Kenworth is made by Paccar in Australia under license. The factory is in Bayswater Victoria. They use the Bayswater factory to manufacture Kenworth’s for all of Asia, including Japan. They manufacture around 18 trucks per day and every truck that is manufactured by Kenworth Australia is a blank canvas custom for whatever the buyer needs.

Having driven around Australia a lot it can be scary overtaking road trains but they will always let you know when it’s safe to overtake them,I have such respect for them

I had two mates who did a motorcycle trip through the Northern Territory. At dusk, heaps of kangaroo would start moving about. After dodging a few roos with near misses, one of my mates got the bright idea of sitting right behind a roadtrain to act as a giant bullbar. Half an hour later they decided that was a very bad idea. Instead of live kangaroo bounding in front of them, they had dead kangaroo being spat at them from under the back of the roadtrain. 😂

I'm a retired trucky in Australia first drove a truck at the age of 16 now 70 years old have seen a great advances in the trucking industry. In the early years life as a truck driver was a bloody hard and lonely life. I have done most of what you have shown there. One thing I can say is every day was different and adventures and sometimes fun

Yes your right Kenworth trucks are an American brand but are made in Australia so are Mack trucks and Volvo

AS a Northern Territorian of Aus who travels the Stuart highway regularly we pass at least 10 Road trains going the same direction between Darwin and NT SA boarder and it is lucky the Northern Territory has a 130 kph speed limit on the major highways whilst road trains are limited to 100 kph. Still stand in awe of the drivers who manage to avoid the idiots whose risks outweigh the benefit

Yes the 509 is a Australian made and designed in Australia for Australian terrain The cab is seperate from the sleeper because of our rough outback roads if it was all one piece like the 909 they would crack and pretty much fall apart And we have the T series over here the T400-T401-T404-T408-T409-T410-T600-T601-T604-T608-T609-T610-T900-T904-T908-T909 and also the W models the SAR’s so many to mention The C series C500-C501-C508-C509 The sleeper is seperate from the cab

Having these trucks barreling towards you on the highway....,You give them room.

11:23 in the video, there is a misconception. The truck in that clip is not transporting coal; it's carting Manganese ore from the Woodie Woodie mine and delivering it to Port Hedland for export. I worked at Qube and even drove that truck, PM354. Qube has a few variants, but you will likely see Quads and Super Quads now. Quads are configured as BBAB and Super Quads BBBB Depending on the configuration and materials used to construct the trailers, Volvo Super Quads equipped with twin-steer super-singles and 'tri-axle-drive' have a total Gross Weight of 199t and a Nett weight of around 145t that I have seen with Bruce rock trailers and reach a total length of 60 meters. I also drove a Scania twin-steering 'tri-axle-drive' 730r with quad-axle trailers, Grossing 214t, It was a nice truck, but the gearbox isn't designed for that kind of weight at HWY speeds. In my experience, having driven various 'top-tier' prime movers, Volvo trucks stand out to be vastly superior. They offer exceptional comfort, reliable air-conditioning (yes), and robust durability.

When I worked as a Truck detailer, a Peterbilt was a super rare machine to see. Every time we got one we would all get a selfie with it looking all shiny and pretty. So Respect USA from Straya 🤘

My wife and drive a Kenworth K200 Road Train from the assembly yard in Gatton Queensland to the assembly yard in Northam Western Australia. We are a 2up team and we drive about 9,000km per week. 51 hours one way.

G'day mates, Australia here. As a frequent driver in the Aussie Outback, here's some info. Remember that Australia is the size of the continental USA, with 1/12th the population, and most of that is around the edges. The Centre is big, dry, and EMPTY. Fuel is often 600km (375 miles) apart, maybe more, so you have to plan ahead, and carry extra fuel, and spare water for a WEEK in case of breakdown - and if that happens, DO NOT LEAVE THE VEHICLE. This is a place that can kill you in a day if you do the wrong things. Many of the roads are dirt - often well graded, but not always. The paved roads often have a single strip of tarmac, unmarked, about 5 metres (16 feet) wide, but with wide shoulders. When you see an oncoming truck, be it a road train or just a B-double or semi (tractor/trailer in Freedomville) it is best to pull well off to the side, and STOP, giving the whole road to the truck, so they can stay on the tarmac. They will usually flash lights or honk to show their appreciation. Sensible outback drivers will always have a UHF radio on the road channel (40) so we can talk to the trucks, and get advice about when it is clear and safe to overtake.

