a. Launching - CONT
The following launch and retrieval procedures are for use by maintenance personnel only
when testing newly assembled or repaired bridge assemblies. Refer to Operator' Manual,
TM 5-5420-226-10 for operating instructions for the M48A5, or TM 5-5420-202-10 for
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,
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
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
