I don't want to be exceedingly nitpicky, but 125/7 is closer to 17.857 :)

Not really, 42055 had 112 :)

The official catalog was already available https://catalogs.lego.com/brandCatalog/2HY2019/we/nl/

Great photo! After this, the only strange thing for me is lack of the new biscuit connector

The links from rebrickable point to google photos, not google plus. I don't think google photos will shutdown anytime soon

I am no expert, but I think it has come up with such a battery. It's called 18560.

What about this 11x7 frame, can it be seen on the video?

You are doing the good thing, please continue (if you feel like :) You are reviving creations which would be lost otherwise

You're right, that's more probable

Maybe the best model I have seen here. Will you post photo sequence or lxf? I will build it even if I have to bricklink parts

Is it confirmed that this crane is also designed by Markus Kossmann? Does the second panel have MK sticker?

My main rope, the one that goes to the big drum made of two pulley wheels, has just torn. And I must say it is a huge pain to do the thread routing! Did you use some special kind of reinforced thread? I am using a simple sewing thread.

As for mistakes in LDD file, there was only one significant mistake. 8L axle with stop should be replaced with 9L axle here Also, there were several missing pins and some pins of a wrong type and some pins with no apparent purpose, for instance, inside the gearbox. It is hard to keep track of all of them :) I added one 3x11 panel to the top of the gearbox, I guess it is supposed to go there, there is a row of black pins for it and it is the last panel from 42055.

Hello! I just finished building your wonderful crane. It is really impressive. I did not fully understand its true dimensions from the pictures. It is so huge I can freely drive my 42030 Volvo under it. The rubber tire engagement mechanism is genius and I like the gearbox, the diagonal axle trick is interesting. I love how modular the crane is, it is a pleasure to connect big parts with “pins with stop bushes”, it feels almost like an official set. I hope someone takes advantage of that in the instructions. Unfortunately, the actual functions work poorly. The need to constantly apply pressure kinda kills the pleasure and the tire slips nevertheless, making the movement not steady (it is really slow anyway). I understand that there is a lot of friction in the gearbox. The top two clutches are not fixed (old school solution) and constantly get in the way when you don’t want them to, making the friction worse. The fact that these gears are not synchronized does not help either. The lowermost block with 24 tooth gear is not attached firmly enough. I had to put the blue axle pins or even the 4L axle back in place many times, they are easily kicked out when the movement is blocked down the drivetrain. This mostly happens with boom lifting, not with the rope-driven parts. Maybe there was some solution and I missed it? The upper part of the diagonal axle construction can be easily misaligned. The two 4L axles which hold two halves of superstructure together are highly stressed and also tend to fall off. I connected them with two axle joiners and an axle which helps somewhat. Maybe that part needs more strengthening? The universal joint has slipped off its 4L axle one or two times under load. I think two t-shaped beams interfere with engagement of the clutch responsible for boom lifting. The other three are noticeably easier to move.
