- Lots of people, especially overseas friends, love Aussie roadtrains and they're always asking what it's actually like to drive one, so I've put together this clip to show people what happens. This is a Mack prime mover, with a Cummins engine and 18sp Mack gearbox. The roadtrain has four trailers (a Quad) and is 150' long (53.5 metres). Empty, it weighs, 65 tonne and laoded, 150 tonne. It's speed-limited to 90km/h.

Just read your story in the Guardian newspaper today.
Inspiring stuff to not be afraid to just say:
‘Fu@k it, I’m going to do this now instead. Decision made’
Great stuff !
hahaha, me too, from CEO to truck driver amazing.
G'day Pete, my friend, if my little tale inspires you, just go for it. There aren't enough years left to sit and wonder. I reached the conclusion that if whatever you want to do doesn't harm yourself, or anybody else, then it's all good. It was a great self-learning curve to be the new kid on the block, with people a lot younger with much to teach me. All I can suggest, is steady, steady is the way to go. In many ways, driving a roadtrain is like a combination of piloting a boat and riding a motorbike.
This guy is extremely good on camera, should definitely make videos more often!
I grew up in a small country town, sitting bored in a school room listening to trucks leaving town onto the highway going up through their gears - rrrrmmm, pause, rrmmm, pause, rrmmm, pause, etc., etc. - I wanted to be a truck driver, to get the hell outta that boring town - my friends who were truck drivers were always saying they'd just come back from Bullamakanka or some far-away place - I dreamed to go there too.
Great vid larrikin ! Keep them coming, stay safe up there - have good run cobber.
Wow your wagon is the same weight as a Boeing 707 Airliner, the quad is one of the coolest road trains, there are 5 trailer trains with a second booster engine ,usually on the third or fourth trailer and the Bulldog is my all time fav lorry maker.
G'day Basil - I used to drive the five trailer twin engine roadtrains and did a video on them - Give Me Forty Acres and I'll Turn This Mother Round, cheers.
@@TheElegantLarrikin.The Bulldog working very hard up that steep hill, no wonder you skip changed down the box, really needed that second booster engine. Regarding pony count, cannot beat a 19 litre Cummins QRSK 750-900 ponies, but due to AU,s strict laws on exhaust emissions in which the QRSK does not comply. most roadtrain tractor units are fitted with the smaller Cummins Signature, 15 litres around 600-650 ponies, okay for triples but marginal on quads, especially on arduous tipper work on loose surface dirt tracks. Bulldog,s Jacobs engine compression brake works off the valve gear, altering the timing to turn the engine into a compressor, hence the distinctive bark when engaged,. Are you carrying crushed gold bearing ore which is denser than coal?, as the trailer axles are closely spaced .
WOW Hello TheElegant Larrikin TELL ME MORE !!! as I am an addicted to road trains, a bit of a handful but soo cool, especially the side tippers working out of the mines at Alice Springs. regarding the Bulldogs Maxitorque gearbox , is it a 15 speed with an extra splitter function, as the gear gate diagram in the Bulldog,s cab shows a 5 speed main box ,also unusual is the tridrive rear bogie with Macks own double reduction spiral bevel spur axles. Later Bulldogs are fitted with Finnish made SISU hub reduction axles with cooling fins cast into the reduction hub casings ,like a motorbike engine cylinder barrel. Stability wise the 'B' train is better tracking, as each trailer coupled to its mate via a 5th wheel over the bogie, doing away with the drawbar dolly forecarriage. But in life there is no such thing as a free lunch, ten fifteen percent off the price. Compared to an 'A' train ,a 'B' carries slightly less payload, but a tipper operation where max payload is prioritised, the quad 'A' like yours is a no brainer . On the upside an ,A, train due to its dolly forecarriages has a lower axle load . Is it possible to run a roadtrain on super single tyres instead of twins on each trailer axle ?, I like to know, Thanks.
Hi Xantex, yes, it's a crash box. Some people use the clutch, but I'm one of those who prefers not to - I mean, you use the clutch to start and stop, but not to go through the gears. It is very much a case of matching engine and gearbox speeds, as a rough guide, it's usually in steps (up or down) of 250rpm, it depends on the engine etc, but you're usually working in a rev range between 1,500rpm and 1,750rpm, coming down through the gears, you'll just blip the throttle to bring the revs up cheers
drove 2009 mack trident tri-drive tractor unit towing 6axle Btrain or Semi Quad back in NZ which i named Big Mack Combo..should have taken more pix an vids of ...
All outback truck drivers rock on
god! takes half a mile to slow it down and a coupel of acres to turn it around. Don't miss your turn!
Loved the video mate.
Is there any chance you can upload a video of Maggies jumper without your narrative.
Your narrative was terrific but Id love to hear that mack sing working its way up and then down.
Yep I'd love that
thanks larrikin
how did you get onto driving quads?
Is it fun to drive a big quad side tip road train like that
Amazing that this guy obviously relies on his MDL for living but is happy to film himself breaking the law and publishing it.
How difficult would it be for me in america to transfer over to driving road trains in australia
Hi mate (Brisbane) great video. How much fuel do you use? Liters per klm? LOL
That's funny. Here in the states, a prime mover is the deisel engine in a locomotive.
That's one hell of a prime mover!
Dictionary definition: means of towing a cannon, as an animal, truck, or tractor.
at least you don't call them 'lorries'
Hey, Mate! i lile your accent!
you`re funny when you speak... what was the place you live?
Do you get paid well to drive a Super Quad ?
Just wondering why if you stalled it would you need a tow truck?, Is it because a hill start the truck wont have enough power to start off from 1st gear again?
It's not so much the lack of power, but lack of traction. Those 12 driving tyres simply cannot pull so much weight from a stand still.
@@MrGranto Thanks mate. That was an awesome video, Thanks for the reply Gee-rant Smith.
Just out of curiosity and being from the States, how many hours are you legally allowed to drive?
+Vic Reece depends which state
BFM in eastern states will allow you to go 14hours
Fatigue management in WA will let you go 17 hours with a 7 hour break for 2 days then 14 with 10
the gearbox in that mack, is it by any chance a "crash" gearbox where YOU match the engine speed and gearbox speeds, requiring a double-clutch technique when gear shifting.?
Pretty sure MACK have their own type of gear box it's called an mDrive I believe.
this video gave me a squishy feeling🌈🌈🌈🌈💉💉💉🐹🐹🐹🐹🔫🔫🔫🎆🎆🎆🎆🐞🐞💚💚💚🍓🍓🍓🍓🍓💜💜💜💜
oh i 'm sorry!
was go to say: i Like your accent!
I'm going MAYBE to Broome yeee!
bloody gravitate
i am interesting joining trucking need helper jobs ..
This looks just ... O SO BORING. 12 years of this would drive me into an insane asylum. (No pun intended.)
I see your point, but it actually isn't. I'm fact up in the Kimberly and Pilbara regions, although there are long boring stretches, there are also stunningly beautiful areas, plus of course, you do tend to change jobs - mining is very much about the money and also management - if your supervisor is an agro, know-all arrogant prick, you move on. So you work different minesite and different roads. Some jobs, you drive on a minesite haul road and then some short hauls can be a bit same same boring, other jobs, you drive on public roads. Hope that explains it, cheers
