Securing the Ladders
Because it is much easier to secure the Ladders at the bottom of each Post after the Crosstubes
have been raised, that procedure is described here.
The following procedure assumes that the Ladders are in place and secured at the top. If this is
not
the case, return to Installing the Ladders and Top Cap .
To secure the Ladders :
1. Locate the required 4 Hex Head Bolts, 8 Flat Washers, 4 Spacers, and 4 Nyloc Nuts.
2. Secure the bottom of the Ladders as shown in the drawing below, making sure to orient the
Spacer between the Ladder and the back of the Post.
Drawing shows the
connections to make to the
bottom of the Post.
Not all components are
shown. Some components
stripped away for clarity.
3. Perform the same procedure to secure the other 3 Ladders on the Lift.
4. Make sure the Primary Safety Locks are engaged.
⚠
WARNING Do not continue with the installation until you have visually confirmed that all four
Primary Safety Locks are engaged. If they are not engaged, the Runways could
move or fall, possibly causing injury (even death) or product damage.
5. If you haven’t already done so, stand up each Post. Have at least two people work together to
stand up a Post.
⚠
CAUTION Use caution when walking around the Posts; they are not anchored down at this
point, so it is possible to knock them over, which could cause injury.
6. Use a Transit Level to estimate the Shim requirements: use a target to find the difference in height
between the Posts. The difference is the estimated amount of Shim thickness you will need.
Do not use Shims and/or Anchor Bolts to shim more than 1/2 an inch.
Do not anchor the Posts at this point
