Section III. OPERATIONS UNDER USUAL CONDITIONS
2-3. ASSEMBLY AND PREPARATION FOR USE OF MLC 60.
The bridge may be received assembled, partially assembled, or in sections. Standby modes are addressed
In case complete assembly is required (bridge was received disassembled in 8 sections), one method is to
assemble the bridge by sections starting with the near-shore end. This means joining the near-shore ramp
sections together with the diaphragm, braces, and cylinder beam. Pin the near-shore center sections to
the completed end section, add the center section braces, install the scissor cylinder, and connect the
hydraulics. Then, the far-shore center sections will be pinned to the near-shore center sections at the
hinge. The far-shore center section braces will be installed. The far-shore end section is connected to the
far-shore center sections to complete the bridge. This method of assembly allows the lifting device to
work with small sections of bridge, and will be described in detail in paragraph 2-3c. Refer to paragraph
2-3d for assembly of a bridge
separated at center hinges.
a. Instructions for Using Sling. The sling, multiple leg is made up of two lengths of chain attached
on one end to one master link. On the opposite ends of the two chains are two hooks used to lift the
ramps and center sections of the bridge. Refer to page 2-12.
WARNING
Deck extrusions may be slippery You could fall. Take care when walking on deck. The
lifting sling could strike you. Maintain eye contact with lifting sling at all times.
(1)
Connect the master link (1) of the sling (2) to the lifting device being used.
(2)
Insert hook end (3) of sling through the deck extrusions (4) at the lifting brackets (5) located
on ramp section (6) or center section (7). Ensure hook is securely connected.
(3)
Repeat steps (1) and (2) for opposite length of chain and hook (3) at second lifting bracket
(5).
WARNING
Keep hands and feet clear of sections when attempting to position. The sections are heavy
and can cause injury to personnel if care is not used.
(4)
Using lifting device, lift ramp section (6) or center section (7) and place where needed.
(5)
