What is the maximum slope of a handicap ramp?

What is the maximum slope of a handicap ramp?

Maximum slope for hand-propelled wheelchair ramps should be 1″ of rise to every 12″ of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5″ rise to 12″ length (7.1 degree angle; 12.5% grade). Minimum width should be 36″ (inside rails) – (48″ is ideal).

What is the maximum length of a handicap ramp?

Following the ADA ramp requirements, the maximum rise for a single ramp run is 30 inches. That means that maximum length is 30 feet, so one additional platform landing is required for every additional 30 feet of ramp.

What slope is not considered a ramp?

Ramps less than 6″ high do not require handrails. The second way is to keep the slope less than 1:20 or 5%. With a slope less than 5% it is not considered a ramp and therefore does not need handrails.

What is the minimum width of an ADA ramp?

Ramps shall be a minimum of 48 inches wide with level landings at both the top and bottom of every ramp. (CCR, Sections 11B-405.5, 11B-405.7 and 11B-405.7.

How steep can a car ramp be?

If there are no rules about it in the jurisdiction, the practical max is 20% for most types of vehicles… and you’ll want the two-stage transitions mentioned above by Gabriel if you’re that steep.

How steep can an ADA ramp be?

The ADA provides good direction about ratios for wheelchair ramp slopes. The commercial and public facility standard for slope is 1:12 (in inches) or about 5 degrees of incline. For those building ramps at home, the ratio can be as steep as 3:12 or almost 15 degrees.

What does a slope of 1/12 mean?

For a ramp the maximum running slope allowed is 1:12. That means for every inch of height change there should be at least 12 inches of ramp run.

What is the steepest angle you can walk up?

The steepest slope that can be walked up is perpendicular to the force of gravity. In mathematical terms, this means that the angle between the surface and the direction of gravity must be 90 degrees for someone to be able to walk up without using any other energy than that provided by gravity.
