A wheelchair ramp is an inclined plane installed in addition to or instead of stairs. Ramps permit wheelchair users, as well as people pushing strollers, carts,
or other wheeled objects, to more easily access a building. Wheelchair
ramps come in a number of varieties each intended for a different
purpose. There are permanent, semi-permanent and portable. Permanent
ramps are designed to be bolted or cemented in place. Semi-permanent
ramps rest on top of the ground or cement pad and are commonly used for
the short term. Portable ramps are lightweight, usually aluminum and
typically fold for ease of transport. Wheelchair ramps are also
available in other materials such as a steel and wood. Wood ramps are
cheaper but are not as durable. Steel ramps are durable but quite
heavy. [1]
Ramps must be carefully designed in order to be useful. Many
jurisdictions have established standards for permanent wheelchair
ramps. For example, they may specify the minimum width of a wheelchair
ramp is 36 inches, and the slope
must not be steeper than 1 inch of rise for every 12 inches of length.
A less steep rise can be easier for a wheelchair user to navigate, as
well as safer in icy climates.
Wheelchair ramps (or other ways for wheelchair users to access a building, such as a wheelchair lift) are required in new construction for public accommodations in the United States by the Americans with Disabilities Act.
There maybe many kinds of Wheelchair Ramps,such as aluminum ramp.
