Bearing Bridge Confi gurations
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- Lock the angle pivot between parts “A” and “B” of the swivel bridge guardrail assembly at
0° using the angle stopper (fi g. 3.45).
3- Align the plates of the guardrail adapter (fig. 3.43, p. 60) with the side of the
27" (69 cm) guardrail on the link bridge of the unit and secure in place with bolts.
4- Align the hinge tubes on the swivel bridge guardrail assembly with the hinge tubes on the
adapter on the 27" (69 cm) guardrail and secure in place with guardrail assembly pins
(fi g. 3.43, p. 60).
5- Install the twin mast adapter guardrail on the twin mast adapter.
6- Slide part “C” of the swivel bridge guardrail behind the assembly of parts “A” and “B”, as
shown in fi g. 3.45, and secure one end to the assembly of parts “A” and “B” using the
sliding bracket (fi g. 3.45).
7- Using guardrail assembly pins, secure the other end of part “C” of the swivel bridge guardrail
assembly to the twin mast adapter guardrail (fi g. 3.45).
8- 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.
