For those concerned this crack is a surface imperfection it's not a deep crack!
Why are the anchors in line with an expansion joint or saw cut in the concrete?
Yes good question that is why the anchor failed.
Hi Bryan. I watched your video and bought a Sika anchoring adhesive fix for the one post's like you did. And bought also a bucket of anchoring cement to apply on the 2nd post's. Sika applied anchors has failed around 100-pound torque, and the nuts ended up on the treads. But the cemented side anchors did pass over 130 pounds of torque, no lose even a bit. No product can beat the cement's strength I believe.
I used the Simpson Strongtie 2-part anchor epoxy. It was a twin tube gun with mixing nozzle, super convenient.
post is right on a stress crack be careful.
To hell with wedge anchors! I was installing my 2 post 6 months ago and I installed one and had a problem with all the rest. I said screw it, pushed them all through the slab and went with 5/8 threaded rod. I used two tubes of AC100Gold epoxy and used blue lock tight on the nuts. They are NOT going anywhere. I feel safer with a single epoxied threaded rod than i would with every single wedge anchor "Holding".
Roger That!
@@Bryan916just asking why you didn't use a threaded rod of the same diameter that screws into the epoxy.
From what I seen that way it will not come out. Only asking?
@Badeau68 This was the first time I had an anchor come back out. I learned from this experience that wedge anchors suck. I'll be using epoxy and threaded rod from here on out!
Lift manufacturers will void the warranty if you dont use wedge anchors. They provide them with the lift. Even tho we know that using anchoring adhesive is better, its just what they say to do. The wedge anchors will work fine if the hole is perfect. But whens it ever perfect.
How do you use threaded rods? I hear a lot of people mentioning that but I have no idea.
Thanks for the info, as I have 1 for sure maybe 2 additional anchors that kind of sketchy to me, However, I will use the 5/8 rod and adhesive as replacement all others are good.
For sure
Well done, Mate! All Hold bolts should be epoxy high-strength fixed into concrete. Do not use Tru-Bolts, Dyna bolt or USA wedge bolt
Great video buddy. Have an issue with two bolts in my shop. This is what im goingvto do. Thanks.
This is why I used a 2-part epoxy with 5/8 x 6" threaded rod to secure my lift. It hasn't moved at all in 4 years.
Standard size is 3/4" Rod or anchors for 2 post lifts. Most, if not all lifts, come with or recommend 3/4" anchors. I used Hilti Hit-Z 3/4" Anchors (7/8" bore hole) with their HY-200 epoxy.
How does the threaded rod work? How do you screw it in?
You fill the hole with the epoxy and press the threaded rod into the hole. The epoxy hardens and secures the rod. Then the nuts are threaded onto the portion of the rod that extends beyond the top of the hole. This secures the baseplates of the lift. The epoxy is incredibly strong.
Great video. Thanks
Are you really torquing the bolt or is it just frozen in epoxy? How are the bike threads engaging?
Please keep an eye on those bolts. 4 post not as critical, but a 2 post lift should be a minimum of 18" from any crack or joint in the concrete.
Looks like 3 of your bolts on right on the pad joint.
If you have to do it again bring the temperature of the tube up by putting on your defroster in a vehicle, it flows so much better.
We deal with 2 part epoxies all the time installing 1½" dowel bars into concrete roadway where I work.
Stay safe
Hey, what do you guys use to epoxy bar??? I've got 104 5/8" 6 inch long rods to install and there has got to be something much cheaper than the stuff here. Sika hardens way too fast for this job of mine to not cost a grand in glue! Thanks!
My Triumph lift instructions said minimum of 6” from an edge or seam.
Who ever installed your lift put it right on an explosion joint. I'm installing a two post forward lift and will use that on my bolts. But I will torque them as soon as I put them in. I will just put a lot of the compound on the bolts before inserting them.
Cant argue with that, that's the way to go! 💪
this morning i was telling my wife how my anchor bolts to my lift were pulling out and then this video came up. so people our computers are listening to us. thanks for the vid. i did have concrete break and had a car nearly kill me
Great information, thank you have a BLESSED day
That crack scares me 😳
Its only near one bolt.
