    So Gavin, Whats the story behind them selling off near new iron?

    Is Moolarben a contractor? If so, it seems odd they would buy the gear, run a while, then sell the gear at what would almost have to be a huge loss in the current market, and hire the work out.

    Any ideas?

    Think you got a little confuzzled there, Mt.Keith and Moolarben are two seperate mines. Mt.Keith are selling the 8000's and slashing jobs to help ensure the economic viability of the mine due to the nickel prices slumping in the economic downturn.

    Moolarben is just the name given to the coal deposit, the mine is run and owned by Felix Resources Limited.

    Chris nailed it pretty much there Jerry, Mt Keith is a BHP property and mines nickel, they had a 50 strong fleet of 793 trucks there, biggest fleet of 93,s in Australia and with the GFC nickel went down the gurgler. Was an alliance contract whereby BHP owned the majority of the gear and Theiss Contractors ran it, changed back to owner mining in Feb this year and then the downturn really hurt them, but not nearly as much as there brand new nickel mine Ravensthorpe in southern West Australia. This mine just came on line about 12 months prior to the GFC and had budget over runs for construction by 100,s of millions and when the GFC hit they mothballed it!! Total cons cost was somewhere in the order of $2 billion i think.

    Now Felix will do well at Moolarben, they can free dig pretty much to the very thick coal seam they have, they have purchased a predominately Komatsu fleet and have chosen Liebherr excavators, the Komatsu order is being touted as the single biggest order in Australian history for them and i have heard somewhere in the value of $250 million!!

    Chris, Gavin

    Thanks. That clears it up.
    Some of the big mining companies have really took some losses in this mess. Hope they can weather the storm.

    Someone will probably get a good deal on those 8000's

    I'll get some footage of the 996's once their up and running and loading trucks, I'll have to be sneaky though, their very stringent on the use of camera's. I'll try and get some in-cab views too.

    I saw more 830e trucks be that AC or DC running about than any other truck during my quick visit to the Sydney coal basin (the mines around Mudgee and in the Hunter are part of the same coal basin).

    Also saw T282, CAT 793C / D poweredge, CAT 789C, Hitachi EH5000, 930E and others.

    These 2 996 at Moolarben along with the 4th at Mt A are the last few of the 996 run as you see them here.

    I've had a bit to do with liebherrs (994B's - 1 less engine and 300 tonne lighter but the principles the same!) and have found the worst part to keeping them going is getting someone to understand the electrics, once you get your head around the electrohydraulics they're fairly reliable and a reasonably nice thing to work on, the cummins engines have been a letdown for us (QSK45) they have proven to be a good candidate for block ventilation, and never anywhere convenient! (Have heard liebherr are trialling MTU's - if they prove as reliable as the one in our EX3600 they'll be perfect!) But yeah if they get some loving by blokes who know they're stuff they'll be a good thing!
    As for the Komatsu's, never had much to do with them, I hear the trucks are fairly reliable, but how do there ancillary gear go, dozers/graders etc? I'm fairly CAT bred but am curious to know how other gear stands up to the challenge... I dunno if they have loaders but after seeing the WA1200's at CVO & Goonyella they are a good thing if you can keep engines in them (Cummins again....)

    The key issue with the cummins is down to hp per litre. They screw every last hp out of each litre and if the care and air is not the best, then it does not take long to kill it.
    One of the reasons why the 830e is reliable is that is has some in reserve. QSK60 with 2500hp = 42hp per litre. The same lump in the 930e is tuned up to 2700hp = 45hp oer litre and technically it can go up to 2850 or 47.5hp per litre. The QSK78 is tuned to 3500hp or 45hp per litre. Compare that to the CAT 3516, which is also 78 litres, but is only tuned to 2415hp in the 793D or a mere 31hp per litre. Ditto with the 3524 which is a staggering 117 litres for its 3550hp.

    On the flip side, it is also why the cummins is less thirsty than the CAT. It's just where the balance point lies.

    Mr Fowler,

    I found your Thread very interesting except we talk HP per Pot.

    793B (2100 HP) 130 HP a Pot.
    793C with HD Conversion sit at about 145 HP per Pot.
    793D 150 HP per Pot.

    Then we toss in Duty Cycle and Fuel Burn.

    A 3516A (with electronic Option EUI) in a PC-8000 only makes 120 HP a Pot but the Duty Cycle is up aroung 80 to 90% so PCR drops down to around 11000 Hours. LOW Output but high Duty Cycle.

    A 3516C in a D Truck is screwed up to around 2400 HP and PCR is 2 660 000 Litres of "Motion Lotion" and Duty Cycle is barely 50% so PCR falls around 13000 Hours.

    Can some one in the Know compare these figres to the Cummins for friendly comparison??

    QSK 60 Fuel burn LPH
    Fuel Burn till PCR
    HP per Pot..............???

    The QSK60 is a V16 so
    @2500hp = 156hp per cylinder
    @2700hp = 169hp per cylinder
    @2850hp = 178hp per cylinder

    The QSK78 is a V18 so
    @3500hp = 194hp per cylinder

    I have some fuel burn figures somewhere..............

    I think the C175 are due to arrive in Oz later this year. There are some interesting stats on these too.

    C175-16 in the 793F is rated at 2650hp, is a 16 cylinder displacing 85 litres, so 166hp per cylinder or 31hp per litre just like its predecessor the 3516 in the 793D.

    However, the fun starts with the 795F, which also uses the C175-16, but rated at a staggering 3400hp or 212.5hp per cylinder and 40hp per litre! The latter is in the same territory as either of the cummins, but the former outstrips the QSK78 which has two more cylinders (18) to deliver its 3500hp.

    Finally the C175-20 in the 797F is 106 litres out of 20 cylinders, so the 4000hp is at 200hp per cylinder or 38hp per litre.

    So interesting times ahead!

    Rod, don't quote me on this, but from memory, the QSK60's in the 1200's at Cadia sit around 1800 horsepower (112.5hp per pot) and burn approximately 250 to 260 litres per hour with a duty cycle of 60 to 70%. Fuel burned until PCR is 4,160,000 litres (@ 16,000 hours) and believe it or not Bulga's did reach this! I don't consider this statement to be entirely accurate as it is only from memory but for the purpose of rough compariosn and to satisfy your curosity, it will do!

    The PC8000-6 has two Komatsu SDA16V160's (QSK60's) and they run at 2000 horsepower each (125hp per pot). I would imagine the duty cycle's would resemble that of the dash 1 at Cadia and it would be interesting to see the fuel burn and PCR. I'll do a some research and get back to you with some facts.
