GrandPrix Two-Post Lifts 25 P/N 5900209 — Rev. D3 — Feb. 2020
The following drawing is a top view of the components of the Top Trough. Not every component is
shown, just the components relevant to installing the Lift. The Offside Post is on the left, the Powerside
Post is on the right.
Preparing the Top Trough
The Top Trough goes between the two posts at the top of the Lift.
To prepare the Top Trough, you need to:
• Route the Lifting cables.
• Route the safety cables.
• Connect the hydraulic cables (but not the hydraulic lines).
Tip We strongly recommend raising the Top Trough off the ground when performing these
preparation tasks; a saw horse works great for this, for example.
Routing the Lifting Cables
The Lifting cables move the Lift Heads and Lift Arms up and down.
To route the Lifting cables:
1. Make sure you have two Long Cables and two Short Cables.
All cables have ID tags showing their lengths.
2. Extend the Cylinder Rod until the Pullblock sheave pin lines up with the Access Hole in the Top
Trough.
This can be done by carefully pulling the Cylinder Rod by hand or carefully using an air gun
(remove both plugs, insert air gun in port furthest from the Cylinder Rod, push air in).
⚠ CAUTION Be careful not to damage the Cylinder Rod when extending it. Do not exceed 50
PSI if using an air gun. If Cylinder Rod is not extending, stop and use a cable puller
or other pulling device. Keep hands clear of pinch points.
