I'm getting so close to installing mine.. should be bringing it up this weekend!!!! It's starting to get warm.
Is there ANY downfall to putting epoxy on the stock anchor bolts and then tighening them down? Kind of like when you glue and screw wood together... I know people say use one or the other but what harm can come if the anchor bites into the concrete before the epoxy cures?
Not realy concerned with the epoxy being in the bottom of the whole but more around the anchor bolt...
Thanks,

Well it all depends...
How much smarter than those engineers are you?
I guess it would depend on the subject we are talking about..lol
But seriously, a guy on my facebook install his maxjax and he said his anchors got lifted up some or right UP to the bottom of the plate after torqueing the bolts down and lifting a car... so that worries me as far as after i torque them down.. and they are still below the cement but lift a little after they are bolted down to the posts?
I figured that if I put epoxy around the anchors and then did the method of installing the anchor bolt as it bites into the concrete the epoxy would them kinda hold it there if that makes sense...
That's all I was thinking... not trying to make things more complicated but look at most of us on here, we do things well above and beyond what any normal person does to ensure it's right the first time and stays right...
Thanks,

Excellent information! Thank you, that makes me feel better then. I guess I just imagine the anchors that you put in dry wall and if you put the screw in them too far they just come out... that's what I invision with concrete but worse I guess since concrete doesn't move at all...
I don't want to turn this into a how to thread but so far the information in this thread is very very good! Actually I don't think it could get much better with all of the experiences.
When you say make sure you drill a plumb hole what is the BEST way of doing so. Does the actual drill have a level on it indicting that you are drilling a perfectly straight hole? I've used a drill and own many so drilling in drywall and wood for the most part is easier since it's right next to the surface. Drilling in concrete hoenstly does worry me a little mainly because I've never done it before.
Thanks again!

need some help on the maxjax need the size of the bottom plate so i can lay out the area i want the lift in
they give you size for the out side of the posts but need the inside demisions so i can do a mock up to get my truck to pull straight in
jeff
The install instructions suggests that the back side of the plates be about 130 inches apart if you are going to lift a pickup. So it should not really matter what the inside dimensions are.
The instructions also say to snap a chalk line along the forward sides of the plates and from the back side to insure the plates are square to each other. Having that line helps to line up the side of the plates to each other. The instructions also say the plates can't be more than 1/8" off from that chalk line.
I'm trying to lay out where i need to install i don't have a direct straight shot into my work space, need to put mock up column's and try to drive in to see where i need to test drill ( and see if i can really use the maxjax in my garage the picture below show kinda the angle i have to pull in.

Here's some noted from my experience, Clean the holes ,clean the holes....any dust from drilling will cause the anchors to 'slip' and not bite properly
I copied and pasted this from another post I made, I had some issues with the anchor installation this might be of help during your install:
Here's the update, I've got the lift installed and running. It looks like a nice unit. The power unit is quieter than I thought it would be. Installation was straight forward.
I think setting of the anchors is the most critical part of the installation procedure. A couple of things I'll mention from my experience of this one installation. Let me say this first, I'm not a pro lift installer and the following are my opinions only. Drill the holes as per instructions. Do a through job of cleaning the holes. Even though the supplied anchors (Wej-It PD58) are not specificly epoxy style units I'd recommend using a good quality epoxy for additional integrity of anchor bond to concrete. I coated the hole and the exterior of anchors before driving them in. Drive them the 5/8" below concrete as instructions call for, I wouldn't go less.
Now thread the sacraficial bolt with washer and nut finger tight into the anchor, hold the bolt head (you do not want the anchor to rotate in the hole) and tighten the nut to set the anchor, the lift instruction booklet says tighen until anchor is flush with the concrete surface.....The instructions that came in the box of anchors say no more than 4 turns for the 5/8" bolts size. I found that at about 3 turns I could feel the anchors bite hard into the concrete even though they were still 1/8" -3/16" below the surface of floor. I think it's fine (and even preferable) to leave them slightly down because when you tighten the bolts to the base plate if the anchor is not holding properly you'll realize it when torquing the bolts, but with the anchor flush it can contact the bottom of the base plate and feel tight even though not fully anchored in the hole.
Page 13 step 14 of the lift installation manual tells you to install anchor bolts to base plate and tighten 3 to 3 3/4 turns. I believe this is in error, the anchors have already been set with the bolt and nut procedure. These bolts should be torqued betweem 70-95 Ft Lbs according to Wej-it (95) and Dannmar (70).
I found it impossible to get 3+ turns after anchors were set and it caused a couple anchors to pull up (perhaps they rotated in the hole and lost grip ?) and I have to replace them.
Wonderful!!
Excellent info. This may sound stupid but to clean the holes can one use something like brake clean and spray since it evaporates quickly to make any loose particales go away? Did you also drill completely through your slab? And lastly exactly what epoxy did you get becuase I wanted to do the same as far as putting them on the holes and anchors JUST in case type of deal... But at the same time wouldn't that affect the anchor bolt biting into the concrete. Aplogies if these are silly questions but I wan tto make sure 100 % I'm on lock and not come across something and be like welp F... now I have something unsafe or improperly setup in my garage...lol
Thanks for your info! Very helpful!

