D4-9 / D4-9X Four-Post Lifts 22 P/N 5900251 — Rev. A1— August 2021
Installing the Crosstubes
Your Lift has two Crosstubes; each one goes between two Posts at one end of the Lift.
Crosstubes have a Sleeve on each end; Sleeves go over the top of the Posts (before you install the
Top Caps) and then slide down the Post.
There are two ways to get Sleeves over the tops of the Posts:
• with the Posts standing up, raise the Crosstube (with Sleeves on each end) over the tops of the
Posts and slide them down around the Post
• lay the two Posts down, put the Sleeves over the tops of the Posts and slide them down, then
raise the Posts back up
⚠ WARNING Use caution when handling the Crosstubes and Posts. The Posts are not anchored
at this point; if they fall on a person, they will cause injury. You must use a proper
Lifting Device or at least two people when laying the Posts down.
The two Crosstubes must be oriented correctly
: the side with the Crosstube Sheaves must
go on the
inside
of the Lift.
Top view. Runways not installed. Bases not shown. Not to scale. Not all components shown.
⚠ WARNING If you install either Crosstube backwards, the Lifting Cables will not align with the
Crosstube Sheaves and the Safety Locks will not align with the Safety Lock Holes
in the Posts.
To install the Crosstubes:
1. Locate the two Crosstubes, four Inside Slide Blocks (5716075), and four Outside Slide
Blocks (5716076).
2. Orient both Crosstubes so that the Crosstube Sheaves are on the inside of the Lift.
Important: It does not matter which Crosstube goes on which end of the Lift, as long as the
Crosstube Sheaves are on the inside of the Lift.
3. Bend over the two Posts on one end of the Lift and slide the Sleeves of the Crosstubes over the
tops of the Posts. Make sure the Safety Locks on the Crosstubes do not engage on the Safety
Lock Holes in the Posts as you lower the Crosstubes down.
