INSTALLATION CRITERIA FOR 4Safe BARRIER H4b W6 A (3n31622)
In concomitanza con le norme generali di montaggio specificate nel capitolo introduttivo vanno osservate le seguenti
linee guida per l’installazione della barriera 3n31622.
Preliminary operations
Where installation is to be carried out in traffic, all necessary road signs must be set up in order to direct traffic and
protect workers from vehicles, in accordance with safety regulations.
The parts making up the road barrier can be unloaded from the transport vehicles by means of a crane fitted to the
vehicle, or forklift truck, in accordance with current safety regulations.
Workers must be supplied with all required equipment, including safety shoes, gloves and goggles and - where
necessary - helmets, safety harnesses and all else specifically needed for the site and required by current safety
regulations.
Installation sequence
The assembly diagram provides instructions for correct barrier installation. Fully and completely follow these
instructions.
Main steps:
1. Trace out a full line of reference on the ground, which will serve to align mounts, beams, and all other
longitudinal parts.
2. Place the beams (2) along the traced line taking into account the direction of traffic.
3. Prepare the anchor rod holes 1500 mm apart and install the M18 TSM B 16x190 mm (8) anchoring screws
as follows:
Drill a hole with an electric drill and 16 mm bit to the recommended 130 mm depth
Remove dirt from the hole using compressed air.
Brush the hole interior using a 18 mm diameter brush.
rimuovere ancora con aria compressa la polvere dall’interno del foro.
Starting from the bottom, fill the hole with the chemical anchoring component.
Insert the anchor rod in the hole and screw it in with an impact screwdriver, with minimum
40 Nm torque.
When the screw reaches the bottom of the hole, a small part of the previously injected
chemical anchoring component should seep out.
In case the chemical component does not seep out, this means that an insufficient quantity was
injected. In this case, unscrew the anchor rod and inject more of the chemical anchoring
component.
Screw in the anchor rod with the impact screwdriver with minimum 40 Nm torque.
4. The uprights HEA120 h=1350 mm (1) are vertically lifted and fastened to the base at the anchoring rods,
screwing the lock nut onto the anchoring rod.
5. Apply the upper barrier (6) on the upright using the clamps(4). At the joint between the two subsequent
barrier elements, connect the plates between them using 8 bolts: 6 M16x45 mm bolts and 2 M16x65 mm
bolts, which are also used to connect the plates to the corresponding upright.
6. Apply the second lower barrier (6) on the same side of the upright following the instructions above and
keeping joints between barriers at the same pole.
7. Assemble the spacers (3) on the two sides of the upright using the M16x45 mm bolts;
8. Assemble the beams (2) that have been laid on the ground, attaching them to the spacers (3) and
themselves, by means of the bolts supplied and the set plates.
9. Use the calibrated pneumatic screwdrivers to fasten all nuts and bolts into place, checking levels and
alignments.
10. Installation must always take place under the surveillance of a specialist technician, and in full
compliance with the final drawing and current safety regulations.
