines



The Americans with Disabilities Act (ADA) accessibility guidelines suggest ramp specifications including preferred slopes, width, landings, surfaces, handrails, and environmental conditions. The following method to the actual report on these 4 elements for building, purchasing, and utilizing ramps for wheelchairs:

Wheelchair ramp slopes

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



Wheelchair ramp width and landing

Ramp widths shall not be below 36 inches (915 mm) and apparent. Landings, at both upper and lower, shall be level and accommodate the slope with the connecting ramp. Another added landing features are important:



- Landings shall minimally be as extensive since the ramp.

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

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



Wheelchair ramp handrails

Wheelchair ramp handrail guidelines are suitable for adults. If youngsters are the most crucial users, like in schools, then a following, subordinate rail needs to be provided. If two handrails are being used, one over the other, a minimum distance between rails will probably be 9 inches in order to avoid entrapment. Handrails will be a maximum of 28 inches in the surface of the ramp up with the rail. Ramp rises in excess of 6 inches (150 mm), or level projections superior than 72 inches (1, 830 mm), require railings for sides with the ramp. Handrails are not essential for curb ramps and ramps beside audience seating. Another added handrail features should be made:



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

- If handrails are continuous, they shall extend One foot (305 mm) beyond the end of the ramp, and run equal to the floor.

- The apparent space involving the wall and handrail will be no less than 1 ½ inches (38 mm).

- Gripping surfaces will probably be continuous.

- Handrail ending will be round or returned smoothly to publish, walls, or ground.

- Handrails shall not rotate, or otherwise not move, in their fittings.



Wheelchair ramp surfaces, edges, and environments

Ramps for wheelchairs require surfaces compliant with ADA regulations for such. Ramp edges should be provided if drop offs exist. These edges might be as walls, lips, or any other projections that are at the very least of two inches (50 mm) in height. Construction and design of out of doors ramps for wheelchairs shall not allow for the accumulation of water or snow in the approach or for the ramp.
