NEXT DAY Stairlift Installation | FREE Stairlift Quote | No Pressure to BUY
As we all know today stair lifts are designed to help handicapped or the old people who have a hard time managing the stairs even in their houses. Nowadays there are many manufacturers of stair lifts already like Acorn. There are many models of stair lifts to choose from Acorn stairlifts. Each has its own unique design and purpose to meet the particular need of a person with disability or an elderly.
There are three ways of providing access between floors for the handicapped or disabled; residential elevators, stair lifts and platform lifts. By far the most popular method of residential lift is the home chair stair lift.
The reasons why they are preferred by the majority is because of ease of installation and price. Residential elevators and platform lifts start at around 10k to 16k. The price of a home stair lift will depend on its type. A straight type will range in price from 2.5k - 4k, whereas a curved model is custom made and will cost anything between 5k to 20k. The complexity of the installation ultimately dictates the cost of installing a curved lift. The cost is impossible to know before the supplier carries out an onsite inspection.
There are four types of drive types. However, the vast majority of new stair lifts use the rack and pinion system.
Most cable drive systems use a strong steel cable - aircraft cable is the norm. The main disadvantage of this type of drive system is that the ride can be less than perfectly smooth. However, technology has moved on and those companies that still use this drive system say that the ride is as smooth as any other type. Summit and Ameriglide stair lifts both use this drive type.
Chain drive systems are used only for heavy duty models. They are loud and not really used in residential stair lifts.
The screw drive uses a lifting mechanism with a screw driven actuator. This is powered by a rechargeable battery. Again, this type is not used in home models.
The rack and pinion drive system is by far the most popular type for residential stair lifts. Rack and pinion systems - meaning gear and teeth - used to have to require regular cleaning and replacement of gear oil. However today’s home units have sealed drive systems that require no maintenance at all.
