Stair Lift Specs

Stair lift Specs.

Of the three common alternatives for providing access between floors (residential elevators, stair lifts or stair lifts, and platform lifts) the stair lift is by far the least expensive option.

Straight stair lifts range in price from 2.5k - 4k, and between 4k - 15k for retrofitted curved models. As the complexity of the stair design increases so will the installation costs. Curved rail lifts require a highly detailed on-site survey prior to order and can take up to 3 months to be built and delivered.

Drive Type - There are 4 types of Stair lift drives that are available for consumer purchase.

• Cable - Most cable drive systems use a strong steel cable, the kind used in elevators, to advance the passenger. Some have said that cable drive stair lifts don't have smooth starts and stops but it really depends on the model.
• Chain - Usually only used for heavy duty models. Can be loud at times.
• Screw - The lifting mechanism used is a screw driven actuator, which is powered by a rechargeable battery.
• Rack & Pinion - Users ride is smooth and controlled. Speed can be set by installer. Rack and pinion (meaning gear and teeth). The systems must be cleaned and lubricated regularly to prevent damage to the components. Gear teeth can be hazardous, especially to children, but most models have hidden gears.

Many manufacturers have discontinued their cable, chain, and screw drive systems, with the exception of their heavy duty models. Rack & pinion are the one's mostly used today. However, Drum and Cable systems are amazing too!

Rail / Track - The track used with a stair lift is secured to the stairs. Steel and aluminum are the primary metals used in manufacturing the tracks. Steel is often used for custom engineered applications, where as Aluminum is typically found in straight applications because of its lighter weight and interchangeability.

Power - Most Stair lifts today are powered by batteries or a domestic mains supply. Either AC (mains supply) or DC powered (battery). AC powered units use a trailing mains cable that is said to be less reliable than the DC battery powered units. Furthermore, the trailing cable needs to be reeled out and reeled back in, each and every time the stair lift travels up and down the stairway. AC powered units can be recharged anywhere along the track, whereas DC powered units can only be recharged at the base stations at the top and bottom of the stairs. There are several states where they prohibit the installation of AC powered equipment unless you are a fully qualified electrician.

There are two types of Station Charging: 

• Static Charging - consists of permanent charging stations positioned at each end of the rail.
• Flexible Charging - allows the charging stations to be moved anywhere on the rail.

Swivel Seat - To safely access the upper landing of the stairs, one must swivel the stair lift seat onto the landing. A lock release lever allows the seat to turn. Some seats have a single or dual release arms. 

There are two types of swivel seats: 

• 90° Swivel Seat - This type of swivel seat is mounted on the upstairs side of the chassis and fold in one direction.
• 180° Swivel Seat - This model folds in both directions.

Diagnostics - Many newer stair lifts offer a self diagnostic system that can help diagnose problems with your lift and decrease maintenance costs.

Accessories - There are a number of accessories available to complement your Stair Lift. These accessories are great for individuals with additional mobility difficulties and/or more complex stair configurations.

• Sit and Stand Frame - Allows the passenger to choose between sitting and standing.
• Seatbelts - Great safety feature with offered in either belt or shoulder strap.
• Hinged Rail - Allows the railing to be moved from the bottom of the stairs.
• Bridging Platform - Used for curved staircases at the top of the landing.
• Power Folding Footrest - For individuals that have a hard time bending down.
• Power Swivel Seat - Automatically turns the seat for effortless entry and exit.

Installation - Many stair lifts are manufactured so they can be easily installed. Some individuals decide to install it themselves while others prefer to have them installed by the manufacturer. Most stair lift manufacturers will have measurement and installation guides readily available on their websites and are very helpful if you have any questions.