Your right, the Mack’s and kenworths in Australia are designed and built here in Australia

When they say "manufactured" in America what they really mean is a bare essential kit was made in America and sent to Australia, where they are assembled and modified for Australia's ADR ( I used to work at Volvo & Mack in Queensland, a "truck" would just be a big wooden create containing the bare chassis and possibly the cab depending on model )

'Outback Truckers' is a fascinating series with the 1st season back in 2012, transporting community supplies, cattle, houses, electricity switchrooms, farm machinery, yachts, etc in various weather conditions. if you get a chance to watch, some of it will blow your socks off

Ive lived in the outback and driven long haul myself.. if you come up behind a road train and he sees you, which most of the time he will, if he sees there is enough room and is all clear for you, he will usually give you the all clear to overtake by flashing his 'right turn' indicator once..

I’m a bit annoyed they didn’t go more into detail about the dual power train. They are an awsume rig. A company I worked for used to run 5 trailers with the third having its own engine and auto trans. You con see the coolers up on the frame. Between both engines I remember it been over 1100 hp. I only loaded not drove but when I knew one was due you could get out of the cab and feel them coming up the valley long before it arrived.

The dirt is normally red due to the iron content and it stains everything never get it out of vechiles Same with our pink lakes they are very high in salt and a specific bacteria grows in it only if salty enough why not all pink Apparently their OK to swim in we have them in out areas of Adelaide as well and we also mine salt here as well Cheers mate 🦘🇦🇺👍

The Centurion tyre carrier: they were built to eliminate the need to move them with over size permits. It saves a huge amount of time and money, and apparently Centurion themselves came up with the idea. The tyres on board would be for something like a CAT 793. To give you some idea of how big they are, 1. You need to go up a full flight of stairs to get into the cab and 2. They could run over an F-100 as if it were a beer can. The dump trucks on mine sites are often autonomous. To warn people around it, they usually have flashing strobes. For Rio Tinto, that's green strobes. It's safe because it's a controlled environment, the company decides who get to go on the haul road and when. The Mineral Resources autonomous trucks, to the best of my knowledge, there's only two mines they'd likely to be testing, Windarling and Koolyanobbing, iron ore mines out the back of Southern Cross. They have long straight roads between the two mines, and the distance is something like 100 km (not sure of the exact distance. It's been a while since I've been out there)

Hey Ian.. the KW C50- series (50H for short as there are different variants) is Aussie designed and built at Kenworth’s Bayswater plant in Melbourne Australia.. Mack is owned by Volvo and affectionately known as Molvo’s by us truckies as they are available with Volvo drivetrain and assembled in Wacol, Brisbane, Australia.. My old depot (Scott’s of Mt Gambier) was next door and we stored new trucks for them.. Dave

Outback Truckers, have great respect for them. Drove a Hiab crane tray truck in the WA goldfields eleven years ago. Flat tyres a regular on the unsealed roads, and where a bitumen road was a novelty. Shifting mine machinery from one mine to another. Found out the hard way that dust can clog the air breather on the fuel tanks, causing cavitation and loss of power due to starving for fuel! solution was to put a rubber hose from the breather with a petrol fuel filter at the intake end of the hose to filter the incoming air. works well. Blackfella came into the cattle station one day. Had a flat tyre, had a spare, but no tools, got the crane truck out and lifted the front of his car with the crane to change the tyre! Only in the Outback!

My old man, ive taken over the business now. Ran a kenworth k104 B double, cummins signature gen 2. 660hp. His was rated to 56 tonne. Never did a single trip ( Adelaide to Melbourne and back) under 105 tonnes. 1.3million km ( 807782.55 miles) on 1 engine, same box and diff gears. Never used a drop of oil In 30 years he did 6.4 million km. I have the log books to prove it. Which btw is 159.700561 times around the equator. He worked hard for us kids.

I used to go with my late husband to keep him company. The Aussie outback trucker is a race apart, Nicknamed bush mechanics because they break down in the most uninhabitable roads on earth, ,they cant phone for roadside aervice , its down to them.Usually shod in rubber flip flops , filthy ,covered with red outback dust,They change the huge tyres, use ingenuity to solve problems, the are invariably cheerful and put getting their freght to waiting clients before anything else. They are life line for outback farmers, bringing feed in time of droughts and fuel to keep farm machinery running.They are 'characters ',usually looking on the bright side and wirh great senses of humour .They are unsung heros of keeping the outback fumctioning . Not forgetting their 4 legged companions who travel with them ! The good old faithful dogs peering out of windscreens , a two way love affair between truckie and his best mate, his dog !

