Need advice on anchors

[sulfurburner]

I keep running into dead ends so I figure someone would be able to give some helpful advice here

I purchased a brand new, unbranded 2 post lift through an auction company last week. It came with it's own anchors and I'd like to use them if I can. Problem is they're metric and I haven't been able to find a bit to drill them. All we have locally is 5/8" or 3/4" and these anchors are in between the two. they measure almost 11/16" at the wedge. I can order an 11/16" bit online but I'm not sure if this is the right route to go.

Anyone have any experience with metric anchors? They say M18 on the piece by the wedge.

Will a 3/4" bolt fit through the plates on the lift? 3/4" is roughly 19mm (so you'd be taking a tiny step up in size), and it just might be easier to get some 3/4" wedge anchors locally.

That was the best idea I could come up with as well. I wasn't able to source long enough 3/4" anchors locally so I would also need to order those. I figured before I did that I would check here to see if anyone had any other advice

Are you positive they are metric? They look like Redheads to me.

No. To be honest I'm assuming they are because the thickest part of the anchor measures ~11/16", and M18 is stamped on the expando-thingy right above the wedge.

I don't have much experience with anchoring things to concrete so I was hoping someone would recognize this and tell me I'm supposed to be using a 3/4" bit for these

 

[readhead]

Does a 3/4" nut spin on? I would seriously doubt that they are metric. The expando thingy isn't a good place to measure because it slides up to be the wedge.

 

[GMCGarage]

Get some Hilti's or name brand, not the time to be cheap. Toss those out.

 

[Capt Chrysler]

Pitch the cheap stuff. Replace them with name brand and follow their instructions.

M18= metric, 18mm stud diameter.

This is a really good idea I have not tried

Really they don't feel cheap or low quality. I figured the best practice would be to use what the manufacturer sent with the lift

They dont have instructions how to drill, set and torque the bolts?

You cant feel brittle Chinese steel until it breaks and the car lands on your head.

The instructions don't really mention the anchors, just the concrete requirements. That's a good point though.

I'll probably just end up ordering the Hilti anchors. Any tips for shopping for these? do I need to look for a certain grade or weight raiting? I've never bought anchors that anyone's life depended on.

11/16 is 18mm. Those are in fact metric. toss em and buy something that you can count on. Probably cost the same as buying a new 11/16 drill bit anyway.

 

[FrancisJ]

Appear to be 18mm as others have noted. Hilti is good as are Redheads. Tapcons (blue) are JUNK -- have "ok" clamping force, but ZERO lateral or shear force.

 

[moneypit_k5]

OP, how old is your concrete? I was scared to use redheads in my new pad, SO I pre sunk Jbolts prior to the pour.

Hilti has great customer service, and good info on the website.

You will want a Hilti Kwik bolt TZ anchor, sized for the load requirements.

Do the instructions have load requirements for the anchors?

shop was built in 2007 by the previous owner. I have pretty detailed drawings/specs/permits etc. of the build and they didn't cut any corners on anything. I've been wanting to install a lift since I bought the place in 2008 but life kept getting in the way. Finally found a steal of a deal and couldn't pass it up.

I'd go 3/4, that's what came with my 2 post. Also 3/4 SDS bits are very common so all together 3/4" makes for a standard solution. I used a HF hammer drill and a Bosch 3/4 x 12" bit from Lowes - made short work of the whole deal.

If your nervous about using "unknown" quality anchors... are you at all nervous about your "unbranded" 2 post lift?

Can't make a silk purse out of a sows ear...

Honestly I'm not really nervous about using the anchors or the lift. As suspected it was easier just to buy standard anchors/bit than source a metric bit.

I'm sure some folks would never consider buying something like this without some kind of manufactures warranty or guarantee, but they're probably able to spend 2-4k on a brand new one. I picked this one up brand new for the same price used ones are going for online. I guess you could ask the same of someone whose purchased a name brand lift second hand. how confident are you that the PO didn't abuse it and compromise it in any way?

 

[59 wagon man]

drill the holes completely thru the slab. this way if you want to move the lift you can just pound the anchor thru the floor

That's what I usually do, but be aware that this can weaken things a little.
You'll always get some blow out when the hammer drill goes out the other side, and that thins the area around the hole slightly.

If you're on a marginally thick slab, this might be a problem.

 

[moneypit_k5]

OP, just make surr you buy slme lift stands. Takes alot of the scary away.

If its an ALI certified lift you know the design is good. If it isn't you are taking the word of the seller and word of mouth / internet research to see if others have had any issues.

If it's used, and an ALI certified lift, you can look at the components for wear, do some NDE testing on welds, etc. If your really nervous you can replace the critical wear components.

This video was an eye opener for me...

That's pretty scary. the one I bought is a (assuming) china made 10k rated lift also. it's different than the one in the video though. Pretty sure mines an Atlas without the stickers. I'm glad the motor/hydraulic unit wouldn't have been able to lift enough weight to cause the lift to fail. I'll make sure I don't plumb in a bigger pump to lift any 15k lb semi's once I get mine in.
