Bridge Installation Support Brackets
Step A:
Under the bridge to be installed, slide hitch pins in the designated holes on both sides
of the bridge and secure them with linch pins.
Step B:
Using other hitch pin and linch pin assemblies, attach the bridge installation support
brackets to the bridge already bolted to the motorized unit or the bridge.
Step C:
Lift the bridge to be installed and lower it down so that the hitch pins are completely
supported by the bridge installation support brackets. Assemble the bridges using the
appropriate bolts and nuts. Remove the brackets when the bridges are bolted together.

The use of the bridge installation
support brackets requires that at
least two persons handle the bridge
installation maneuvers. Bridge
installation support brackets are
used whenever a bridge must be
lifted by hand and no appropriate
lifting device is available.
Access Stairs
When the motorized unit is at base level, workers may use the optional access stairs to
reach the platform. The access stairs can be installed on a bridge in the setup.
1-
Install the door guardrail by sliding the guardrail legs in the guardrail pockets on the
bridge. Secure the door guardrail with two toggle pins.
2-
Slide the top part of the stairs into the top outrigger pockets (fi g. 8.13).
3-
Unfold the stair brace.
4-
Secure the stair brace to the bottom truss of the bridge (fi g. 8.12) with two toggle pins.
5-
Secure the top part in place by sliding in two toggle pins and tightening each outrigger
pocket bolt.
6-
Install the handrails (2) and secure in place and tighten the bolts.
7-
If the height between the bearing surface and the fi rst step is greater than what is
allowed by local regulations, it is mandatory to install one or more optional extension
stairs (fi g. 8.12). A
maximum
of three (3) extension stairs is allowed per access stairs

10' (3 m) bridge nor the fi rst bridge to be bolted directly on the motorized unit
.
