A through-floor home lift is a cabin that operates entirely within a self-supporting vertical rail structure. Unlike larger commercial lifts, it requires no messy pit to be dug beneath the ground floor and no separate machine room above the top floor.
How it Works: The Drive System
Most modern through-floor lifts operate using a sophisticated rail and winding drum system or a belt-driven mechanism.
Winding Drum: A motor drives steel cables or belts wrapped around a drum, hoisting the lift cabin up and down the vertical rails.
Power Source: The lift plugs into a standard domestic mains socket, usually requiring a dedicated circuit. Crucially, the lift runs on DC (battery) power, which is constantly charged from the mains. This is vital for safety, as it means the lift will always operate even in the event of a power cut.
The Aperture and Cabin
When the lift is called to a floor, a neat, self-closing aperture opens in the ceiling above (or the floor below). Once the user is inside, the cabin is fully enclosed for the short, quiet journey.
When the lift is parked at one level (e.g., the ground floor), the opening above is securely sealed by the platform’s floor panel, making it virtually invisible from the room above. This is the feature that gives it its space-saving edge over traditional lift designs.
