Before routing your Lifting Cables, you need to extend the Piston of the Hydraulic Cylinder.
To extend the Piston
:
1.
Remove the Shipping Plug from the Return Line Connector.
The Return Line Connector is on the Hydraulic Cylinder on the end away from the Pull Box.
2.
Attach an air pressure source to the Return Line Connector.
3.
Use the air pressure to extend the Hydraulic Cylinder’s Piston and Pull Box.
Do not exceed 50 PSI
.
If the Hydraulic Cylinder does not move, stop using air pressure; instead, use a pulling device (such
as a Come Along Tool) to extend the Piston and Pull Box. Be careful not to damage the Piston or
the Pull Box.
4.
Reinstall the Shipping Plug to the Return Line Connector.
The following procedure assumes you have nearby the four Lifting Cables and the Sheaves you
removed before you installed the Runways.
Use the drawings on the previous two pages in conjunction with this procedure.
To route Lifting Cables A and C
:
1.
Starting with Lifting Cable A
, move the entire thing to just under the Large Window it goes
through, near the bottom of Post A.
Check the label to make sure you have the correct Lifting Cable.
2.
Remove the Nut and Washer from the Threaded End, if not already done.
3.
Route the Threaded End of Lifting Cable A into its Large Window on the Crosstube, push it toward
the Power Post, then pull the Threaded End out of the Crosstube at the bottom of the Gusset.
You can access the Large Window on the Crosstube because the double Cable Sheave has been
removed. If it is not removed, it blocks access to the Large Window.
Not necessarily to scale. Not all components shown. Includes side view and top views.
4.
Route the Threaded End of Lifting Cable A
under
where the Gusset Sheave will go when it is
reinstalled, then route it up towards the top of the Post past the top of the Crosstube Gusset.
