HD-7P / HD-7W Four-Post Lifts 37 P/N 5900041 — Rev. M — July 2019
When you start routing the Lifting Cable up, it must go between the Gusset Sheave and the Slack
Safety Sheave, as shown in the drawing above.
Important: When routing a Lifting Cable in its Post, it must go
under where the Gusset
Sheave will go when the Gusset Sheave is reinstalled and then, when it heads up
towards the top of the Post, it must be between where the Gusset Sheave will go
and where the Slack Safety Sheave already is. If the Cable is
not in this exact
location
, the Slack Safeties will not work correctly later on.
5. With the Lifting Cable in place, reinstall the Gusset Sheave and the Cable Lock Pin in Post A.
6. Double check to make sure Lifting Cable A is correctly positioned: in the Gusset Sheave, between
the Gusset Sheave and the Slack Safety Sheave, with the Cable Lock Pin
under it.
7. Push the Threaded End of Lifting Cable A up to and through the Top Cap (at the top of the Post)
and
hand tighten it in place with the Nut and Washer you removed earlier.
You only want to hand tighten the Nut at this point so that there is a little play in the cabling. We
will securely tighten all four Nuts later in the installation procedure.
Note: The Threaded end of Lifting Cable A should go just a little bit through the Top Cap. If it is
way too long or way too short, you probably have the wrong Lifting Cable. If it is just a
few inches short, then the Piston on the Hydraulic Cylinder may not have been pulled out
far enough.
8. Make sure the Button End and the unrouted part of Lifting Cable A is under the Large Window,
near the bottom of Post A.
9.
Switching to Lifting Cable C , repeat Steps 1 through 6 for Lifting Cable C, starting at the
Small Window near the bottom of Post C.
10. Once the Threaded End of Lifting Cable C is secured at its Top Cap, return to the Small Window at
the bottom of Post C.
11. Under the Powerside Runway, move the rest of Lifting Cable C towards where the Side Sheave
goes on the Post C side of the Runway.
12. Return to the Small Window and reinstall the Cable Sheave.
13. Double check to make sure Lifting Cable C is correctly positioned in the Cable Sheave in the Small
Window.
14. Route Lifting Cable C into the Side Sheave and then on towards the Large Window, which is at the
other end of the Runway.
The Side Sheave was removed earlier so you can get the Lifting Cable into place.
15. Reinstall the Side Sheave.
