A concrete wheelchair ramp A portable wheelchair ramp. 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, or navigate between areas of different height. Ramps for accessibility ...
(This is the angle α opposite the "rise" side of a triangle with a right angle between vertical rise and horizontal run.) as a percentage, the formula for which is which is equivalent to the tangent of the angle of inclination times 100. In Europe and the U.S. percentage "grade" is the most commonly used figure for describing slopes.
Wheelchair ramp, Hotel Montescot, Chartres, France Demonstration inclined plane used in education, Museo Galileo, Florence.. An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load.
The bridge plate extends from the vehicle to the platform, which must be raised to close to the level of the floor of the vehicle so that the wheelchair need not travel over an excessively steep ramp (in the United States, the Americans with Disabilities Act specifies that the slope must be no more than 1 inch of rise for every 12 inches of ...
S = slope, θ = angle of slope (inclination). The velocity on the flat terrain is 5 km / h, the maximum speed of 6 km / h is achieved roughly at -2.86°. [5] On flat terrain this formula works out to 5 km/h. For off-path travel, this value should be multiplied by 3/5, for horseback by 5/4. [1]
Fold-up ramps fold in half and stow upright next to the side passenger door in a side-entry configuration or inside the rear access doors in a rear-entry configuration. Fold-up ramps present a lower ramp angle than in-floor ramps; however, in side-entry configurations, they are in the way of the passenger entrance when stowed.
Passengers requiring a WCHR (Wheelchair on Ramp) status are able to use stairs/steps, walk short distances and are able to make their way to their assigned seat but may require mobility aids or other forms of assistance for more strenuous activities like climbing stairs and walking long distances.

The conventional layout for a typical domestic stair lift is to have the seat at right angles to the rail so the user travels "sidesaddle". At the top of the staircase the seat can be swiveled, commonly through around 45 degrees or 90 degrees, then locked in place to allow the user to alight from it onto a landing.
