RE: max jack lift
#16
Darwin award winner semi-finalist: It's been 11 years since I installed my MaxJax. I installed extra anchors in the corner of the garage in anticipation of being able to store the columns when not in use. Fast forward 11 years, I have never not been using the lift, never moved the posts, and it never occurred to me to check the torque on the anchors. Well, today they were still tight, but only to 20-25 ft-lbs. Re-torqued back to 90 ft lbs. Embarrassed that I'd never thought to check.

If you are using the wedge type anchors that require correct torque settings to safely anchor the posts, the torque specs are critical. I used the adhesive anchoring system which sets the anchor into the concrete independent of the bolt torque and thus not so reliant on the torque of the anchor bolts. With the adhesive type. the bolts only need not loosen in the anchor. This allows a much lower torque setting. This was an unintended benefit of my not-so-reliable hammer drilling of my anchor holes.
If you find it difficult to hit the needed torque spec for the wedge anchors, the adhesive style are a godsend.
