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 M10 X 1.50 X
50 hex bolts, nuts & washers. Install the nut on each
safety ladder until 1/2” of threads are exposed and the lad-
der 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 )
3. The columns and cross bars will now be in position and
spaced properly for the runways. Be very careful not to dis-
turb the columns and cross tubes at this time as they may tip
over causing personal injury or harm. (See Fig. 4.2 )
