Ramps for the disabled measurements

The construction of a ramp for the disabled is one of the options available and contemplated in the Technical Code, to facilitate accessibility for people in wheelchairs. But is it possible to build any type of ramp? How should an adapted ramp be? How can we calculate the length and slope to facilitate access for people with mobility problems?

But when installing or building a ramp, we must take into account a series of fundamental factors to make it accessible, usable and safe. This is achieved by building a ramp that complies with current regulations. When choosing or building ramps for people with disabilities, the most important thing is to take into account aspects such as slope, maximum length, clear width and dimensions of the ramp.

The first thing to consider is that the longer it is, the lower the slope, the easier it will be to climb. For a slope to be easily climbed by a wheelchair user (for example), it should not exceed 10%.  We must also take into account the architectural barrier to be overcome, the environment, the different existing accesses, and above all, the geometric conditions and use of the spaces, in order to ensure the usability of the ramp and the rest of the spaces and accesses for everyone. It is also convenient to evaluate if the ramp is going to be permanent or temporary, if we need portability or not.

Maximum slope for handicapped ramp

I often come across impossible ramps, that typical ramp that only serves to shut mouths but in reality cannot be used safely and certainly no one in their right mind would dare to go up or down with a wheelchair, a baby cart or even a shopping cart.

Here is an example that I recently found in a health center where, inside, they had made a ramp to save 6 steps. In addition to the fact that the slope is steep and the chosen pavement had to be slippery (because later they had to put anti-slip strips all over the ramp), if you notice, at the door there is a step of about 18 cm that has no ramp at all.

It is also important to remember that ramps must be free of obstacles. Unfortunately it is common to find ramps invaded by furniture and when someone who needs it arrives, they have to levitate (I wish it were possible), wait for someone to empty it or simply, and this is the most common thing, go to another place.

What is the maximum allowable slope? Ramps with a slope greater than 12% are not allowed. In accessible routes the maximum slope is reduced to 10% (depending on the length of the section, a certain slope of the ramp cannot be exceeded).

Maximum slopes depending on the length of the ramp The technical code in its basic document DB -SUA (Safety of use and accessibility), regulates that the maximum slope of a ramp must be 10% to be able to consider the itinerary as accessible, being 8% and 6% in itineraries of lengths greater than 3 and 6 m. The ramps that belong to accessible itineraries, whose slope will be, as maximum, 10% when its length is less than 3 m, 8% when the length is less than 6 m and 6% in the rest of the cases. If the ramp is curved, the maximum longitudinal slope shall be measured on the most unfavorable side.

Types of handicap ramps

For handrails to be effective, they must be within reach of a person using the stairs. Therefore, in addition to providing handrails on the sides of stairs, intermediate handrails are required so that no part of the stairway has more than 30 inches (760 mm)-or 44 inches (1120 mm) for existing stairs-of horizontal reach from an available handrail. The 30-inch distance from a point on a new stairway to the nearest handrail is based on the fact that people can only reach approximately 24 inches to one side to grasp a handrail and that a person’s arms extend from the side of the body, not from the centerline.

The Code does not expect, nor does it want, a person to have to reach too far, or move horizontally or vertically across or down stairs without a handrail available for stability. It is not the
