Many households have decks or patio locations that are accessible by a stair case situated outdoors. For those with conditions that affect their mobility, an outdoor stair case can present a daunting challenge. Luckily, there are several choices available for those that need to have an outdoor stair lift.

All stair lifts are composed of four fundamental components the track, the drive train, the chassis, and the seat. The drive train is located inside of the chassis and consists of the gears or pulleys that propel the chassis and seat up and down the track. The drive train can be either rack and pinion or cable driven. Rack and pinion systems use gears and a toothed rail along the track. Cable driven systems use a high strength aluminum cable that is wound about a pulley inside of the chassis.

The stair lift track is the portion that is truly mounted to the stairs and structural steel supports the weight of the chassis, seat, and rider. Depending on the kind of stair lift, the track also houses the toothed gears for rack and pinion lifts and the high strength cable for the cable driven lifts.

The chassis contains the electric motor that moves the lift up the rail. The seat is mounted on top of the chassis enclosure and typically folds up whilst not in use.

There are a handful of elements to consider when installing a stair lift on an existing stair case. Specific attention need to be paid to the material that the methods are constructed from. Concrete steps will call for various types of fasteners than wooden actions. Also, the length of the stair case must be measured in order to obtain an accurate price quote from a distributor. Every stair lift track is custom cut to the home owners specifications and the length will have an effect on the final cost of the stair lift.

For a straight stair case, a stair lift is a secure and economical resolution but for outdoor use the chassis and track of the stair lift must be sealed to safeguard against the components. Also, the seat need to be of a marine grade vinyl or similar material to withstand sunlight and moisture. Most outdoor models also include a cover for the seat so that it is protected when not in use.
