A vertical platform lift is a fully powered, semi-automatic way to provide basic, barrier-free access to a building to meet building codes. A key is required to call and run the lift, and the lift only moves between floors when constant pressure is applied to a button. There is no door in the elevator cab, only a door at each landing. A vertical platform lift looks and feels like a traditional elevator because it operates inside a hoistway, but it costs much less. People often use the more general term “wheelchair lift” when referring to this type of lift
