Mounting vertical ladders up to a max storey height of 3 5 m
Fig 9:
Mounting ladder rails under the ceiling
5. Mount ladder rails under the ceiling with 1 M10 truss-head bolt each
on the installation profiles.
– Mount the rails with the open sides facing each other.
– Place the bolts up to the limit in the slot, in order to prevent a verti-
cal movement of the vertical ladders.
Note!
At a storey height > 3 m, additional ladder rails must be connected with
the mounted ladder rails. See also “6.5 Mounting U support connectors”
on page 30.
Function loss through length expansion in the event of fire!
If there is a fire, the material of the vertical ladders expands.
Do not bolt the vertical ladder to the floor. Maintain a minimum distance
of 40 mm between the end of the ladder rail and the floor.
