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.
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.
