First: The WHY and how

What drives me forward, and makes me built models in the first place, is the technical challenges and the creative world that it offers. Some people paint, some people carve stuff in stone, I built models.
As you have most likely seen on the other parts of this website, the hobby goes back quite a while, and the latest projects include the custom Scania R620 heavy hauler, and the custom flatbed to go with it.
Now it's time for something else.. something bigger and much more complicated, something that can be a greater challenge.
Mobile cranes caught my eye years back, and after looking far and wide I must conclude, that no plans, kits or anything like it, exists. All you see is scratch build. (When it comes to working, RC models)
There are many forums where people show some here, some there, and a little bit everywhere... but I have found no site giving the full story, from start to finish. That is what I intend to deliver here.

Why did I choose the LTM 1500-8.1, and not something else?
The technical side of these cranes is a stunning piece of machinery, where fragile electrical components interact with powerful hydraulics, forming a crane often capable of lifting it's own weight!
The 1500 is not the largest crane, and obviously not the smallest either. It is not the crane with the largest capacity, nor is it the most expensive. So why choose the 1500 then?
Well.. First of all, I think it looks great. Proportions between crane boom and the rest of the vehicle are good, and it’s an impressive beast that clocks in at 96t. Lifting capacity is a stunning 500t (3m radius). The very fact that it has eight axles makes it large enough so that I will have space for things, and yet it is not too large for the track. The LTM 11200 would be too big, so I’ll leave that for someone else to build. :-)

How are you going to go about this built, you might ask.. with good reason too! It is like the old question: How do you eat an elephant? The answer is: One bite at the time!
It's going to be a looooong project, and I will need external assistance fabricating some of the stuff (milling, laser-cutting, bending). I really dream of owning a mill, but for now I have to keep asking Santa, and try to be as nice as possible until then. Another huge factor that does effect the project duration is funding... and that's where the plans and blueprints come in. Autodesk Inventor drawings, exported data files for mills and such, PDF's and so on will be created for key components, and I will be selling those when they become available. Not to make me rich or anything, but to get a little back from the many, many hours that will go into the project, and to be able to boost progress.

Other than that, it's just a question of beginning with the right parts, and plan ahead.
I bought the axles, wheels and rims, because they dictate the precise width, axle clearance, and a few other key measurements. I will keep it all as close to scale (1:14) as possible, but I will have to deviate ever so slightly now and again. Next is the suspension, then the outriggers, then the steel frame (spine of the crane).. and so on... and the many many challenges that will come along the way.
