The Complete Handbook of Stair Lifts

Chapter 1: Understanding Stair Lifts

The Machine on the Steps

A stair lift is a single-person elevator that travels along a rail mounted to the steps or the adjacent wall. It exists for a simple reason: thousands of people, every day, need to move between floors of a home or building and cannot use the stairs. Some have undergone knee or hip replacement and face a temporary recovery period. Others have progressive conditions such as multiple sclerosis, muscular dystrophy, or Parkinson's disease. Many are simply older adults whose leg strength and balance have declined to the point where a flight of stairs is an obstacle with real risk of a fall.

Stair lifts are not new technology. The basic design has been around for nearly a century, and the fundamental architecture has not changed much: a powered carriage rides on a rail, driven by an electric motor, with a seat that faces outward and a footrest that folds up when the chair is not in use. What has changed over the decades is the quality of the engineering, the materials, and the safety systems. A modern unit from a reputable manufacturer is reliable enough to run tens of thousands of cycles over a decade or more. The same cannot be said for the inexpensive imports that have flooded the market in recent years, which is why a professional needs to understand what separates a sound machine from a problematic one.
