These are devices that are designed for providing those in wheelchairs, or persons with other mobility impairments, with a way of getting from one level in a building to another.
Travel is limited to open areas such as atriums.
An inclined wheelchair platform lift goes up on an angle, usually from one floor to the next. A vertical wheelchair platform lift runs vertically from one level to another to a maximum vertical travel of 12 feet. These units are not allowed to penetrate a floor. Both types of units are limited to a maximum capacity of 750 pounds and no more than 18 square feet of net floor space. Equipment that exceeds these limits are required to meet more stringent safety standards.
