WARNING
Cables under a strain may break. The bridge may shift and fall from its supports or a
component may fail causing the release of the towing cable. Any of these can cause injury
or death. Remain clear of the immediate area at all times when the AVLB is being towed.
Never place yourself in a position where a cable could strike you or where the bridge or a
component may hit you.
WARNING
The following recovery technique is extremely dangerous and should only be attempted
when time is not a factor and engineering support is available. The crane could tilt
resulting in the bridge being dropped into the gully, ravine, or stream. This, in turn, could
pull the towing vehicle or the crane to the edge and possibly into the gully, ravine, or
stream. Personnel operating the equipment will be in danger; therefore, ensure the best
operators available are used. CEASE OPERATIONS AT ANY TIME IF THERE IS
IMMINENT DANGER. In case of injury, seek medical aid.
WARNING
The bridge weighs 29,300 pounds. It may shift, slip or slide from the lowbed. When
removing tiedowns from the bridge, do so carefully. Maintain constant eye contact with the
bridge. Have one crew member watch the bridge for evidence of slipping, etc. If bridge
begins to slip, jump clear and to the opposite direction. Watch when removing chains.
Chains may be under tension and a backlash may occur. Chain binders are under tension.
Take care when releasing. The handle may come back fast, striking you on the arm or face.
Serious injury or death may occur. Know the results of your actions before you do them.
WARNING
Early operation of the holddown cylinder could result in the hands or fingers of the crew
member being severely injured or severed. Take all necessary precautions so as to preclude
injury. In case of injury, immediately take actions to control bleeding (refer to
FM -21-11, First Aid for Soldiers) and seek medical help.
WARNING
Working on, around, or under a suspended bridge is dangerous. Bridges may fall due to a
failure in the hydraulics or a mechanical break. Never turn your back on a suspended
bridge. Maintain an orderly work area and remain free of tangled cables, chains, etc.
