The Pinnacle Heavy Duty stair lift features an industry leading 600 lb weight capacity. It is based off the Pinnacle SL600 model, but features upgraded wheels, armrests, footrest, and swiveling seat. The seat is 25 inches wide between the armrests, leaving plenty of space to sit down and stand up.

Although the Pinnacle Heavy Duty stair lift is built for strength, it does not fall short on features. It still includes all of the same, top of the line safety features from Harmar and comes standard with a longer seat belt. The Pinnacle Heavy Duty stair lift also features a patented helical worm gear drive system. The gear system requires virtually no maintenance, as no messy greases or lubricants are necessary. No grease means that the stair lift rail attracts less dirt, dust, and pet hair, making the stairlift easier to keep clean. 

For added piece of mind, the Heavy Duty model carries a 3 year warranty on all parts, while we provide a one year warranty on labor.

Additional Notes

The Pinnacle is the only stairlift on the market incorporating a helical worm gear drive. This drive system is a proven system. The helical worm drive also gives the Harmar Pinnacle extended battery life. Due to the improved efficiency of a helical worm gear drive over a standard rack and pinon drive, you can get an industry leading 40 trips or more on battery power during a power outage.
