A Platform Lift is primarily designed to give reasonably priced access to people who have difficulty with a staircase.
On Platform Lifts which serve between 2, or more floor levels, a fully enclosed shaft (rectangular tube) is provided which has relatively smooth internal walls. An L shaped platform moves up and down the shaft carrying a wheelchair and/or people.
The shaft can usually be constructed with either solid or glazed walls, or even a combination of both.
