5. The Columns and Cross Tubes will now be in position
and spaced properly for the runways.
6. Install the column TOP CAPS using the M16 X 2 Hex
Bolts, nuts & washers. Install the nut on each Safety
Ladder until 1/2” of threads are exposed and the Ladder
is raised at least 1/2” off of the base of the Column.
NOTE: Raise the Ladder at least 1/2” off of the base of
the column or damage to the lift will occur. Be sure to
position the Cable hole INWARD. (See Fig. 3.6 - 3.7)
STEP 4
(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.
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 important that the SLACK SAFETY
LOCK IS CLEARED. The Slack Safety Lock must never
rest on the Safety Ladder. (See Fig. 4.1 -4.3)
3. The Columns and Cross Tubes will now be in position
and spaced properly for the Runways. Be very careful not
to disturb the Columns and Cross Tubes at this time as
they may tip over causing personal injury or harm.
