ASSEMBLY - SINGLE STORY - 12 BAY (Restricted Site)
a.
General
Construction is made possible by using longer than normal launching nose, and counterweights. Since the
procedures are similar to those for a 12 bay bridge on a normal site (para. 5-3), only the steps that are different are given
in detail.
b.
Assembly
(1)
Carry out step a.(1) and (2), and step b.(1) thru (6) as detailed in paragraph 5-3.
(2)
Lift girders and move pedestals under rear of bay 2 to panel point 2p6.
(3)
Connect top panels of bay 3 to the top panels of bay 2, using a headless pin. This pin is required for
connection of launching nose cross girder post.
(4)
Lift girders and move pedestals under the rear of bay 3 to panel point 3p7. The building pedestals are
now in their final position and no further movement is required.
(5)
Fit launching nose cross girder post to headless pin at junction of bays 2 and 3.
(6)
Fit launching nose cross girder to posts at position 2.
(7)
Connect front and rear sections of light nose together.
(8)
Place front end of light nose section on nose roller and rear end on nose cross girder. Rear of nose
section should extend about 2 ft (0.61 m) behind cross girder.
