To install the Crosstubes:
1. Orient the Crosstubes in their required locations:
• The Crosstube with two Large Windows must be on the Pull Box end of the Powerside
Runway with both Windows facing the inside of the Lift.
• The Crosstube with two Small Windows must be located next to the Power Post with both
Windows facing the inside of the Lift.
Both Windows must be on the ends of the Powerside Runway and facing the inside of the Lift.
2. Lean over the
two Posts at one end of the Lift (some people put them on Sawhorses, some
people let them lay on the ground), slide the Crosstube into place, then stand the Posts back up
again (make sure to put them back into their correct locations).
or
Using a Forklift or Shop Crane, raise a Crosstube above the top of the two Posts that it goes
between, then slide the Crosstube down into place.
3. Perform Step 2 for the second Crosstube.
About Slide Blocks
The black Slide Blocks in the corners of the ends of the Crosstubes come installed from the factory. If
they fall off or do not come installed, put them into place so that each pair creates a Slot into which the
Ladder for each Post will be installed later in the installation procedure.
The following drawing is a top view of how two Slide Blocks get put into position on the end of a
Crosstube.
The following drawing is a top view that shows the Slot created by the two Slide Blocks when they are
installed. There are two Slots per Crosstube Gusset, one at the top and one at the bottom. The Ladder
must go through both Slots.
Important: It is easy to see the top Slot created by the Slide Blocks. It is difficult to see the bottom
Slot, but it is
required that the Ladder go through both Slots.
