Stair Case Lift

A stair lift is a mechanical device for lifting people, typically those with disabilities, up and down stairs. For sufficiently wide stairs, a rail is mounted to the treads of the stairs. A chair or lifting platform is attached to the rail.The most common type of stairlift involves a straight rail that runs up a domestic staircase. The rail is usually made from extruded aluminium or steel. The rails come in various cross-sections and, depending on their length, can weigh more than 30 kg. The rails are attached to the stair risers with metal brackets.
