Multi Purpose Insert Bridge (
MPI
)
Bridge Setups
As Cantilever Bridge
1-
Using a rough terrain forklift or a crane, lift the fi rst multi purpose insert bridge (
MPI
)
(fi g. 3.30) and align the top and bottom parts with the motorized unit. Make sure that
the dedicated wall side (fi g. 3.19, p. 48) is turned
towards
the face of the work.
2-
Assemble the top part of the
MPI
bridge to the motorized unit using four 1" x 2" long
(
GR5
) bolt and nut assemblies through the outer assembly sockets (fi g. 3.19,
p.
48).
Do not tighten the bolt and nut assemblies yet
.
3-
Using four sets of bridge link plates and pins (
TYPE 1
link plates, fi g. 3.29), attach the
bottom part of the bridge to the motorized unit (fi g. 3.31).
4-
Tighten the nut and bolt assemblies
(4) at the top of the bridge to 100 lb-ft (136 N-m)
of
torque.
5-
Lift and align the top and bottom parts of the second
MPI
bridge with the fi rst
MPI
bridge installed. Assemble the top part of the bridges as described in step 2.

6-
Using four sets of bridge link plates and pins (
TYPE 2
link plates, fi g. 3.29), attach the
bottom part of the bridge to the other bridge installed. It is important to note that
TYPE 2
link plates must be used to attach the bottom part of each subsequent
MPI
bridge installed (fi g. 3.32).
Tighten all bolt assemblies
to 100 lb-ft (136 N-m) of
torque.
7-
Repeat steps 5 and 6 to continue installing as many
MPI
bridges as is required and
allowed. For more information on the types and number of bridges allowed in a
confi guration, refer to the
Load Capacities
section on p. 80.
8-
Once the installation is complete, install the appropriate guardrails. Refer to p. 91 of
the
Accessories
section for more information on the installation and use of guardrails.
As Lateral Cantilever Bridge
1-
Using a rough terrain forklift or a crane, lift the fi rst multi purpose insert bridge (
MPI
)
and align the top and bottom parts with the motorized unit, as shown in fi g. 3.35, p. 51. Make
sure that the connector angles (fi g. 3.19, p. 48) are turned
towards
the motorized
unit.
