BendPak XPR10 Setup

[6869704x4]

Finally got one. Pissed that it is made in China. Looking it over All the welds are very consistent with no splatter. Can't see penetration but oh well. All the parts, pulleys, cables, hoses etc look well made. A couple of pics from the first day.

I didn't have high hopes of that fifty year old concrete meeting specs and it failed, just barely. Thickness is around four inches. Also have no idea of the psi or if any rebar. So, I have two options. Increase the size of the base plate and anchor it to spread out the load? Big unknown there, or do this.

4" slab is normal.

4" slab seems like it's within most safety standards until you exceed 10,000 lbs it seems, for a lift with above-ground hydraulic lines. You could always drill the slab to double check thickness if you're not sure. Been looking into lifts lately and that seems to be what I've been seeing


Just put the heaviest rig you have on it, if it doesn't fall over you're good

 

[PAToyota]

How is it failing? Cracking the slab? Fasteners pulling out?

BendPak wan'ts 4 1/2" A couple of holes punched through at four

If I felt good about the concrete I'd do the Hilti epoxy anchors and call it a day.

4" is thin for a 10k right?

You can make some load distribution plates that bolt under the lift posts and spread it out more. Think of big trapezoids under each post, bolted to the concrete through the lift posts and at the ends.

Otherwise you're cutting the floor and pouring caisons.

I'd go bigger plates to spread the load, but would weld or bolt them to the lift so that the lift doesn't just pull thru and pivot on them


I wouldn't want to cut out and pour some cubes, then have those pivot out of the ground

I don't get why they don't have load spreaders anyway. Putting that huge leverage on a single point seems questionable. I guess it works, though...

Like this:

Every lift I've been around was bolted to a 'load spreader' and not just a single point. Load spreader being a slab of concrete with rebar in the mix

My thoughts on increasing the size of the baseplate were to cut a notch in a plate to surround the baseplate on three sides. Then weld the plate to the baseplate and Anchor it to the slab. This will give me the six anchor bolts in the base plate plus the anchors in the added plate.
I have two pieces of 2’x2’x1/2” plate to use.

That'll definitely work. Just has to be good welds. Lots of pressure right at the butt joint.

Any 3rd dimension you can get into it will stiffen it a lot over flat plate.

The minimum requirements regarding the concrete depth are reduced by 1,5 inches when the reinforcing plates are installed.

Which means the reinforcement set can be used for concrete depths of 6,5 inches.

Without the plates a minimum concrete depth of 8 inches is required.

$200 for the idea and the plates.

$500 to have some asshole with a license punch some numbers into a computer so that a filthy Virginian with a license doesn't make it your fault when some dumbass buys your product and kills themselves lifting a city bus (plus all your other overhead)

It's not the thing that costs the money. It's the giant fucking target you put on your back by being in the above the table business of selling the thing that costs the money, drives the overhead and is reflected in the price.

I suck at the build thread.
Getting it level

Using string and a laser.
Right side needed to come up 3/4. You can see the plate under it. Drilled holes in the plate with the mag drill I post about in the products that kick ass thread .

Level and plumb ready for power pack. First test was a fail. Right cylinder leaked. Puddle is from replacing it. Then, up with the 2nd heaviest truck. Changed the oil while it was up there.

Then, up with the heaviest truck

Then the left cylinder started leaking, BP sent another and got it swapped. So far so good.
No reinforcement plate yet. All the anchors torqued down real good except one. That's because I managed to put it right on a small crack I didn't see.
