I recently moved and obviously left the MaxJax anchors/sleeves in the garage floor of the previous home. I called both Garage Equip Supply (where I purchased the lift), and Dannmar directly to buy just the anchors/sleeves. Neither would sell them separately, only as a "kit"... which includes the bolts, shims, anchors/sleeves, etc. for $60. All I need are the sleeves that are installed in the floor. Surely I can spend less that $60! Before I pull the trigger on the kit, thought I would ask if any of you MaxJax guys know what type of anchor/sleeve I need to purchase? These online merchants seem promising, once I know the type.

I am not a fan of the sleeves. I have done a lot of concrete work and the sleeves never seem to hold as well. I use wedge anchors, also called stud anchors. Make sure that you use the exact size drill bit that the manufacturer recommends, don't round out the hole, thoroughly clean the holes with a brush and vacuum, and drill at least a half inch deeper than the embedment that you want. If you want to really secure the studs in the floor, I would use epoxy. Also, drill a test hole to see what kind/ depth of slab you are working with...

See if you have a Fastenal near you. They can surely help.

You can easily use a Hilti type drop in anchor. These can be bought at fastening supply houses and even Home Depot has them. I've used these to mount heavy equipment to concrete slabs. TomF makes some good points though as it is very important to use the correct drill and drill bit to ensure the anchor holds properly. Good luck.

Whatever you do make sure a replacement anchor has the same load rating as the MaxJax anchors. Failure would be catastrophic. I would not use an expansion anchor, only an epoxied anchor - I have seen expansion anchors pull out before.

Clarification: When I say not an expansion anchor, I mean the std. types with the small cone at the bottom. Hilti makes a heavy duty expansion anchor that would be suitable, but they are not designed to be removed so if you are storing your MaxJax when it is not being used and then reinstalling it when needed, I'd say the epoxied inserts are a more practical choice.

I can't help but wonder if you'd just be better off buying their $60 kit. If, God forbid, you had a failure of the lift, the chance of having any recourse with the manufacturer went out the window when you used "unauthorized" anchors.

Plus, what's your time worth? I think the most you could realistically save by sourcing the anchor system yourself would be $30-40. I'm guessing you will spend at least 1-2 hours finding, verifying the load-worthiness and purchasing the anchors yourself.

Just a different point of view.

Fastenal should have them or if not, can get them. I used a anchor epoxy to ensure mine will never come out.

Wej-It PD-58 5/8" Diameter Drop In Anchor

OMG don't use an epoxy anchor!! They fail.

Use a sleeve anchor.

Or maybe use the anchor that the manufacturer specifies and install it correctly.

I used the manufacturer anchors with the epoxy. Now instead of being held in the concrete by only the mechanical wedge it's also the held by the epoxy.
The finding for the failure was "bolts secured with fast-set epoxy could safely carry 4,285 lbs each, rather than the 6,350 lbs the designers had planned on. Two independent engineers who reviewed the ceiling’s specifications for the Globe estimated the ceiling’s weight was close to 5,000 pounds per bolt, which is more than bolts secured with fast-set epoxy were designed to bear over the long term."

My point exactly, just saying use epoxy doesn't make it right It should be more like- use the right materials. Just as important is "what concrete is the floor made of."

I agree with your method I also used the Wej-It 58s supplied by MaxJax and set them with extra strength epoxy, belt and suspenders.
OP can get the Wej-It from Amazon for ~3.50 ea instead of the $6 that MaxJax charges. Then you just need a 5-6" long 5/8 bolt, nut and washers to duplicate the MaxJax installation kit.

Thanks Frank! And thank your everybody, for your replies!

Yes Wej-it is the anchor that MaxJax supplies with the kit. see post #10

This is an outstanding system if it is installed correctly. When I install my lift, this is the exact system I will probably use. More expensive, but worth it.

Incidentally, the Wej-it anchors mentioned above are one of the ones that I have had issues with. For this application, epoxy combined with a proper mechanical connection is unquestionably going to be the strongest.

The failure cited in the article above wasn't a failure of the product, it was a failure of engineering- they were way overloaded...
