A Platform Lift is primarily designed to give reasonably 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
These are domestic lifts similar to the commercial elevators that we all use in shopping centres and high rise commercial buildings. They consist of a cage or car travelling inside an enclosed shaft.
This can be a self supporting unit that can be fitted either inside or outside the house, or it could be wall mounted unit with a built-in shaft.
