A wheelchair lift, also known as a platform lift, or vertical platform lift, is a fully powered device designed to raise a wheelchair and its occupant in order to overcome a step or similar vertical barrier.
Wheelchair lifts can be installed in homes or businesses and are often added to both private and public vehicles in order to meet accessibility requirements laid out by disability acts. These mobility devices are often installed in homes as an alternative to a stair lift, which only transport a passenger and not his/her wheelchair or mobility scooter.
