The Straight Stair Lifts
All of the straight stair lifts made by Bruno can operate up to a maximum incline of 45 degrees and to a minimum stair case width of 32". Other companies can offer better specifications; the Stannah 120 stair lift can handle an incline of 52 degrees and the Acorn Superglide Perch stair lift can be fitted on narrower stairs. However, most domestic staircases can be fitted with a Bruno stair lift.
Bruno also makes a curved stair lift called the Electra-Ride III Curved Rail. Again what's impressive about this stair lift is that it can carry up to 350 lbs. The Stannah curved stair lift carries less than 300 lbs.
All of Bruno's stair lifts are powered by DC 24 volt rechargeable batteries. Just about all modern stair lifts now use batteries rather than mains power. There are many advantages to using batteries; they're safe with no possibility of electrocution; they provide smoother starts and stops; and you can still use the stair lift during power outages. What is particularly impressive about Bruno stair chair lifts is the length of their battery life. The company claims that the battery will last an amazing 3-4 days or 15 trips up and down the stairs. The battery itself is built to last 3-5 years and replacements can easily be bought from your local hardware store.
