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 stair is now laid on its back and (starting from the bottom step) the treads are laid in position, fitting perfectly without gaps. As each tread is positioned it is attached to the rear riser. Once all treads are positioned, the stair is laid on its side again and the end screws through the brackets are inserted. The fasteners attaching the tread to the top of the rise may be inserted as blind screws (using pocket holes in the risers) or blocks from the underside or simply using finished nails from the top.
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.
Starting with two parallel 2x6 stringer members, the adjustable brackets are first positioned using a spacing tool and then attached to each member with a single "pivot screw". For finished interior stairs, the stringers may be "paint" grade or "stain" grade but will have a tongue and grove or spline milled into the parallel mating surfaces so that once the brackets are adjusted, the mating surfaces will be pushed together to form a continuous, decorative, one piece knee wall stringer. The remaining screws are inserted and the end cuts are made. All the risers and treads are now square cut to the exact length using a chop saw. It is recommended that a stop is used for accuracy and efficiency. The treads are usually cut slightly shorter than the risers (1/64") for fit. For fast assembly it’s best to first pre- assemble the stair and then lift into position whenever circumstances permit.
In fact, the best time to add a stair lift system may be before it is actually a requirement. There are plenty of seniors who may not be disabled, but who experience intermittent conditions, such as an arthritic knee or hip, that make climbing stairs a challenge some of the time. Stair lifts can be installed in straight or curved staircases. Most models today run on rechargeable DC battery packs that hold a charge for around 8 to 10 trips up and down, depending on the length of the track and the weight of the person it is transporting. Some of these battery packs have chargers mounted next to the top or bottom of the lift track, while others are able to recharge from anywhere along the track. DC powered stair lifts are the preferred style today because they still work (for a while anyway) if the AC power to the household is cut. Many seniors, through no fault of their own, lose the ability to go up and down staircases with agility. And many of them have strong emotional ties to the house in which they live. A stair lift can make the difference between allowing a senior to have significant independence of daily living and having to making the difficult choice of selling a beloved home.
