2 Post Lift repair question

[N_Jay]

I have to replace the carriage on one side of my Advantage 2 post 10K lift.
(They are sending me a new one, under warranty)

I have two choices.

1) I can lift the carriage out the top.
I need to measure, but am fairly sure I have enough height.
I can use the building roof trusses and a chain hoist to do the lifting.

2) I can unbolt the column and lay it down.
What I am not sure of is once I remove tension from the anchor bolts (and probably bump them side to side a bit) will they retorque properly?
If they pull out I am going to have to go up a size, or use an epoxy kit.

Either way I have to take the cross bar, cables and all off.

Thoughts??

If it were mine I would go out the top.

Same. Go out the top.

That is what I thought, but the company recommends laying the post down.
They have no notes as to whether the anchors may be affected.

I would lay the post down as a last resort. If you can get it out the top then you are doing less work in the long run...

Thanks, I was less worried about the work and more about ending up with nag anchor bolts.

As for the "work" it all depends on how much the carriage weights and how well I can rig a hoist.

From what I remember when I installed my two post, the arms are the heaviest part. The actual carriage isn’t light, but should be manageable.

I'll know ad soon as the new one shows up.

Fastest? Going out the top, but I would be very wary about lifting from the roof trusses (wood trusses I'm assuming?)
Safest way I would think is getting your hands on a railroad jack or even a high lift. Lift the column and crib until it clears the anchor studs then slide out from the studs and tip over. Some extra hands and some brewskies should cover it

The roof trusses are welded steel tubing.
Watched the builders climbing all over them during construction.
Plan on spanning two or three to pick up the load.

If the part is over 100LB, we will probably half to lay it down.

As for machines I'll have to see what I can borrow. Guessing a skid-steer with forks.

Ok, pulled the pls one out the top today.
Not as bad as I feared.
Just my son and I a small chain hoist, and a couple of ladders.
Once out we could easily see the bar on the back that catches the safety latch was bent.
I am going to have one extra set of hands to put the new one in.

I really need a 15 +ft winch, not a 10 foot one, as we had to set it on a platform 1/2 way down to reposition the winch chain.

Good to here, I may change the pad/sliders on mine in the foreseeable future!

 

[N_Jay]

When I found a little looseness I figured a slider cracked, not a bent part. When I got the new carriage, it did not have sliders, so I called.
They said they rarely see bad sliders.

Mine look fine (very little use so far)
I will lube them up good when I reassemble.
