f. Recovery by Other Than a Launcher - CONT
(1) Tow the bridge to a distance that will allow access to both ends of the bridge for inspection
and repair. Perform any repairs needed IAW repair procedures found in Chapter 3. Load
the bridge on a launcher or transport IAW procedures in paragraph 2-10a( 1).
(2) Recovery With a Crane and Towing Vehicle.
WARNING
The following recovery technique is dangerous and should only be attempted when time is a
factor and engineering support is not available. The lifting device could tilt resulting in the
bridge being dropped into the gully, ravine, or stream. This could pull the towing vehicle or
the lifting device to the edge and possibly into the gully, ravine, or stream. Personnel
operating the equipment will be in danger. CEASE OPERATIONS IMMEDIATELY.
CAUTION
These procedures should be used as a last resort and only when the bridge has been
launched over a deep gully, stream, or river, and recovery by other means is not feasible.
Damage to the bridge could result.
(a) Inspect all cables, connectors, bolts, etc., for suitability for the task. Replace all
components that appear defective or show signs of wear, strain, or damage.
(b) Use 1/2 in. diameter wire rope or larger with no less than 23,000 pounds lifting capacity.
Place a cable around the launching diaphragm with protective timbers between the wire
rope and diaphragm as shown in paragraph 2-9f(1). Attach to the towing vehicle. Secure
all connections.
