Drilling and anchoring 2 post lifts

[mooman]

i have used an impact on hundreds of anchours , find that it " seats " faster and no failures to date.......in all fairness this hasn't been on lifts and or such, mostly staionary equipment , tables and angle iron shelves for concrete steps attached to the buildings foundation.............usually burp the gun and finish off by hand...........

I used to be a DC local 602 apprentice and HATED those shields. That being said, I never had a 400lb VAV fall out of a ceiling or loosen up.

This is new construction and I'll have about 15' at the peak. I will be lifting fairly tall vehicles(VW busses). Will I need extensions or can the cross over's be put on the floor?

swharris: How much do the buses weigh? If they don't weigh over 3000 lbs, then we would suggest a 9k lb. floor plate lift (without an overhead bar) or a 2-post with column height extensions. Good luck with the construction project.

Why isn't it more common to add an epoxy adhesive to these bolts as a kind of insurance. For a lift, I can't see the downside. But maybe there's a reason?

I've yet to finish reading the thread, but Hilti's install instructions make it pretty clear that a hole for a wedge != the right hole for epoxy. I did not know this till earlier this week, when I helped install Spyder/Marc's lift, we used Redheads+epoxy. You need a 1/8" oversized hole to epoxy the stud in, otherwise the epoxy isn't thick enough and won't hold properly. This is according to Hilti's manual as well as a rep.

If you wanted to be super secure and have the best of epoxy and mechanical anchors, you could do what I do for Tower anchors in ledge. We would step the hole so that the mechanical anchor was in the smaller hole, then after it was torqued to spec, you can add grout or in this case epoxy. We have used epoxy too, but grout was more common, but we have a longer bonding length than you could achieve in a floor. Most of our anchors are either all grout or epoxy, the mechanical style are grouted after tension has been achieved.
