INNER PONTON AND OUTER PONTON SEPARATION (Contd)
SEPARATING OUTER PONTONS FROM INNER PONTONS
All personnel must stand clear during lifting operations. Ensure
ponton foldlocks and travel latch are in good mechanical condition
and securely locked prior to lifting bay. Failure to comply may
result in damage to equipment or injury to personnel.
Separation of left and right outer pontons is performed the same
way. Right side is shown.
Open two foldlocks (3) from ends of outer ponton (2).
Ensure the two long chains of the IRB hoisting gear are connected
to the load receiving pins so pontons will hang level during
Attach lifting device and IRB hoisting gear to load receiving pins (1) of outer ponton (2). Lift and
swing outer ponton (2) to open position, and lower outer ponton (2) down on dunnage so that outer
ponton (2) is level with inner ponton (4).
Remove two screws (5) and washers (6) from bracket (8), spacer (7), and outer ponton (2).
Remove screw (15) from pin (11) and outer ponton (2).
Remove pin (11), two connecting links (12), and spacer plates (9) from stabilizer (10) and outer
Using lifting device, remove outer ponton (2) from inner ponton (4).
Remove spacer (7) from outer ponton (2) and remove pin (16) and bracket (8) from stabilizer (10).
Remove five screws (14) and brackets (13) from outer ponton (2) if necessary.
Perform step 9 if inner ponton(s) will be moved.
Attach lifting device and IRB hoisting gear hooks to two roadway pins to lift inner ponton (4)
