Anchor NAVI-TRAC LITE 20 WIDE - Manual (Page 18)

UNITS WITH 2 GABLED ENDS - - FRAME SAFETY
A structure with (2) Gabled Ends lacks the initial stability nor-
mally provided by the hip end frame during installation of the
first middle beams. To compensate for this, we have provided
Installation Safety Guys to stabilize the first standing beam until
additional beams are connected to it. (see fig. 49)
Notice that the first beam raised is actually the second beam of
the frame system (fig. 49). In this way, the first beam raised
can be safely guyed to the base plates of the adjacent beams
on each side.
Next, the first beam of the layout is raised and joined to the
second (fig. 50). When X-cabling has been installed in this
first bay, the structure is secure for standing the remaining
beams in the same way previously shown for standing middle
beams (fig. 51).
Caution: While standing beams, be sure to “foot” the base-
plate so that the beam does not slide out from under the work-
ers pushing it up.
After the first bay has been X-cabled, the installation safety
guys can be removed.
Gabled Ends are installed in the same way as the Hip-Gabled
units described above.
As before, be sure to guy out the frame before installing fabric.
Note: When the overall length of the unit exceeds 60 ft, an
additional bay must be X-cabled for stability (see fig. 52). At
no place in the length of the unit should there be more
than 60 consecutive feet of non-X-cabled frame.
