(1) Checks and Preparations. Prior to launching perform the following:
(a) Perform PMCS "Daily" and "Before" checks.
(b) Ensure all hydraulic bleed valves are closed.
(c) Ensure locking pins (located on outrigger) are fully extended.
(d) Remove any dirt or debris that could affect the hydraulic connections.
(e) Ensure no foreign matter has collected or lodged in the bridge structure.
(f) Survey the launching site. Ensure firm supportive base exists for launching.
(g) Ensure uphill, downhill angle does not exceed 15% and side slope (cant) does not
exceed 8%.
(h) Ensure enough clearance exists for lifting and extension. Far-shore placement site is
at same angle as near-shore launching site to avoid twisting and damage to the bridge.
(i) Avoid launching on stumps, large rocks, or other irregular shore (dips, etc.).
(j) Survey area for overhead power lines or other aerial obstacles.
(k) If launching in low or marshy areas, give consideration to other launching sites.
(1) Contact engineering personnel if fill or site improvement is required.
(2) Transporting and Positioning. The bridge is transported to the selected launching site in the
folded position on top of the transporting launcher. Perform the following procedures for launching
setup.
(a) Start the launcher.
