What We Offer

The SL600 HD lift is rated for 600 pounds, with an extra-wide seat and a high backrest.
Heavy-Duty Features
The SL600 HD provides a higher-capacity option for people who need more room and support while traveling between floors. It is designed for straight staircases with enough space for the wider lift.

Questions
Standard home stair lifts are commonly rated around 300 pounds, while heavy-duty models go up to about 600. The Harmar SL600 stair lift carries up to 350 pounds, so a rider above that weight, or one who needs more room in the seat, is better suited to the SL600 HD. If an existing standard lift no longer suits the rider, stair lift removal takes it out.
Yes, a little. The SL600 HD travels at 14 feet per minute, compared with 20 feet per minute for the standard SL600. The SL600 HD is also rated for indoor use only.
The model, the options chosen, and the staircase itself all shape the price. Batteries also need replacing every so often, so plan for that cost over the life of the lift.
It depends on the width. The SL600 HD sticks out 16.5 inches from the wall when folded, compared with 10.5 inches for the SL600, so it needs more room. For the seat to swivel at the top, Harmar stair lifts require about 27.5 inches of stair width. If your stairs are tight and the rider is under 350 pounds, the SL600 may suit them better.
A straight heavy-duty lift is generally quick to put in, because nothing is custom-built. Timing depends on your staircase, and a lift you already own can move with you to a new home through our stair lift reinstallation service.
