Wheelchair ramp

**Design Standards:**
– In the US, the ADA requires a slope of no more than 1:12 for wheelchairs and scooters.
– ADA limits the longest single span of ramp to 30 feet.
– The UK recommends a maximum 1:12 slope for ramps.
– Hong Kong restricts wheelchair ramps to a 1:12 slope.
– Australia mandates a maximum incline of 1 in 8 for wheelchair ramps.

**Vehicle Ramps:**
– Buses, trams, taxis, cars, and vans may have built-in or portable ramps.
– Major automotive companies offer rebates for portable ramps.
– Access to buses and trams may involve a retractable ramp.
– Portable ramps and mobility access equipment are common in new vehicles.
– Ramps facilitate entry and exit for all types of vehicles.

– Adapted automobile.
– Bridge plate mechanism.
– Sidewalk curb wheelchair ramp.
– Wheelchair lift.

Wheelchair ramp (Wikipedia)

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 may predate the wheelchair and are found in ancient Greece.

A wheelchair ramp can be permanent, semi-permanent or portable. Permanent ramps are designed to be bolted or otherwise attached in place. Semi-permanent ramps rest on top of the ground or concrete pad and are commonly used for the short term. Permanent and semi-permanent ramps are usually of aluminum, concrete or wood. Portable ramps are usually aluminum and typically fold for ease of transport. Portable ramps are primarily intended for home and building use but can also be used with vans to load an unoccupied mobility device or to load an occupied mobility device when both the device and the passenger are easy to handle.

Ramps must be carefully designed in order to be useful. In many places, laws dictate a ramp's minimum width and maximum slope.

In general, reduced incline rises are easier for wheelchair users to traverse and are safer in icy climates. However, they consume more space and require traveling a greater distance to go up. Hence, in some cases it is preferable to include an elevator or other type of wheelchair lift.

In many countries, wheelchair ramps and other features to facilitate universal access are required by building code when constructing new facilities which are open to the public. Internationally, the United Nations Convention on the Rights of Persons with Disabilities mandates nations take action to "enable persons with disabilities to live independently and participate fully in all aspects of life." Among other requirements, it compels countries to institute "minimum standards and guidelines..." for accessibility.
