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.
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.
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.
Spacers go between the Post and the Sleeve.
To install the Crosstubes:
1. Orient both Crosstubes so that the Crosstube Sheaves are on the inside of the Lift.
It does not matter which Crosstube goes on which end of the Lift.
2. 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.
3. Stand the Posts back up again and carefully move the Sleeves all the way to the ground.
