D4-9 / D4-9X Four-Post Lifts 32 P/N 5900251 — Rev. A1— August 2021
About Cable Sheaves
Cable Sheaves route the Lifting Cables towards the appropriate Post. There are six Cable Sheaves
under the Powerside Runway, four on one end (two stacks of two Sheaves) and two on the other end
(two stacks of single Sheaves). Additionally, there is a Cable Sheave on each end of the Crosstubes, 4
four total.
Because the Lift can be installed with the Power Post and the Powerside Runway in either of two
locations, the Runway Sheaves can also be at either of two locations. The two double Runway
Sheaves are always on the Piston end of the Powerside Runway, as shown in the following drawing.

All Runway Sheaves should have been removed when unpacking the Lift. The following drawing shows
how to reinstall the Runway Sheaves when it comes time to do so.
