A stair lift is an essential part of any two story home where one of the patrons suffers from some form of mobility problem. The lift allows for easy access up and down the stairs, without the need to ask for help from those around you. Installing a stair lift is actually a fairly easy procedure if the owner understands the basic mechanics and measurements of the area. Once he or she has purchased the lift there are a few easy steps before it is in running order.The lower trackFirst, they must lower the track atop the stairs in question. If the measurements are correct, the track should fit nicely and attach to the brackets with a set of screws that are going to come with the lift. There is usually three brackets total: one on top of the stairs, one at bottom and one along the middle. When laying the tracks, make sure they are near the side facing the wall, not the rails. This is to prevent the user from blocking people walking up and down the stairs.The wiringNext, they must install the call box wiring through the track, from top to bottom. The wire should run beneath the bottom track and against the side with the wall. This will keep it out of everyone�s way and allow for easy accessibility by the user.The top trackThen, there is a top track that must sit firmly above the lower track. The base of the seat is going to attach perfectly between these two tracks. The top track screws perfectly into position, once again with the screws that came with the stair lift.Always make sure you have everything perfectly aligned against the wall. With the track too far from its recommended position it could trip people walking up or down the stairs. Powering the chainFinally, the user must run the chain through the center of the track and attach the power cable through its provided slot. This allows the chain to pull the seat along the track and thus allow for easy transport up and down the stairs.With the installation complete, there is a straight line from the bottom to the top. By keeping it out of the way of others, the track can easily carry a person with some form of mobile disability without running into any issues. It is a great fix for any house with more than one story or a large stair case.
