Advice on lift anchors...

[monty007]

Hi all,

New member from Vancouver Canada! Love the stuff you guys do on here. Finally got a MaxJax lift for my short-height garage. I used the wej-it anchors and did everything to spec as per the manual. I have used the lift successfully with two different vehicles: 2015 Mazda 3 (2931 lbs) and a 2011 Subaru Forester (3250 lbs). Both were lifted effortlessly and level. There was no deviation of the pillars - stayed level.

My concern is about the anchor bolts. All of them are torqued to 100 lbs using a torque wrench. My install is more of a permanent install so the pillars have not been moved. Before lifting the second car there was one bolt that was looser than the others. I have checked all the anchor bolts now and everything has been torqued up to 100 lbs but should I be concerned? My concrete is 5"+ thick. Only went to 5" because that is what the manual said.

Thanks in advance!!

5" of concrete is enough. 100 foot lbs sounds like a lot. What size bolt?
100 would be about right for 3/4"

kit comes with 7/8" bolts and matching wedge style anchors. Link here: http://www.toggler.com/wejit/powerdrop.pdf

It does say 90 lbs - maybe I over-torqued the bolts?

Usually lifts have 3/4" bolts and torqued to at least 100 foot pounds. The bolts can move and you should check the torque on them periodically, if one consistently moves, then you may need to pull it out and epoxy a stud in.

Interesting in that I installed 3/4 inch red head wedge anchors and some of my bolts with the maxjax do the same thing and they had me concerned. The installed said just keep re-tightening them as tightening the bolts secures the wedge more in the concrete. But I do have my concerns as well. More info would be wonderful!

You should follow the manufacturer's specs to the letter. That said, you probably didn't damage anything by going to 100 instead of 90. You should test them for torque periodically. As long as they can be torqued to spec, you should be ok.

I know that you earlier stated that you used a torque wrench but did you also use an impact to tighten them first?
