According to OSHA, "no ramp shall be inclined more than a slope of one vertical to three horizontal (20 degrees above the horizontal)." The specific maximum slope depends on the type of forklift being used. If you have 'c' and either 'a' or 'b', you can find the arccosine (a/c) or arcsine (b/c), respectively. even where disabled individuals are not the design target.

Synonyms for slope include pitch, angle, rise, incline, or grade. the running slope (1:12 maximum) and cross slope (1:48 maximum) are permitted. Examine how the principles of DfAM upend many of the long-standing rules around manufacturability - allowing engineers and designers to place a parts function at the center of their design considerations. 4:1. 1:48 to allow for drainage. For further building construction, check a dedicated wheelchair ramp slope calculator. For example, if you want a ramp with a specific angle, just enter that value into the proper box (e.g., 55\degree5), fill in the rise field, and the run and ramp length will be calculated for you. In addition, DOT requires detectable warnings on Running Slope: 1:12 maximum slope, or one foot in elevation change for every 12 feet.

I've reviewed and corrected and clarified the question of allowable ramp slope on this page. Ramp Slope Example 1: a ramp with a slope of 1:12. if your ramp is twelve feet long (144 inches) and the rise is twelve inches (12 inches) then the slope of the ramp is 12:144, or simplifying, dividing both sides of the equation by 12, the slope can be written as 1:12 - which meets the desired ADA standard. In this case, you can calculate the run directly from the hypotenuse formula: (more about that formula in our Pythagorean theorem calculator). on facilities located on sites in recognition of separate criteria the Chapter 4: Ramps and Curb Ramps - United States Access Board Personalize your stream and start following your favorite authors, offices and users. Ramp Slope Example 2: a ramp with a slope of 4:12. A ramp is comprised of horizontal sloped runs connected by level landings between runs. Curb ramps can be oriented parallel to sidewalks. A 100% slope is one that is 45 degrees above the horizontal. Along runs and landings, the minimum clear width must be measured If the ramp measures 12 feet long and the rise is 2 feet, you would divide 12 by 2 to get 6, and your ratio would be 1 to 6. To reduce the tripping hazard it was recommended to have a ramp. Therefore, over 11% of all forklifts will be involved in some type of accident each year. We are NOT talking about a 20 degree angle of slope. safety is a top consideration for companies that employ forklift operators. guidelines for public rights-of-ways issued by the Board will address No, the Standards limit the rise of each run (30 maximum), but not the Landings subject to wet conditions must be designed to prevent the For example, ADA requires a minimum slope of 1:20 and a maximum of 1:12. Federal government websites often end in .gov or .mil. You can choose from a straight ramp, a ramp with one turn, or a ramp with a switchback.
