The Harmar Helix curved stairlift parked at bottom landing with a 90-degree turn.
Harmar Helix Curved Stair Lift Manual. The most common problem we see on the Helix lift is over travel at the bottom or top landings. This occurs when the normal limit moves causing the lift to hit the final limit. When this happens you’ll need to call for service and have the limits reset and the lift checked. Other than normal maintenance this lift typically only needs annual service checks.
