INNER PONTON AND OUTER PONTON SEPARATION (Contd)
CONNECTING OUTER PONTONS TO INNER PONTONS
WARNING
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 ponton. Failure to comply may
result in damage to equipment or injury to personnel.
NOTE
Connecting of left and right outer pontons is performed the same
way. Left side is shown.
1.
Secure stabilizer bracket (8) in vertical position.
NOTE
IRB hoisting gear must be adjusted so that outer ponton will hang
level during connection.
2.
Attach IRB hoisting gear and lifting device to load receiving pins on outer ponton (1).
WARNING
Ensure tag lines are held tight to prevent outer ponton from
swinging. Failure to comply may result in injury to personnel or
damage to equipment.
3.
Using lifting device, raise and position outer ponton (1) next to inner ponton (9).
NOTE
Use adhesive to hold spacers in place.
4.
Position spacers (2) on outer ponton (1) and spacers (7) on hinge bracket (6).
5.
Position outer ponton (1), and install hinge bracket (6) on outer ponton (1) with four washers (5)
and screws (4). Do not tighten screws (4).
NOTE
Apply a light coat of grease to pins at installation.
6.
Align outer ponton (1), and install pin (16) on outer ponton (1) and stabilizer bracket (15).
7.
Lower outer ponton (1) to fully open position and level with dunnage until pin (16) can be easily
removed and installed.
8.
Remove pin (16) and install two spacer plates (14) and pin (16) on outer ponton (1) and stabilizer
bracket (15).
9.
Align pin (16) and install screw (18) on outer ponton (1) and pin (16).
10.
Install screw (17) on end of pin (16).
11.
Turn stopscrew (3) counterclockwise until spacers (7) contact edge of recess on outer ponton (1),
then tighten four screws (4).
12.
If jamnuts (22) and nut (23) on turnbuckle (20) were moved, adjust length of turnbuckle (20) to
12.835 in. (326 mm) by measuring from center-to-center from holes in clevises (see WP 0020 00-6)
and turning nut (23). Tighten two jamnuts (22).
13.
Using lifting device, lift outer ponton (1) and swing and lower outer ponton (1) down until
turnbuckle (20) can be installed on torsion bar lever (27) and stabilizer bracket (26) with two pins
(24), washers, (25), and screws (21). Lower outer ponton (1) down until resting on inner ponton (9).
14.
Close foldlock (19) on outer ponton (1).
15.
Connect connecting link (10) to stabilizer bracket (8) with pin (11), washer (12), and screw (13).
