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.
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.
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.
