Assembly using hammerhead screw
Fig. 20: Assembly using hammerhead screw
During assembly of the fall protection rail and
other system components using hammerhead
screws, please observe the following procedure:
1.
►
Insert the hammerhead screw in the
opening in the rail profile.
2.
►
Turn the hammerhead screw by 90° in
the fall protection rail profile and posi-
tion the square neck of the hammer-
head screw in the opening in the rail
profile.
⇨
Only this way is a secure connec-
tion guaranteed.
3.
►
Check that the slot mark on the ham-
merhead screw [X] is in a horizontal
position.
4.
►
Tighten both nuts.
⇨
The minimum tightening torque for
the nuts during initial assembly to-
tals 27 Nm.
IMPORTANT!
The fall protection rail (material: alumin-
ium) may only deviate from the vertical
by -3° – +15° once installed.
During the annual fall protection rail in-
spection, ensure that all screw connec-
tions exhibit a tight fit.
Check that the slot mark on the hammer-
head screw [X] is in a horizontal position.
If a nut has become loose, retighten it
with a minimum tightening torque of
27 Nm.
