It is not always easy for people who are older and those that suffer from mobility related diseases to climb the stairs. Often the stairs are something that is avoided for these people, and for good reason. A fall down the stairs is the leading cause of hospitalization and accidental death among those who are over the age of sixty-five, so it is no wonder that many are wary around the stairs. To improve the ability to independently use the stairs and reduce the risk of injury, a stair lift is commonly installed to the stairs. A stair lift is a mobility lifting aid that quite literally carries a person up and down the stairs. A track is secured to the stairs, then a chair, or in some cases, a platform is sent up and down the track carrying a single rider.
How is this possible with only two stringers? The adjustable brackets are ICC/ES tested and approved as joist hangers. The risers are made structural (2x8’s), attaching to the brackets and spanning across the stair like load bearing joists. This structurally superior system has been tested with breaking strains in excess of 1,200 lbs. per sq. ft. Once the risers and treads are attached, your stair is complete. The result will be a stair that is accurate, extremely strong and "you built that stair".
Over the past several years, much has been done to address deck and stair safety issues, but we still have a long way to go. One glaring example of the failure in deck and stair safety protocol is the industry standard of permitting "hot dipped galvanized" anchors, screws, hangers and other hardware to be in direct contact with ACQ, pressure treated wood. The galvanic corrosion created between the high copper content of the wood and the galvanizing is so severe that the normal industry standard of G90 galvanizing will corrode in as little as 12 months and G185, such as Z-Max® can be gone in 24 months. The industry (including code officials) has adopted G185 as a fall back position with no engineering testing available to substantiate the validity or longevity of this adoption...this is a "knee jerk" reaction and is an accident waiting to happen. Without a barrier between the pressure treated wood and galvanized hardware, serious corrosion is inevitable.
The Summit Stair Lift: This is a low cost home stair lift. The company only makes straight stair lifts. The Summit chair lift is made to be a no-frills but reliable handicap stair lift. It uses technology that is now considered old-fashioned by most leading stair lift manufacturers; it uses a cable system rather than rack and pinion to drag the chair along the track, and the Summit stair lift is mains powered rather than battery powered. Other manufacturers switched to rack and pinion battery powered stair lifts because they give a smoother ride. You do get basic safety systems with the Summit stair lift such as a sensor on the footrest to detect obstacles, a seat belt and cable tensioning. Won’t you won’t get the more sophisticated safety features offered by other manufacturers. All in all, the Summit stair lift is for those on a small budget.
