The rail
Figure 2-3: Minimum distance from the stair threads
In most cases the rail starts vertically on the floor at the bottom. Here the minimum distance from the front of the
stair tread to the front of the rail is 175 mm.
The standard version is equipped with a horizontal section of rail on the top landing. The distance between the front
of the last stair tread and the end of the rail is a minimum of 200 mm.
Ends
The horizontal end of the rail is fitted standard with a cone-shaped rail cover that makes it easier to mount the drive
unit on the rail.
A black flat rail cover (Flow1) is also supplied for situations in which the grey cone-shaped rail cover is not a good
match to the colour of the rail. In this case the cone-shaped rail cover is only used to mount the drive unit, after
which the black flat rail cover can be fitted.

Emergency end stop
With a horizontal rail runout, an emergency stop is fitted on the underside of the rack. A counter ensures that the lift
position is retained. To prevent the stairlift moving past a stopping place and running off the rail as a result of
technical problems, a mechanical emergency stop is fitted. This end stop consists of a small strip that is fitted in a
cut-out in the tooth rack.
The emergency stop activates the final limit switch, which stops the drive motor drive and activates the electric
brake.
