The Largest Bucket Wheel Excavator in the world built by Krupp,
seen here crossing a federal highway in Germany en route to it's
destination (an open-pit coal mine). It is cheaper to walk a
thing like this than to construct or re-assemble on-site.

* Stands over 95 metres tall
* Is over 215 metres long (2.5 football fields)
* Weighs over 45,500 tons (yes that's 45 thousand tons!)
* Cost $100 million USD, took 5 years to design & manufacture
and 5 years to assemble
* Only Requires 5 people to operate
* The Bucket Wheel is over 70 feet in diameter with 20 buckets
each of which can hold over 15 cubic metres of material. A
6-foot man can stand up inside one of the buckets.
* It moves on 12 crawlers (each is 3.6 metres wide, 2.4 metres
high & 14 metres long) - 8 in front and 4 in back
* Has a maximum speed of 10m/min
* It can remove over 76,455 cubic metres of overburden each day

Haven't flown over it for a few years but there used to a very large
bucket wheel excavator operating at Goonyella (CQ coal mine) which
looked pretty impressive from 1000 feet above.

Sounds way too cheap, or way too heavy. They talk similar money for
the larger draglines operating in local mines, which probably have
similar dimensions but weigh a lot less AFAIK.

There's heaps of massive machinery operating in Australian mines which
tends to be overlooked because most of it is in out of the way places.
All of it is assembled on the spot as it's way too large and too far
from anywhere to move in one piece.

40 minute quarter mile. And I thought my FJ40 Landcruiser was slow.

You're assuming a rolling start. It could take a while to get 45million kgs
up to top speed, even if it is only 10m/min. :-)

I bet they wish they could still use slaves, though.

They use similar excavators in the open cut mines in the Latrobe
Valley, in Victoria. There's quite a few of them there. They might be
smaller, but not by much. I grew up in the latrobe valley and have
seen them up close plenty of times, and have always been amazed at the
sheer size of them. A few times they have moved them from one opencut
mint to another (say from Yallourn to Morwell), they do it overnight
down the freeway, takes them all night.

In the case of the German unit, hardly any of it has to be imported - that'd
make it cheaper.

AFAIK it's still there. And it looks a whole lot larger aagain when
you're standing on the ground next to it.

Nah, it's an error I'm surprised no-one else picked.

By my arithmetic it works out to a cost of around US$2,200 per tonne,
which is pretty close to the current price of raw steel.

No one can manufacturer anything for the price of raw steel, be it a
motor car, or a bulldozer, or the Sydney harbour bridge.

US$22,000 per tonne would be nearer the mark -- more likely it weighs
4,500 tonne, which would put it in the same league as some of the
larger machines operating in Australian mines.
