Nice video! I bought my Maxjax about four years ago, but I didn’t trust my concrete so I cut a 12’x4’ pad, glad I did! Existing concrete was shit, barely 4”, the mesh was all the way under it, plus it’s 60 years old. Now I’m 12” thick, undercut, lots of rebar, all according to the manufacturer specifications plus. Ready to start drilling. My question is, how far did you space your posts, and do you like the spacing? I have a ‘74 Corvette, basically the same as yours.
You have made some smart moves there. My post are 104” apart. It seams good, sometimes I think I would like them a little farther apart but then I’m crowing my next bay. I would not go any closer, but it may depend on the car(s) you are lifting.
Great tutorial bud, hey once we start forgetting about the hood being up, it is time to not work on mechanical tasks, means reaching the point where the cheese start sliding off the cracker, time to chill out! 😂
Read the installation instructions, your not supposed to use a pneumatic air gun to install the bolts, it's right in the manual. I'm sure the engineers know better than you why they instruct the owner not to do this and I believe it's a safety factor. When you use the gun you are applying undo stress on the bolts as well as the jolting torque applied into your concrete. Also, you didn't torque your bolts with a torque wrench as per installation instructions. Do you honestly think that all 5 bolts are within the proper specs that the manufacturer specifies by just using your air gun? Nice of you to do this video but you shouldn't show things that could cause yourself or another owner problems in the future.... again, read your installation manual. I've had my hoist for about the same amount of time as you and I take safety quite seriously when I'm getting underneath a vehicle held in by 5 bolts in concrete and I'll be sure that I follow the manufacturers instructions. I'm not an engineer but I'm sure an engineer came up with those installation procedures. I also bought 1/2" silicone plugs off of Amazon to put into the bolt holes when you remove them from the floor. It keeps dirt and moisture out. I also bought longer bolts. After measuring the plugs in the concrete I found you could get a 1/2" longer bolt to hold the hoist into the concrete. I know it doesn't sound like a lot, but in the interest of safety more threads of a bolt holding the hoist are worth the effort in my opinion. Makes me feel safer when I'm under a 3,500 lb vehicle on the hoist. Again, I don't mean to point out more issues, but your hoist arm locks, the part you lifted up to move the arms are adjusted or installed wrong. When you lower the hoist, the rod that protrudes through the bottom is supposed to hit the flat bottom plate of your hoist and lift it up, that way you can move your arms without having to lift it up. When you raise your hoist it lowers the lock into your arms so they don't move. Again, it's all in your installation manual. Please don't take these comments the wrong way, we are all car hobbyists and I feel it appropriate to point out safety concerns when I see them. I don't want anything happening to you or anyone else. Love your car and I hope it will be on the road soon.
