Mounting ladder rails under the ceiling
5. Mount ladder rails under the ceiling with 2 M10 truss-head bolts each
on the head plates.
– 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!
To connect additional ladder rails to the mounted ladder rails, see “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 70 mm between the end of the ladder rail and the floor.
