4. Pull truss cable over truss support brackets, around upper truss anchor and
back over truss support brackets to lower truss anchor, holding it loosely in
place with one 5/16” cable clamp at upper truss anchor, and two 5/16” cable
clamps at each truss support bracket.
Important: Do not tighten cable clamps at this time.
5. The upper end of
augers equipped with
truss cables should
have an upward bow
before being placed
on the transport
undercarriage (auger
tube will straighten
when fully
assembled). Place
supports under the
discharge end until
upward bow is
correct.
• The upward bow
should be about 2”
(5.08 cm) on the
46’ and 51’, 3” (7.62 cm) on the 56’ and 61’, and 5” (12.7 cm) on the 71’
auger.
6. Place other eyebolt onto lower truss anchor and thread on nut a short way.
7. Insert other end of truss cable through this eyebolt. Pull out all slack and
secure with a cable clamp.
8. Tighten eyebolts to take remaining slack out of truss cable and to maintain
the appropriate upward bow. After tension is adjusted, tighten cable clamps
on truss support brackets and upper truss anchor. Check for proper side
alignment.
Important: Once auger is fully assembled, adjust truss cables on all units (because of initial
stretching). Cables may also require adjustment for side alignment.
