Adjustable brackets are designed to be user friendly, fast, accurate and above all, strong. In fact, the brackets do most of the work. They automatically adjust to the exact rise and run and are approved as "adjustable joist hangers". This allows the risers to act like floor joists, carrying the load across the stair between the stringers which means only two stringers are required for stairs up to nine feet in width. Additionally, each stringer requires only three to four end cuts (only six to eight cuts per stair!)....significantly eliminating dozens of saw tooth cuts which are often required for conventional stringers.
While the maintenance of mobility in the event of a power outage is a huge advantage of a DC stair lift system, that advantage is tempered by the cost of replacing batteries every 12 to 18 months, which can run up to $100 a pop for most stair lift batteries. On the other hand, DC stair lifts make less of a demand on the home electricity system, meaning that electric bills will be somewhat lower for DC powered lifts. The batteries of a DC powered stair lift charge in one of two methods: station charging or the use of a charge strip. With station charging, permanent charging stations are positioned at each end of the rail. Charge strips allow the lift to charge at any point along the track. Today’s rechargeable batteries are reliable and hold a charge better than old models. The typical stair lift battery will stay charged through about 8 trips up and down the track, though it will vary based on how long the staircase is and how heavy the person it is transporting is.
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.
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.
