Article  Understanding the Intricacies of the Stairlift While the stairlift is a mechanical device utilized to assist those who are disabled or otherwise impaired when it comes to traveling up and down stairs, this definition can often oversimplify these important apparatuses that are potentially more elaborate than meets the eye. Many of the first users of commercially available stairlift models were individuals who had suffered from polio, as did the former president of the United States, Franklin D. Roosevelt. This was a dangerous disease that had incapacitated a number of individuals to varying extents. Marketed in the U.S. initially in the 1930s, these first stairlifts were highly successful. Over time, the market for such pieces of equipment would expand, today heavily including the elderly and handicapped. Capable of being used both indoors and outdoors, the stairlift mechanisms may be purchased with a number of amenities to make the use of such gadgets as comfortable as possible to those who need to use the devices. Straight rail stairlifts are the most common construction when it comes to the stairlift. In most instances, these types of mechanisms are installed in residential areas where straight stairs are in place in the building. Fixed to the steps’ staircase, the straight rail stairlifts are easier than curved rail stairlifts, for example, to install and manufacture since they do not require as precise and intricate measurements and placements. The most common design for stairlifts is the wheelchair platform. With a heavy construction, this type of stairlift known as a wheelchair lift is able to accommodate the carrying of an individual on a wheelchair. Many models offer a protective edge to the platform in order to keep the wheelchair from shifting off the platform while in transit. Engineering of these models varies, but can include aluminum extrusions on the rail, steel cable, chains or rack and pinion systems. Custom improved weatherproofing can help make outdoor stairlifts a reality. Almost all stairlifts are powered by alternating currents, AC, or direct currents, DC. Early stairlifts primarily used motors powered by alternating currents, which required a cable carrying the current alongside the rail to make it run. However, more current stairlift models utilize rechargeable batteries and direct current power options. Many users are pleased to know that in the event of a power outage, stairlifts running on direct current batteries will continue to function as long as they have a sufficient charge, unlike their alternating current counterparts. Most stairlift machines are directed by users with the use of a remote control. This is often installed on the arm of the stairlift. Models typically feature either a switch or a lever with a toggle design. Oftentimes, electronic controls make use of either radio frequencies or infrared powers. High scale stairlifts may, in some cases, actually feature self-diagnostic controls. These controls are beneficial in that when the components of the stairlift begin to deteriorate, the information could immediately and automatically be transmitted to the service provider. The service provider, in turn, would be able to arrange a service visit in order to ensure optimal performance of the stairlift without at all inconveniencing the user. Despite the fact that the stairlift is primarily employed by those with mobility concerns, there are additional uses for such mechanisms. These devices can also be used to assist in the carrying of groceries, luggage and other arduous items from floor to floor of a structure.