Largest load I saw was not actually a road train but a premade steel structure heading for a coal mine, took up the full width of the road with special dollys. Was hauled by two massive prime movers connected in line by a steel bar. Was travelling at about fast walking speed. The most impressive sight and sound was the quad magnetite and copper concentrate road trains coming in and out of Ernest Henry Mine in the quiet night time, lights running full length either side 🔥

I've seen those tyre's on a standard flat tray trailer, they don't stack them 2 tyres horizontal 1 forward 1 aft on the trailer and they need a wide load permit and escort vehicles, so that speciality trailer that lets them haul 4 tyres per trailer is probably a big time/money saver. I live near the Brisbane port so I see fully loaded B doubles all the time, but when we have visitors from overseas they are always amazed by them.

Kenworths, Macks, Peterbuilts, ect are built here in Australia for Australian conditions and would be a totally different beast to their American counterparts.

You should see these trucks when hauling mining machines, sometimes they will hook up multiple prime movers, with have two at the front and one or two at the back. And yeah we have a good mix of long nose, and cab over trucks here is Oz. If you get a chance watch a tv series called Outback Truckers, you get to see some interesting things in that show. 😊 The one big issue with AI trucks, is when a tire blows or something goes wrong mechanically, having to wait for someone to drive out too fix it.

West Australian truck driver here. The autonomous trucks are so far only used on private mining haul roads. Steered by people behind a computer screen from perth. Think one guy can operate several of them. Private mining roads can be hundreds of kms long

These are the best Trucks in the world and some of the best Operators in the world. I live with them. Come and experience the roads in this country. You won't leave 🇦🇺👍🏻🍻

Howdyyawl from the land down under. Bloodoath, we've got alot of big toys in the land of OZ. Gotta remember, the operation pf these trucks is all done by one driver. Alot of wheels, alot of responsibility. Gotta give them alota respect😊

Talking about that haulpak truck tyres trailer. “How much do haul truck tires cost? between $38,000 and $50,000 each OTR tires are used for mining vehicles such as haul trucks, wheel loaders, backhoes, graders, and trenchers. These new tires cost between $38,000 and $50,000 each, depending on multiple factors including oil prices and the cyclical nature of the industry.” What’s the value of the load on that trailer? 🤷‍♂️😳😳😂

BTW there’s a firm making trailers for these semis in Oz with rear steering triple boggies, in which as well as each rear triple bogie steering, each seperate wheel in those boggies individually steers as well. It makes manoeuvring in yards much tighter meaning less point turns required. A big difference when it comes to towing multiple trailers.

I drive a Volvo FH16 XXL. It’s a road train built in Australia for Australia. I normally haul two trailers between Sydney & Brisbane

A lot of autonomous trucks are follow-me. Driver in first road train then two follow-me road trains. Used on closed roads to public. Some of truck makers import models a, b & c while building and exporting models x, y and z, thus matching imports and exports to keep shipping cost down.

There is a TV show called outback truckers mostly based on road train haulers

Over the last month I've driven across Australia (not for the first time) covering over 11000km and passed loads of trucks of all sizes. Passing isn't that hard most of the time, especially in the west where the roads are more open with long straits.

There is a video you must check out by Road train Adventures called “This is how you use a ‘stiff bar”, a spectacular convoy of Road Trains crossing a sandy river crossing , I have travelled throughout the Outback all my life and never have seen such a sight, well worth a look at!

The autonomous road trains will be used to haul iron ore on a dedicated (non-public) haul road to the port of Onslow from an MRL mine site

I work at the kenworth plant down in Melbourne building the big bastards, we pump out just over 20 kenworths a day including a couple of DAF cab overs. Plenty of the big mining trucks come through which are huge in person compared to the normal kenworths. There’s a new DAF coming through soon which is an Aussie only model using a 15L Cummins motor, such a cool truck

You are totally right 😊 truckers make the world go round. They are the ones who supply us everything, every day and we would be lost without them ❤❤❤❤ unappreciated heroes ☺️ love you guys and girls getting us what we need all year round. So much love ❤️

