Maxjax welding recessed epoxy anchors

[Slowbolt]

Idk if this has been done before. But I wasn’t having luck with the wedge anchors. I poured new 12 inch thick patches for my garage floor to have enough floor maxjax specs.

One side locked up tight. Every time I check the torque they don’t move at all. The other side had one bolt that would torque to 90 but after a few lifts one bolt would turn an 8th of an inch to get back 90ftlbs every time. While I couldn’t tell if was pulling up I thought it had to be. But I had drilled all the way through. I know the epoxy system was designed for threaded rod as well do so I figured I would marry the 2

Anyway it took up space I had in the hole and worked great. Maybe this might help someone else idk. Have a great thanksgiving!

That happened to me. I spoke to an engineer I know and he told me that concrete epoxy is STRONG. I ended up using it on all anchors.

I've used Hilti brand epoxy for years, professionally & personally. I would not trust anything else.

OP - I've seen some screwed things before, this may take the cake

I trust Hilti products. Other companies; Simpson for example, are also known for quality products, select your solution with care.

So you don’t approve then I take it I ran the idea by a mechanical engineer buddy of mine. He thought it would help in my situation. Not advice on how to anything. Just sharing what I did.

Maybe I didn’t mention that I welded the rod to a wejit epoxy female anchor. You can epoxy just threaded rod in the floor to hold up a lift. Maxjax sells these female epoxy floor anchors as well. I just married the two
cuz my holes were 12 inches deep.

I've used the Hilti epoxy in some severe settings and it never failed. This was at work under severe conditions.

This is them before I welded a rod on the bottom. Can’t possibly see how what I did would make them more dangerous. All I did was add more contact for the chemical bond. I’m sure they would have longer if everyone had 12 inches of concrete to work with. You already need 6 inches to use these.

Anyway don’t do it this way. It was just a way.

Ah, did not realize this was mainly a wejit product

I figured that was the case. But it is the internet. So no matter what you’re always wrong. Happy wrenching!

Used those wejit epoxy anchors on previous 2 post lift install. Worked out just fine. Moving the lift to a new garage/workshop. Spoke with Hilti engineer about their Hit-Z anchors. He said they use these for overhead epoxy fastening conditions with large conveyors as well as large ground mount equipment. Decided to use these on my new install, along with their HY200 epoxy. They claim this system does not require cleanout of the holes, but I plan to cleanout anyway. Not bashing mechanical anchors, just believe modern epoxy system is superior if done correctly.

I am using epoxy

Does Hilti make a 5/8s female anchor?

Does Hilti make a 5/8s female anchor?

I didn't see anything when I was searching.
