Stair lifts are devices that are attached to the treads of staircases to safely move someone who is elderly or disabled up or down the stairs. They consist of a track, usually made of aluminum, a chair attached to the track, and the electronic controls that make the chair move up or down the track. Stair lifts are powered by alternating current (AC), which is hooked up to the household electrical system, or with direct current (DC), which uses a battery that recharges from the household electrical system, and does not require use of home electricity to work properly.
The best method which works is the rack and pinion method. The drawbacks of the other methods are the one which uses cable is a lot more expensive while the one driven by chain creates sound while pulling the chair. The stair lift rental works with the help of a button. You just need to sit in the chair and press the button and it will take you up the stairs. The stairs are one of the most important parts of any household. It serves as the heart of any house since it connects all its parts and makes it distinguished from other houses. There are different kinds of stairs like spiral, straight or curved but all of these have the same things in common. They have the same purpose and the same stair parts.
Proper stair design has a maximum rise of eight inches, a minimum run of nine inches and a minimum tread width of 9.25 inches. A safe and properly configured stairway should be at 34 inches wide. As a rule the wider steps are safer then narrow stairs. There needs to be adequate headroom above the set of stairs. The required headroom is at least 6 foot 6 inches. When there is a door at the top of a set of steps, it should open away from the stairs for safety reasons. If a door opens toward the stairs a landing is needed so a person opening the door will not be able to push someone on the stairs.
