3.9.2.4
Attach tag lines by looping the rope through the end beam pinhole and hooking the loop
through the karabiner to secure it in place Figure 3. 29 (B).
Sling Extraction Tool
3.9.3.1
The webbing slings fitted to the ramp and bridge modules are susceptible to submersion
when the bridging modules are stored on their flatracks. Under normal temperatures, this
is not a problem, but when freezing weather is expected or experienced they can freeze.
If this happens it can be very difficult to extract/insert the webbing lifting slings.
3.9.3.2
To aid in extraction/insertion a special tool is supplied and is illustrated in Figure 3. 30.

3.9.3.3
To extract the webbing lifting slings from the bridge/ramp module girder section insert the
small hooked end of the tool into the hole in the track way decking of the bridge/ramp
module. Hook the loop of the webbing sling and gently pull the sling through the hole.
NOTE
Should the strap be frozen in pooled water it may be necessary to break the ice first.
3.9.3.4
To insert the sling into the bridge/ramp module girder section push as much as possible of
the webbing lifting sling back through the track way decking and use the extraction tool to
push the remainder inside the girder section.
Slinging and Opening Ramp Modules
3.9.4.1
Open the bridge module lifter to its widest position (OPENING) and secure the arms with
the locking shootbolts.
3.9.4.2
Connect the bridge module lifter to the single leg sling and the sling to the hook on the
crane. Ensure that the safety clip on the crane hook is correctly positioned so that the
sling cannot become disconnected from the crane. Also, ensure that the safety clip on the
hook at the end of the single leg sling is similarly correctly positioned so that the bridge
module lifter will not become accidentally disconnected.
3.9.4.3
Connect the hooks on each leg of the bridge module lifter to the opening lifting sling fitted
to the beams of the ramp module.
