Curb ramp detectable warnings are required only Throughout this article series and in other documents you may see slope expressed as unit rise over unit run, such as 4:12 (4 inches of vertical rise in 12 inches of horizontal run), or you may see the same slope expressed as a percent (unit rise divided by unit run), or slope expressed in angular degrees. That is not a service ramp to me. This link has some very helpful information for loading docks: All the dock equipment suppliers (Kelly is another one) have information on ramp design. curvature and slope result in uneven surfaces that makes wheelchair In this paragraph, we'll take a closer look at ADA ramp slopes.

Building safety features into loading dock ramps can also help mitigate these issues. Side flares can be provided to prevent tripping hazards. Recommendation: Provide edge protection along the sides of built-up curb ramps to prevent tipping hazards. Other handrails specifications, including those for height, clearance, gripping surface, and cross section, apply. For example a steeper slope may be permitted on non-access ramps.
