Lift sizes?

[dreamingmuscle]

Ok my pole barn should be going up next week. My builder is going to drill a couple of 14x14 holes where I wish my future two post lift to be. Problem is that I haven't decided on which lift to get. And any lift is a few years in the future due to budget restrictions.

Is there a common foot print for two post lifts, that I can use to tell him where to drill the holes? I mean they all should be around width should they? A 9000 lbs lift is what I'm thinking would be right for me.

If you drill any holes before you have the lift in your shop, you'll hate yourself! Get the lift, roto-hammer the holes with the posts in place.

14 x 14 what ?

Just thicken the slab where you are going to put it. I'd go with 8" deep concrete on a thickened section thats 12" greater on each side than the footprint of the metal base, centered upon where you intend to put it in present day. That means you can move it 1 foot in every direction from the initial spot without any worry, once you have the beast in-hand. I would use epoxied threaded rod for anchor bolts, despite the dust, be sure to put an air blower nozzle down inside the drilled hole to blow out the dust. Armed with a running shop vac in the other hand, it helps preserve your respiration But getting the dust out is imperative to the epoxy getting a good solid bond with the concrete.

I've been involved with moving a lift where the holes were drilled in advance to a "pattern."

Somehow they would up damaging some of the studs and bent them over after putting the lift over them.


I don't know if they do in all states, but the local Home Depots rent hammer drills.


If however the "drilling" the OP mentions is due to some concern about unstable ground, I'm with Matt-I, you don't want just the area under the "feet" of the lift reinforced.

You need an area large enough to keep the lift from tipping over, not just reinforcement for the vertical load.

Have you ever looked into the concrete floor recommendations by various lift manufacturers to get a general idea of what my be needed? Most recommend a minimum 4" floor and that saw cuts are adequately away from the base. Just make sure you have at least 4".... go 5" to be sure and you should be 'good to go' to bolt your lift,anywhere.

I think for a 2 post most lift manufacturers call for 6" with the big capacity units 12k and up, and 4" with rebar being OK for smaller units ?

14 x 14 what ?

He will drill A footing hole 14" round by 14" deep where the lifts post will set. No anchors will be installed until I get the lift. I just need to know if there is a industry standard for how far apart the post are from each other.

In my research for a 2 post lift, I was able to download a spec sheet for each lift I was interested in. All the widths differed slightly. I am in the build process now and I dug 2 haunches under where my lift posts will end up. I used the dimensions off the spec sheet for the lift I was going to purchase but changed my mind. The lift I decided on was within 2 inches in width of the original so it worked out OK for me.

Do some research on a lift you think you may like and use thone dimensions.

I had my contractor do just that. I told him about a future lift, he basically said "Where"? I did some research and picked a spot 12 feet in the "bay" side. He said "no problem, it just a few more scoops to take out".
I got 2 pads 3' x 3' x 12" deep where the lift will go.
Don't skimp on depth. I don't care what some says is the minimum is. An anchor that inserts 4" needs 6" of concrete so it doesn't blow out the underside when drill through. If you have a 4" slab and drill through it, the anchor has only 2-1/2" to 3" grip area. Epoxy anchors won't help. You will have problems, crack concrete or stud that won't hold the lift.
If you have the chance now, prep the area for the lift, nice large foot print pads, as deep as you can stand (12").
no future worries.

I had my floor poured two weeks ago. I put in an area which was about 3X4 centered on the lift I believe I will be going with, but it also works for another brand. The thickness in this area is about 8-9". My primary lift company specs 6" concrete. I also installed radiant heat, but did not run any tubes through those areas.

Good luck,
