Tim,
What's it used for ? I'm guessing it's not pavement milling. How do you mine with one of these ? TFS

Basically you'd put this machine ontop of ur minerals and it would work just like a cold planner...grind up the minerals and load it into the trucks. These machines are only good for certain applications in surface mining such as flat terrain and softer material.

now im a little confused by this.... conveyor on one end and operators cab on the other.... im thinking it may be a little hard to either see the trucks or see where you are going, but i could be missing the bigger picture here, so someone please enlighten me

Tim, thanks I saw this in the bauma post earlier. I have seen rotomills used to mine gypsum here in Colorado, this would be a monster. 5 More in the pit, any feedback on how this is holding up? I can't imagine a more destructive activity than MILLING iron ore, probally saves a heap on processing costs but is it justified?? Thanks for the response.
Now to get nzg to do a model of one, a showpiece on the shelf........loading a 785 truck.

i realize that it can load to the side but not always do you do it that way and on the normal road milling machine you stand in the middle and have a clear view of what you are looking at, in those pictures the cab is all the way to the other end

The cab moves up, down, ... the boom loads off to the side or rear, the machine can work on side hills,and some rough terrain as it self levels... look at the cylinders and track suspension linkage. The cutter head works just like a pavement milling machine. Line it up and go..."GPS equipped I'm sure" maybe laser alignment??
Cutter head maintains depth of cut if desired, or levels high areas... Very productive system I'm sure. With that weight and power and constant production I bet its a huge money maker. It must work as they have had one for some time and are getting more. Fortescue Metals had this machine built for there own needs and worked in conjunction with Wirtgen. They already have several of the smaller models and have been very happy. They just made it twice the size....and production. I'm sure they pepare the working area for these machines so that maximum preformance is assured. I would guess they use dozers, graders and other equipmnet to get a nice flat area for them to keep working 24-7.The machine is designed for hard rock applications or softer materials if you want. My guess would be cutter drum weight or diameter would make the difference on what type of material you are mining.

All I can say is WOW!
A forth coming model of this is required for sure.

Fortescue have 30 odd 777F,s that work in conjunction with the surface miners on iron ore extraction. O/B is hndled by a big fleet O & K & Unit rig trucks, think they have some oddball maybe russian bulldozers there too.

you don't realize how big it is until you see the cab. What a machine.

Here´s what I think is Wirtgens biggest competitor in the suface-miner-buisiness: http://www.takraf.com/de/newsundmedia/downloads/files/surface_miner_en.pdfI don´t know about their current prodct line but Takraf used to build the so called MTS2000. It had a 3400hp engine. It was capable of mining around 3800yd³/h at peak performance. Maximum cutting height was 5ft. Cutting width was 24ft. The machine shown in the brochure (TSM300) is the second smallest one. Short data overview: 1000hp, 570yd³/h, width 13ft, max height 3ft. There is a costom build 1/50 scale model of a MAN Takraf Surface miner somewhere around. I just can´t find any pics of it. Maybe someone else has a picture of it.

Leo, I guess you are talking about the MAN TAKRAF MTS1250 built by Horst Möhler:  The website: www.hm-baumaschinen.deRegards, Martijn
