This assistive device is used to move a wheelchair upstairs or into a building.

A ramp is designed to facilitate the movement of a wheelchair upstairs or into a building by providing a sloped surface that allows individuals using wheelchairs to navigate inclines safely and easily. Ramps can be constructed in various lengths and angles to accommodate different building designs and accessibility needs.

In contrast, a stairlift is a motorized device that transports a person up and down stairs while seated in a chair attached to a rail. An elevator, on the other hand, is a compartment that moves vertically between floors to assist individuals with mobility challenges but requires a predefined structure in the building to operate. A hoist is a device used to lift or lower individuals, often used in medical or caregiving settings, but it does not assist with moving on stairs or entering a building. Each of these alternatives serves different purposes but does not directly facilitate the task of moving a wheelchair up stairs like a ramp does.
