5. If shimming is required, insert the Shims as necessary
under the Base Plate so that when the Anchor bolts are tight-
ened, the Columns will be plumb. (See Fig. 4.4)
6. After any necessary Shims are installed, tighten each
anchor nut three to five turns past finger tight. (See Fig. 4.5)
IMPORTANT - If Anchor Bolts do not hold when torqued to
required amount, concrete must be replaced. Saw cut and
remove 24” x 24” square area under each Column base then
re-pour with reinforced 2500 PSI concrete to a depth of six
inches minimum, keying new concrete under existing floor.
STEP 5
(Raising The Cross Tubes)
1. Before proceeding it will be necessary to first raise the
Cross Tubes off the ground to facilitate Cable routing and
final assembly.
ENSURE THAT THE FRONT POST UPPER AND LOWER
SLIDE BLOCKS ARE ORIENTED AS SHOWN IN FIGURE
3.3 ON PAGE 12. BEFORE PROCEEDING.
2. Manually raise the Cross Tubes until the primary Safety Locks
engage and rest on the lock position second down from the top
of the ladder or approximately 66” off the ground. It is impor-
tant that the SLACK SAFETY LOCK IS CLEARED. The Slack
Safety Lock must never rest on the Safety Ladder. (See Fig. 5.1)
3. The Columns and Cross Tubes will now be in position
and spaced properly for the Runways. (See Fig. 5.2)
IMPORTANT NOTE
It is important that the SLACK SAFETY LOCK IS CLEARED.
The slack safety lock must never rest on the safety ladder.
