1- Make sure that the adjustment rod is installed on the appropriate side of the bridge to
achieve the desired confi guration. If required, remove the bolt assemblies at both ends
of the adjustment rod and reinstall it on the other side of the bridge (fi g. 3.26, p. 56).
2- Part “B” of the swivel bridge guardrail assembly is not required for 90° back bearing
confi gurations. Separate all three parts (“A”, “B” and “C”) of the swivel bridge guardrail
assembly, if necessary.
3- Assemble part “A” and “C” of the swivel bridge guardrail assembly.
4- Align the plates of the guardrail adapter (fi g. 3.43, p. 60) with the front of the guardrail
on the link bridge of the unit and secure in place with bolts.
5- Align the hinge tubes on the swivel bridge guardrail assembly with the hinge tubes on
the adapter on the link bridge guardrail and secure in place with guardrail assembly pins.
6- Install the gap fi ller (fi g. 3.51) to fi ll the gap on the deck. Secure in place with gravity lock pin.
7- Install a 60" (1,5 m) regular guardrail on the bridge attached to the swivel bridge.
8- Overlap part “C” of the swivel bridge guardrail assembly on the 60" (1,5 m) guardrail and
secure in place by tightening the bolt on the sliding bracket (fi g. 3.51).
9- Make sure all the necessary guardrails are in place and secure (see the Accessories
section on p. 108 for more information about guardrails). In all cases where workers
are exposed to fall hazards greater than specifi ed by local regulations, the installation
of guardrails or face guardrail supports is mandatory.
