SECURING INTERIOR BAY AFTER LAUNCH (Contd)
Do not place fingers under transverse upper couplings
when closing them, or serious injury to personnel may
The transverse upper couplings and outer ponton locks
must be engaged prior to performing bridge or rafting
operations; the weight of a vehicle crossing will cause
the bay to fold up and may result in damage to
equipment or injury or death to personnel.
Use the roadway tool and crowbar to close the gap
between inner pontons when upper couplings cannot be
fully closed in receptacle blocks.
f. Close two transverse upper couplings (1) by folding each lever so that it
engages in receptacle block (2) of adjacent inner ponton.
g. Using T-wrench or round end of crowbar, engage two outer ponton locks (7)
at each end of both outer pontons. Visually check to see each lock/release
lever (3) is in catch plate (4).
h. Using T-wrench, turn lower lock-drive to ensure jackscrew (6) moves freely and
lower lock-drive pin (5) is fully retracted at each end of both inner pontons.
