U see the Matt's under the tires? Jack up put mats under. Lower outriggers. stack Matt's for outrigger. Rinse and repeat til you can level off.

Or the bit more sketchy version:

Lower outriggers. Lift one outrigger (crane is only standing on three outrigger now) and place wood under it. Lower that outrigger again. Lift the next outrigger, put would under and lower it. Do that until you have wood under all 4. Then lift all 4.

Repeat that until you've climbed to the moon.

This I how you do it, can’t really swing mats under the tires.

…And get your lunchbox out of the lower before hand because a latter may not reach

Most underrated comment here.

They are also about 2ft to high in the back left corner . If it's something this extreme I personally would have the lowest corner just barely an inch off the ground

u/Optimal-Age5397 IUOE 10d ago

Seriously. They're way the hell up on those back tires.

u/BigJoe5504 10d ago

It looks like about 2 feet to me

Had a safety dweeb at kweit write me up for no chocks under the wheels of my picker when they were 2 feet off the ground

u/Optimal-Age5397 IUOE 10d ago

Jeez. They're usually more reasonable than that.

I'd walk off that job, easy.

If the PE says its all good... so what you've got to climb two ladders to get in the cab lol.

u/Optimal-Age5397 IUOE 10d ago

Ah. If you look at the right rear outrigger it looks like they didnt jack it up at all. They've got an outrigger plate on top of the crane mat, probably shown in what I hope is a PE drawing so they'd have to be on that. My guess is they couldnt get it any lower with how high the rest of them are jacked up.

u/BigJoe5504 10d ago

Hole up... did they not drop the suspension and lock it off? Those tires look way to far away from the fenders, and the outrigger pad looks lower than the tire. I bet that's the problem right there

2

u/Optimal-Age5397 IUOE 10d ago

They definitely used the suspension to help jack that crane up. At this point it doesn't really matter if they dropped the suspension all the way before they locked it lol its not doing them any favors either way.

u/Jmazoso 10d ago

As a PE who lurks here, I’m not touching that.

u/Ajmd2 9d ago

Honestly it just looks like the outrigger is behind the tire. It's on a single layer of cribbing to make the ground level, and at minimum extension.

TL;DR on this slope that's as close to the ground as they can get the tire

u/BirthHole 9d ago

When I had to do this, my back tires were squat on the ground.

u/prolift46 11d ago

Those mats will have been laid like a ramp before crane got there, drive crane up, beams out outriggers down, jack, then stack more timbers under tires if needed, lower, then add more numbers under outriggers, carry on until you can level out

2

u/Gotagetoutahere 10d ago

I've used this method. Worked well for us.

u/Hanox13 IUOE local 955 10d ago

LOOKS PRETTY SHEEDY… I’ll see myself out.

u/ivdamke 10d ago

That was the description of the Instagram video

u/quiet_locomotion 10d ago edited 9d ago

Any concern or calculations made to ensure the friction of the mats on the slope can hold the crane so it doesn't slip out?

1

u/Fresh-Adhesiveness91 10d ago

Bottom mats look wedged. Don’t have to be exact angle the outriggers have balls for a reason. Weight and gravity do the rest

1

u/jimfosters 10d ago

Myself, I would have a thin rubber mat between the wedges and the pavement.

u/Objective-Eagle-676 10d ago

Lol I also saw the Instagram post about an hour ago

u/DixieNormus369 10d ago

Wonder what they did to keep the cribbing from sliding on the blacktop

2

u/MundaneMusic2720 10d ago

Frictions all you need for that, only time I’ve heard of that failing is on gravel

u/chrishtien 9d ago

All that just to lift up a tree to the backyard
