These Massive 1000 horsepower Kenworth C510s at Burton Downs Mine are specifically designed for off-highway use and rated up to 250 tonne. They’re powered by Cummins’ 19-litre QSK-19 engine which complies with Australian on-highway emission requirements (ADR80). Designed primarily for high-end road train applications, the big-bore Cummins engine provides superior levels of durability and reliability than is currently available from smaller cubic capacity engines.

The engine delivers 606 hp (447 kW) at 2100 rpm, with peak torque of 1950 lb ft (2644 Nm) at 1300 rpm. Other key components include an 18-speed Fuller RTLO-22918B transmission, with a first gear ratio of 14.4:1 through to 0.73:1 in overdrive. Rear axles are Axle Tech STRC-1297 hub reduction (they’re the old Rockwell off-road model) with a final ratio of 9.59:1. The front axle is Rockwell FL941 rated at 9.1 tonne and the 295 mm deep chassis which has a far thicker web and flange than its highway cousins and features a full length double frame.

These power trailer units have a Smith built body on the power-trans chassis (they’re the company who built the power trailer unit) and they’re fitted with either Cummins ISX or Signature engines rated at 450 and 500 horsepower. They are coupled to an Allison automatic transmission and tri-drive SISU hub reduction axles.

The control of these trailers is via both a cab mounted hand throttle and married to the accelerator pedal. The advantage of this for instance is when the unit is climbing a hill the trailer can be set at full throttle and when the driver changes gear in the Kenworth C510 there is minimal road speed loss as the trailer is still pushing the unit.

It's nice to see a video that gives all the specs on these massive machines, in a concise and non-dramatic manner. After all, that haulage is dramatic enough as it is! :)

The music really needs to be louder - I can almost hear the engine.

I'm a railroad locomotive type of guy but I must say, this is awesome. Trains are flatland creatures but it looks like these machines can handle hills just fine. Often saw three trailer cattle roadtrains going north when I lived in The Alice, but five was from a bygone era, plus they're lighter too, so nothing compared to this machine. Nicely done.

No one else going to acknowledge that insane 9.59 gear ratio in the rear

'Trailers built by Smiths of Gympie'. When I was an electrical apprentice with Noel Andrews in Gympie in 1970 we did Smiths electrical work. Their 'factory' was basically a corrugated iron roof down the side of a hill. We used to joke that if they had flat ground to build a truck body on it'd be crooked. They turned out lovely stuff, they got flooded 2 or 3 times a year and Jimmy Smith was the best bloke you'd ever hope to meet. I was working in Gunpowder about 1975 and GCL was using Smiths side tippers. Great that they've moved on and up.

This mode of coal transport was/has been used at Jellinbah mine near Blackwater for many years. The coal is run from the mine to the loadout near the highway. Dozers push it into the u/g hopper and the coal run up a conveyor over the highway to the hoppers on the rail line.

Imagine pulling in at a service station and say, "Fill `er up, mate. Whilst you at it check my tyres all round, please." Two days later......

Incredible to think that all 98 tyres on this rig cost not much more than one ultra class haul truck tyre but carries near the same payload

We had a R40 Euclid haul truck that had a QSK 19 Cummins in a underground limestone mine. It did quite well.

Worked at that mine before it was shut down a few years ago! Massive trucks!

Very impressive. Did my apprenticeship on Cummins diesels, Rockwell differentials and fuller gearboxes. Must be a challenge to drive with five trailers.

This truck is straight out of mad max

I just finished getting my CDL license today (in Utah, US). I can't even imagine driving one of these, though that would be so cool (with training, of course).

I have driven a 500hp volvo with the ishift through saskatchewan, which has similar terrain to australia and i got to say its honestly the easiest trip i have ever done. Such a lounge chair. If kenworth learned how to make a cockpit, i believe they could be some dream machines.
