The biggest danger with AC powered stair lifts is that during a power failure, the stair lift will not function. Early versions of stair lifts were all AC powered. Trailing electrical cables presented tripping hazards, and the lifts moved in a jerky, start-stop manner due to the nature of the AC powered motor. At that time there wasn’t much choice because battery technology had not advanced as far as it has today. Today, DC powered stair lifts that only recharge from the household supply of electricity are the most popular lift chair designs. With DC powered stair lifts, if the power goes out, the battery can’t charge, but the lift will still be functional until the battery’s charge runs out. These models are quieter than AC models, too.
Curved stairs are not as safe as a strait set of stairs. Curved stairs get very narrow on one side. A curved set of steps may be difficult to negotiate in an emergency or fire situation. Handrails should be installed on at least one side of the stairs that has two or more risers. Properly configured stair handrails should 34 inches high and they should be designed to comfortably accommodate a person wrapping their hand around the rail. Guardrails also should accompany a handrail system on a properly configured set of steps. The gaps should be only 4 inches wide so that the body of a child can not fit though the openings.
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.
Selecting a stair-lift has now become very easy with the Internet. There are the websites of different manufacturers where not only the product types are shown, but also the features of each of the products are shown so that the costs can be compared relative to the features that each of the products has to offer. In this way, you can easily decide in favour of one of the stair lifts that offer similar features. The Electra-Ride by Bruno stair-lift is an accessibility product that is similar to ThyssenKrupp’s Stair-Glide in certain aspects. The former has all controls, automatic, and is compact and unique in design. The seat height is adjustable so that the seating is comfortable. With its compact design, it is ensured that other people would be able to easily use the stairs even when the stair lift is fixed.
ThyssenKrupp’s Stair-Glide has advanced features, the most significant of which is the hand pendant control; fold up arms and the foot obstruction sensors. In addition to these features, the stair lift also has over speed brake and a joystick control on the arm, which makes the control easier even for people who are not able to use their hands properly. Stairs are composed of stringers, stair treads and stair risers. The stringers are the slanted members on the sides of the stairs which sit on the floor and are tightly attached at the top of the staircase. In most stair construction, there are two stringers installed on each set of steps. The stair treads are the sections in which you step on to travel up and down the stairs. Stair treads are usually made of wood.
