Swivel bridge installations require the use of special guardrails, included with each shipped
swivel bridge. The installation of guardrails on a swivel bridge will depend on the angle of
the confi guration. Guardrails used in the confi guration will also be diff erent whether the
swivel bridge is used in a
cantilever
or a
bearing bridge
installation.
Since not all swivel bridge guardrails may be necessary for a given confi guration, refer to
specifi c instructions for each confi guration for the assembly of the appropriate guardrails.
It is important to note that swivel bridge guardrails must not be used to tie a lifeline
.
Installation of swivel bridge guardrails
Angle adjustment (cont’d)
2-
Position the swivel bridge installation at the desired angle by turning the adjustment
nut. Refer to the angle sticker located under the trap door on the bridge deck or on the
pivot pin at the bottom of the bridge (fi g. 3.24, p. 56) to make sure the installation
is at an appropriate angle. A swivel bridge confi guration must only be installed at an
angle between 0 and 45 degrees or at exactly 90 degrees. For any confi guration
between 45 and 90 degrees (red areas on the angle confi guration sticker), contact
the distributor/service center.
