Scholzee .. Look at CO's 4th picture. On the right side there's a white p/u then compare it to the dark car's level. Gives a better perspective of the slope the crane is set on.

It’s because crane op wasn’t well behaved in a past life and as punishment he has to stack blocks everyday before he can sit in his nice cozy cab and relax.
In all seriousness it takes a lot of work and knowledge to be able to get cranes level on that kind of ground. You take a flat lander like me and put him on those hills he’s gonna be a nervous mess for a while.

Ha- throwing blocks down is all part of the fun. Beats climbing a tower.
Today's unit-
Funny story about this unit- it went out about 2 months ago- middle summer blister hot. Landlord for the gov't entity (gov't entity rents building) orders the unit, HVAC manages to find a unit- call us. We go out to help install, crane is there, HVAC guys are there all ready to install.
The gov't entity (renter) refuses to let the install happen. They have to have 30 or 60 days written notice about work being performed at their facility per their contract- blah de blah blah. So instead of getting their AC when it was hot- here we are in sept. at the tail end of hot weather- installing their new A/C. After their written notice.

Once you're up, if you have it cribbed right, it should be fine.
When they want to slide, is in the transition from having enough weight on the tires that your park brake is holding, vs. being anchored by the jacks. That's when they take off - is in that transition.
I try to make sure to get anchored good on a jack or two as I'm coming off the tires to keep it from sliding away. Its kind of awkward if your standing at the outrigger controls- as a 90,000lbs machine slides away from you down the hill.

I always tried to work the boom truck with the nose down the hill for that. Get the front tires up while the rears are down hard. It took a ton of cribbing to get the 5th jack that way, though.

Good observation that explains it well kind of figured it was to level bot picture of slopes always deceiving never show up in pictures as dramatic as they may be.
I had a boom truck run away from me once. I didn’t try it again. Told the guys to get a bigger crane and set the trusses from the street. When they’re sitting on front jacks and take off sliding down the hill it’s a sickening feeling.
What I dislike most is once you get one leveled up on a heck of a slope and you look at the beams and jacks bowing towards the back of the crane because it was pushing so hard downhill. I never could relax after that. Pictures of the jack cylinders bending just play on repeat in my head. Groves were never that bad but the terex’s always scared me.

What I hate are the setup areas with a DOUBLE fall line. Straight up or down one way or the other are one thing, but when the left front pad is blocked up 3', while the right rear starts off jammed tight before you even can get any cribbing, those are the worst. On the slopes so steep I know I'll run out of travel before getting level, I'll throw some cribbing out and drive the front tires on it, gaining a few inches in UP. In the very worst sites, I've had to do that, then max out my outrigger travel (after jamming all the cribbing I can underneath first) and then I've put more blocks under the front tires, as much as possible, let down onto it, and then with the outriggers up put MORE cribbing under for a second lift. I think my "record" is about 4' under the front tires. Those sites are why I carry so much cribbing all the time, and don't need most of it thankfully.

Need a Oil Change while there!!

We have a spot at our yard that has a drastic downhill transition. We nose our crane over it and use the front set of outriggers to pick it up. Its very handy to do an oil change. Plenty of room to sit up under it. We always put cribbing under the front tires in case anything was to happen so it couldn't fall. Beats the heck out of crawling around on your back working on it.Need a Oil Change while there!!
Speaking of outrigger jack travel: spotted this well driller yesterday, 1/4 mile from my place (new neighbors, from California, but good people nonetheless)
he not only had enough travel to get level, but enough to get the entire rig in the air. I often have to settle for just level. Different type of rig setup entirely of course, comparing apples to oranges.
My first oil change on my then new to me National 13110A, was done at my local CAT shop, as I had just done about 10K of work there helping put their new facility togther, and I was probably feeling lazy I guess. If not for the next day's mountain job site, resulting with the front tires being 3' off the ground, I may not have noticed the copius leakage coming from the FINGER TIGHT oil pan drain plug. Also the two oil filters not changed, that I was billed for.

Well driller here can do same, the jacks are not on outriggers to front but rig mounted so can be really long throw(not certain a Good Thing) where can extend a lot as not so much a side load crane fixture.
