lifting platform

I have a large cement garage that is level. Can I just use two rubber mats with a piece of plywood between them and use that as a lifting pad/platform?

Re: lifting platform

Yes. That's a pretty common set-up.

Re: lifting platform

That works well but it will probably shift on you. That's what caused me to build a platform.

Re: lifting platform

If I were you, I would still built the traditional platform with five 4x8 ply wood pieces, I've heard stories of people still cracking cement through one layer of matting.

Re: lifting platform

Lifted on the standard two layer+stall mat so three layer I guess. In about 6 months it found a weakness in my garage slab and pulverized it in one spot. I did a quick fix on the slab and added another layer of 3/4" plywood to my old one which was trashed in the weak spot. Now my platform weighs a billion pounds. I have no intention on looking underneath it to see how my concrete fix is doing.

If I had nothing, I'd probably build a platform with a layer of 2x4 or 2x6 all sandwiched together for the first layer

My original platform moved and I would have to relocate it every couple weeks.

In short, build the burliest platform you can.

Re: lifting platform

Okay, I may go with the 5 pieces. I figure you glue and screw them together, right? You go one direction with two pieces on the bottom, the next two go the opposite direction, then one in the middle on top with rubber mats on each side? That is how I envision it anyway. I guess you can "cut" the rubber mats? That doesn't sound easy. The ones I want are at tractor supply, which are 4'x6'. That leaves a 2-ft square on 2 corners missing. May just put some plywood in there.

Re: lifting platform

That's pretty much it. Cutting stall mats is easy. A utility knife, lube with Wd 40. Snap a line, put a 2x4 or something under the mat and use a straight edge to get the first cut and get after it. A few passes opening up the cut as you go and you are done.

You can glue and screw or just screw if you think you might want to take it apart for some reason.

To answer the next question, use whatever the heck kind of plywood you want for the actual platform. I used birch. Or maybe oak I don't remember. It's perfect. Don't finish it with anything

Re: lifting platform

So you guys are finding that with rubber bumper plates, and dropping the bar onto the slab, it is still cracking the slab? If so, I seriously over-estimated the strength of concrete.

Are you dropping like 200+ from overhead or something?

I'm just getting my garage gym set up and was just going w/ the stall mats, and now I'm wondering if I need to put a platform down.

Re: lifting platform

The most I have dropped from overhead in my garage is 175#. My bumpers are Rogue Hi Temp. I have a single layer of stall mats over concrete. I pulled them up a few weeks ago when I painted my platform, and there is no damage to the concrete underneath.

Re: lifting platform

I have a platform and have dropped 300# overhead without any problems to the concrete. Unless you have a weak slab I wouldn't worry about the concrete.
