a. Launching
- CONT
NOTE
The following launch and retrieval procedures are for use by maintenance personnel only
when testing newly assembled or repaired bridge assemblies. Refer to Operator’s Manual,
TM 5-5420-226-10 for operating instructions for the M48A5, or TM 5-5420-202-10 for
the M60.
b. Retrieval by Launcher.
The launcher can retrieve the bridge from either the near-shore end (the
end with the scissor cylinder) or the far-shore end.
Prior to retrieval, the following checks and preparations shall be performed:
•
Ensure the tongue pintles (1) line up with the holes in the launching diaphragm (2).
See illustration below.
•
Check the bridge for impacting (pushed into the terrain by user traffic). If impacted,
refer to paragraph
2-9e.
•
Ensure the quick-disconnects are cleared of any foreign matter.
•
Ensure no foreign matter has collected or lodged in the bridge structure.
•
Ensure uphill, downhill angle does not exceed 15% and side slope (cant) does not
exceed 8%. If either parameter is exceeded, contact engineering personnel for aid.
•
Ensure enough clearance exists for lifting and retraction.
•
Survey area for overhead power lines or other aerial obstacles.
•
Inspect the bridge for damage and make necessary repairs to allow retrieval. If
further repairs are required, perform those repairs prior to re-use. Perform repairs in
accordance with Chapter 3.
•
If bridge was crossed under “risk conditions” as defined in paragraph 1-8, bridge
shall be inspected by a bridge engineering officer prior to bridge being returned to a
serviceable condition.
