Based on the measurement you provide for the ramp rise (i.e. NOTE 1: Ramps might be required for use by persons without disabilities, for example, persons pushing trolleys who require ramps as an alternative to stepped access. WHY WE LIKE IT: Made from durable all… This is because there is no set standard for the height of a home's landing. Permanent ramps are designed to be bolted or otherwise attached in place. Now just try our ramp lengh calculator to help you determine the “Slope Angle” and lengh of the ramp needed. A less steep rise can be easier for a wheelchair user to navigate, as well as safer in wet or icy conditions. You can also contact them through their website at www.qasa.co.za or read the article below to find out about Accessible Features & the other companies in South Africa that can assist you. In truth, there is not much to calculate. Mechanical ramps can be used in large public buildings but are not recommended for use by persons with physical impairments. Problem: This naturally presupposes a corresponding ramp length. If you are looking for maximum slope for wheelchair ramp, than you are in the right place. What is the Proper Wheelchair Ramp Slope Measurement? A 2:12 ratio gives is not too challenging for wheelchair users and cuts the length of a potential ramp in half. While the ADA requirements only apply to commercial ramps, many home access professionals adhere to the 1:12 slope ratio for residential ramps as well. (eg: 6" rise / 52" ramp … Table 2 — Ramp requirements between landings. Generally Recommended Wheelchair Ramp Slopes handrails shall have an elliptical gripping surface profile that is approximately 50 mm wide and 40 mm deep, or a circular profile of diameter not less than 35 mm and not more than 50 mm; the height to the top of a handrail from the nosing of the tread of the stairs or from the surfaces of a ramp shall be in the range 900 mm to 1 000 mm and shall remain consistent along the length; handrails shall be securely fixed and shall be rigid; the surface of the handrail and wall, or any other surface adjacent to them, shall be free of any sharp or abrasive elements; the clear width between a handrail and an adjacent wall shall be at least 60 mm; handrails shall extend 300 mm horizontally beyond the top and bottom of the ramp or stairway (see figure 12 and shall return to the supporting structure or shall be finished with a positive return, and the minimum dimensions for landings on escape routes as required in SANS 10400-T shall be maintained; handrails shall be continuous between landings where this does not create a hazard; 19. handrails shall be supported centrally from below with not less than 50 mm between the underside of the handrail and the top of the support; where a stairway is wider than 2,4 m, a handrail shall be provided at no more than 2,4 m intervals. //assets.adobedtm.com/launch-EN0fcc4bdb8a334bbba4df0dd9dc3bafb0.min.js. Run is not the length of the ramp. One of the largest safety measures concerns the wheelchair ramp slope. As a general rule when using portable wheelchair ramps most ramp manufacturers recommend a maximum slope no steeper than 1:12 for independent use and 1:8 for assisted use over shorter distances. A 1:12 ratio is too steep for some people to navigate, and a lower slope may be required for some public buildings. Access Audits involves inspecting the built environment to determine compliance with legislation to enable access that is easier, friendlier & healthier to use by everyone. Let's keep this easy and mostly talk about simple ratios for ramp slopes. 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).
