Betcha the steering wheel is easier to turn than my Kubota B7100!:p

Every once in a while we see a documentary on the Oil sands that will show such trucks in operation.:D

Sadly, while in Alberta I never took the trouble to visit the mining sites even though I was in Ft. MacMurray.:(

I especially liked the oil renewal system. It burns engine oil which requires constant refilling of the crankcase. 110 gallons of crank oil.

I followed a police escort a couple of weeks ago. They were escorting an outfit that was transporting a dump bed from one of these trucks. It was going from Kennecott Copper to a Cat dealer for refurbishing. It took up all three northbound lanes of a six lane highway. Followed it for about 10 blocks before I went another route. A week later, I ended up behind it heading back to the mine, all shiny and new. I'm not sure, but the pics posted above look like the open pit mine at Kennecott on the mountains west of SLC.

A buddy of mine used to work at a machine shop in our area. They do big CAT parts, including frames for these things and the big loaders. He ran a boring mill so large that they'd drive a semi right onto the table to load/unload. I drive by there every now and then, it's fun to play "guess what part that is" when you see the nice shiny yellow things on the trucks in the parking lot.

Cool to see the manual, thanks SP!

On the electric drive models, komatsu 300 ton units, I have
crawled into the axle housing, (where the electric motor goes)
sat upright, and dug out a broken tap overhead.

I'am 6'3" and was around 325 lbs at the time.

110 gallons of engine oil isn't much, try 8 55 gallon drums
in our other products...

One of our regional service engineers came and gave a talk,
he covered the booganville mine (australia I believe).

He said it was like driving your house.

My friend that works for Cat, the source for the pictures, said they completely rebuild a lot of this equipment two, three, four times. Parts business is strong. Also referred to a company that operates 143 D11s, a piece that cost $5m a pop, and they only make somethng like 10 a year. I think the trucks are $3m a copy. Much of this big stuff is sold out for several years. Because of the crazy market recently they are beginning to require 15% deposit on some of the special stuff to weed out the folks having problems. He hasn't been able to find out what the pictures are or come from. Some of these operations are just incredible.
