3-
Mark the position of jacks. The distance between the front and rear jacks is 91" (2,3 m),
while the distance between the left and right jacks is 74" (1,9 m) (fi g. 7.99, p. 112).
4-
Using the supplied X-braces, assemble the two frames of the fi rst base support
structure together. Verify the squareness of the assembly and make corrections, if
necessary.
5-
Loosen the retaining bolt on each leg of the frames (fi g. 7.98, p. 112) to release the
screw
jacks.
6-
Repeat steps 3 to 5 for the second support structure.
7-
Using a rough terrain forklift or a crane, lift and position the fi rst adapter base frame on top
of one support assembly. Refer to the table in fi g. 7.104 to determine the distance
between the mounting fl ange on the adapter base and the front edge of the support
assembly. The adapter base frame will be moved back by 10" to 12" (25 cm to 30 cm)
from the front edge of the support assembly for each plank required by the confi guration
(as shown in fi g. 7.104). If necessary, install the support assembly further back from
the face of the wall for larger planking confi gurations (see step 1 and fi g. 7.104). Use
the
Outrigger Selection
table on p. 95 as a guide for planking confi gurations.
8-
Secure the adapter base to the support assembly by tightening each girder clamp
assembly
(fi g. 7.102, p. 112) to a torque of 108 lb-ft (147 N-m).
9-
Verify the level of the adapter base and the support assembly. Adjust the level using the
screw jacks on the support assembly or by adding cribbing.
10-
Repeat steps 7 through 9 for the second adapter base.
WARNING
Once the unit is installed on the adapter base, it is
mandatory
to install the
fi rst two tie levels on both masts
before proceeding with the installation.
