Bridges
Forward Extension Bridge
(optional)
1-
Remove the plank stop pins from two outriggers and slide the outriggers in the bottom
outrigger pockets of a bridge assembly already installed, leaving about 6" (15 cm)
protruding from the bridge. Do not tighten the bolts.
2-
Align the bridge that will be used as an extension with the installed bridge and slide the
protruding ends of the two outriggers from the bridge assembly in the bottom outrigger
pockets of the forward extension. Insert a plank stop pin in each outrigger.
3-
Install the fi rst two forward extension plate assemblies at the
TOP
of each of the two
vertical tubes at each end of the bridge assembly (fi g. 3.15). If using only previous
generation bridges, install the third extension plate assembly on the middle vertical
tube of the bridge, secure the bolt assemblies and proceed to step 5.
4-
If using at least one new generation bridge in the installation, install the third forward
extension plate assembly at the
TOP
in the middle of the bridge structure by positioning
the plates so the holes align with the holes on the plate in the middle of the bridge
structure (fi g. 3.18). Secure with bolt assemblies.
5-
Tighten all the bolts on the outrigger pockets and on the extension plates to a torque
of 30 lb-ft (41 N-m).

Installation
The extension bridge (used on the front of a motorized unit setup) is assembled using
a regular bridge, two outriggers and three forward extension plate assemblies. Refer to
p. 99 of the
Load Capacities
section for the load capacities and the appropriate positioning
of a forward extension bridge in a setup.