Thanks for the video. Do you have some advice for the case of holes that are not drilled all the way through the slab, so the inserts cannot be pounded down? I wonder if I can tighten the nuts until the inserts pull out?
yeah use the nut to draw it up by using a big socket or maybe a adjustable wrench to take up some space.
I'll definitely keep this in mind if ever needed🤝
How much achor fix did you put in the hole?
Hey Bryan. Awesome video! I'm about to do this to a new install. I need to do 3 on 1 side. Is there anything additional you might recommend doing? Just want to make sure before I take care of my lift. Thanks in advance!
Don't bother with wedge anchors. Use 5/8 threaded rod with epoxy. Wedge anchors don't have enough clearances around it for the epoxy to really grip on. I think the hole i drilled was 3/4 (was trying wedge anchors initially) and the epoxy stated a 5/8 rod in 3/4 hole. SO worth it. Honestly it was really easy.
I hear a lot of talk about 5/8 threaded rods. How is that done do you just put the cement in the hole and insert the threaded rod even though the hole is a 3/4 inch?
Is it possible that your anchor bolt failed because there seems to be a large crack in the concrete running directly in line with where the bolts located?
I doubt it because I had two other anchor bolts do the same thing nowhere near the crack.
I’m going to do this to all my bolts during install just for peace of mind …
I tip that you might already know is to place/tighten another nut on top of those existing nuts after you've torqued them into place and they'll never move. Essentially a "lock nut".
It’s not the nut loosening it’s the anchor bolt slipping out of the concrete. It essentially loses grip on the surrounding concrete.
A lock nut would not have helped at all in this situation.
Your cement is cracked where the bolt is , I'd cut a square in cement and refill it with 5000psi cement.
its a metal filled polymer.
Wait u ised epoxy on a wedge anchor? How is the wedge supposed to move and swddge in if the epoxy is alrady dry and it cant pull up to wedge it?
Shouldnt it have been torqued right away to wedge and that holds it before it dries, then epoxy dries and maybe makes it stronger then?
Yes If its a warm day out and the cement/epoxy dry's fast then yes torque it down right away. My case was a bit different as I stated in the video.
Wedge bolts are the worst lforvertical applications. I always use expanding bolts and NO glue.
What are expansion bolts? Just asking
Torque spec is 150ft lb.
I got as far as '' pound it into the dirt '' at that point I would be cutting the concrete and putting in a block and some steel plates ...
you are using 2 part epoxy, there is no cement in that tube, its a part A and part B, that tube should have came with a nozzle that mixes the epoxy when you squeeze it out of the gun.
Correct!
You have to put another plate
cut and pour new bases for the lift. That crack and repair looks sketchy as hell. How do you know that the bolt shaft is not bonded to the lift base plate and that is what you are torquing against. Your lift your life.
Quick reminder 11 more bolts are keeping the lift upright! The Cement/epoxy is deep into the hole my friend not just at the base plate of the lift. Do you know how much torque 120 ft. lbs. are? There's no way a little cement on the tip would stand up to a 120 ft lbs. of torque. 😂
150 foot pounds
you got to be shitting me!
Dude... To make it easier. Cut about inch and a half off the nozzle. Makes the opening way bigger to apply the adhesive and quicker!!
No you want it to mix well, It mix's by going though the nozzle!
Is your life worth taking the chance on that holding. The crack is the reason that bolt did not hold. Glue in not the answer. You should have cut the concrete and installed the lift in the right of concrete and rebar enforced.
My life is not in danger because of a small crack near 1 out of 12 Anchor bolts claim down! You obviously don't know what you're talking about. This stuff is used in construction to anchor down foundation bolts for very heavy objects like houses and apartment buildings a two-post car lift is nothing for this stuff.
@@Bryan916 i had the concrete break and the car dropped seconds after i got clear of it to grab a tool.
@narcissistinjurygiver2932 That sucks, You had some other issues going on!
@@Bryan916 bad concrete