Your ceiling looks quite low, maybe 7 feet tops. Are you planning on removing part of the suspended ceiling to accommodate this lift? If not, are you sure it's worth while having the lift since I don't think you'd even be able to sit on a chair under it at max lift with a car.
The MaxJax post base plates on mine measure 14-3/4" wide by 13" deep (front to back). Is that what you are asking?

Would you recommend this bottle brush or is it something that needs to be nylon?

this is another really stupid question but oh well..lol
So normally when leveling things on the wall I use a level, which tells me that it is level or not... But with things sticking UP from the garage how exactly do I make sure everything is at the same angle/and parallel with each other.
I saw somewhere that I take the back left corner of one post and measure it to the back right corner of the other post and then switch it and see if the measurements are the same...
But how do I make sure I'm not an degree off IE:
I made a quick drawing.. it's over exaggerated so you can see but that's my problem now... When I measure the left post from the wall I want to make sure that it's the correct spacing from the entire left edge of the post but by doing so I would then not able to match it with the right post? I've never measured anything like this so I feel stupid for asking how to make sure the measure measurement is correct... Directions say snap a chalk line but if I snap a chalk line how do I make it completely straight and not angled any way...
Like this:

I measured from the south wall of my garage (blue lines in pic) to set the columns.
I then squared them (the red lines in pic). Doing it this way, I ended up only 1/8" off when the columns are mounted to the floor/anchors. If I wanted to I could easily take that 1/8 out by adjusting the columns before I torque them.

So I measure from the front corners to the front corners of the post, not the back corners... I did the back last time but I guess it would be easier using the front corners.
Excellent thank you that helps greatly!

Another silly question on the bit. I have searched many sites. I have seen some bits called Masonary bits, some percussion Masonry, Rock Carbide.
Next I figure I might as well buy the hammer drill.. I'll use it again for something. What size is recommended?

I don't mind spending money on a quailty tool I just don't want to buy a hammer drill that is ok at best and then I drill the holes wrong...

Just ordered all of my fittings from here: www.discounthydraulichose.com
Website made it easy to find what I was looking for. They had 90 deg swivels, etc.

So everything i've read thus far says space the anchor 5/8" below the concrete: On the screen shot of the anchor from Wej it' they are saying 1/2"
What's right?
I seem to be getting more confused on the entire process off anchoring these from everything I've seen... IN short.
I drill the hole. Tap the anchor down to X depth below the surface. then put my socket breaker bar on the BOLT head and keep that stationary, and ONLY turn the nut below it.. up to 3-4 turn until it pulls the anchor up?
Then I see to torque it to 90'ft lbs... how do I know the anchor is at 90ft lbs of torque if I can't turn the bolt? I don't have a wrench that tells me the tq setting only actual tq wrenches that sockets attach to.. not a hand wrench...
