There is often a door or hallway at the bottom of the stairs that must remain accessible and free of fixed rail sections.
This is where the fully automatic swivel rail (special accessory) comes into its own. During the descent, the lower
guide rail section, including seat and passenger, is brought safely onto the floor in the hallway (see bottom pictures).

After the seat has been vacated, it travels back to its park position where it buts up flush with the bottom step.
The door area is free again.
Alternatively, an automatic folding rail can be installed. Here, the last section of rail is folded down to the floor
on a hinge.
Both versions are operated quite simply via the normal control units for the lift, so that the area of the swivel or
folding section is always within view of the user.
