    The hydraulic oil tank holds 8350 ltr (2,205 U.S. gal) and the hydraulic system requires a total of 11500 ltr (3,040 U.S. gal).

    It may have changed a bit since the last time you were there but the winter programs still around. I found out Friday we got the contract for 2000+ km of winter road and around 400 leases for core holes. I head up mid November to start brushing for the camp they want to put out in the bush for us. Largest winter program I will have been on.

    K2 is a joint venture between Kiewit and KMC Mining.

    Funny you should ask, we had this very discussion last night. I'll try and get the actual numbers, but I can give a rough idea of what models they have up there right now. I know there is a 5130B, a 5110B, EX1900, PC8000, 793D trucks, 777 trucks of various series, lots of D10T and R dozers, a fleet of 657 scrapers, and so on and so forth.

    Bear in mind, this is not their mining fleet, they are in the early stages of development for the site. There are still a couple years of dirt work and plant construction to do before they start operations.

    Nice pics Chris!
    What's the purpose of the road barrels anyway?
    I assume it's an aid for judging distance or help aiming or whatever but exactly who is using them and for what?

    I think it's a center load aid? Or an aid for the truckdriver to get it lined op the right way?
    I wonder what's your opinion on the right angle of the back of the bucket?
    Alco? Chris?

    Looks good to me what the pc8000 operator is doing when discharging the bucket.

    It looks like those cylinders are leaking. Is this a brand new machine?

    The cones hanging from the bucket cylinders are for the truck drivers to use as a reference when spotting themselves to be loaded. It just makes it easier and faster since they are in the ideal spot for the shovel operator.

    I'm not sure what you are asking about for the bucket angle. If you want to elaborate on what you would like to know, I'd be happy to try and answer for you.

    Yep, it was a brand new machine at the end of last winter. They do appear to be weeping a bit, but nothing worth worrying about yet.

    I think I know what you mean, so here goes...

    If you notice when they go to empty the bucket they dont simply open the clam but instead at the same time retract the bucket cylinders to dump the bucket so it actually appears to "spread" symmetrically.

    Appart from the style of the operator, I can think of only one reason for doing this. Faster cycle times.

    By doing this, once the bucket is empty it is fully curled forward ready to engage into the face for the next bucket.

    Why not do it after you have emptied the bucket?

    Because it would be alot slower, you can only have four functions at once for example clam close, stick in, boom down, slew right - you would have to wait for the clam to close before you could then curl the bucket.

    Hope this answers your question :)