Just a thought when I see a road train coming towards me I try and stop and get off the road, the amount of stone etc that can be thrown up on bad sections of road it’s not worth taking the risk of broken windshield and dented body work, did you notice the huge Bull Bars as well it’s not that they don’t want to stop it’s just a case of not being able to stop in a short distance think about it 200tons if they lock all the wheels up 36 of them (please correct me I’m incorrect) it’s a lot of money to replace all the blow outs, so the cattle/ roos/ camels ect just get ran over, it’s good for the wedge tail eagles lots of roads kill

I actually drive a road train for Russell's Transport sub contracting to mineral resources, the truck I drive is a 1997 mack titian with a C15 550 hp cat engine coupled with a 18 speed road ranger gear box capable of a total weight of 140 tonne and measuring at 53.5 metres long in western Australia we can spend 15 hours a day behind the wheel. It's a hard life and not for the faint hearted. If you are in western Australia some time you should try and visit some of the transport companies to take a ride

I love your enthusiasm. You make watching things I seen before exciting again.

You should check out the Convoy for Kids held every November in Brisbane Queensland. Last year over 700 trucks took part in a fund raising event for children's charity's. The Convoy travels across Brisbane ending in a show ground affair, where you can get up close and personal with the trucks. A great event, great trucks, and great people.

Some Macks are Built in aussie

Love when youre on a long drive and the truckies let you sit infront of their tailwind, saves so much fuel lol I work in port hedland in WA and we get the 60 metre long trucks through pretty often, they're actually kinda scary

I think the autonomous truck operates on closed private roads for very large iron ore operations. A closed road simplifies things massively and is a good application. Most acurately it would have traded train driver jobs for operations supervision. I'd really like to know what made it worth doing - just the driver remuneration and expenses? The mass (did it say 375 tonnes?) is amazing.

It’s been a while since I’ve been on your channel mate and I have to say I love the new atmosphere your posters behind you are my childhood and now my garage walls

We call the properties Cattle Stations. and they are big compared towhat you have in the US. Aslso most road trains run 18 speed tansmissions and can be aither auto or manual tansmission. Cheers.

the big tyres can be transported and are horizonal 2 high on a standard traitors and 3 high on a lowloader but they are over width and require escorts/pilot in some places and police escorts in some cases but this way their not overwidth and can travel without all that permitting and extra cost of other vehicles.

The main reason why trucking companies choose to have the Kenworth K200 cabover is to be able to have longer trailers as some state have laws on lengths.

I’m an old truck driver and yes American trucks were imported into Australia, but the import tax was 80% so they carried on the name and imported parts at a cost of 8% hence building the trucks in Australia made them more affordable, European trucks are now more powerful and cost effective with real comfort.

Those tyres are worth 30 grand each. They’re stored down in Perth and they have a spare tyre for each one in operation up north. They’re made to fit the Haulpaks on the mines. When there is a puncture the trucking company has 48hrs to get the spare tyre up to site.

One of the things I found surprising when I first traveled overseas is how heavy machinery in other countries appeared like children's toys to me after growing up in W.Aus and regularly seeing our heavy machinery/trucks growing up.

I work fir Penske here in Nth QLD - Western star trucks and detroit engines are our babies. Big babies and we love them

Australian Made “Every Mack truck you see on the roads in Australia has been made in the western corridor of Brisbane and these Australian engineered and built trucks continue to deliver application excellence for our customers......

3:50 the narrator of that video; "Pilahbra"... it's Pilbara, pronounced "pill-burra"! Didn't even read copy properly. I'm just glad you didn't say it too.

As someone who works in the pilbara region of the northwest of Western Australia working on the "on highway" trucks, you should look into more of the iron ore and lithium ore movements up there. There are fleets up there as MGM, Dave Campbell transport, Jamieson transport, ReGroup, Bulk Line, Qube. Running Kenworth C509, T909, Western star, Mack, Scania, Volvo. The combination of different quaf road trains from "quad" to "mega quad" and "super quad" configurations up to 240T There was a company that were running "quince" set ups of 5 trailers, but still within the 60m limit as well. No to mention the movement of bulk liquids, and also other mining production products. I really feel you would be amazed at the scope of the operations in the region and how they all work

My husaband works in an open cut mine in northern Western Australia and they have autonomous dump trucks over there. My husband says the first time you see a huge driver less dumpy is pretty daunting.

Theres a company in Perth that retreads those Haulpack tires

In Australia we have length restrictions. This also can include axle spacing. This is why cab overs’ are a little more versatile. In Oz the restrictions are really tight. We also have, in a few cases, moving oversize loads, a tri-axle rig. Mack had the first one of these out. (Ex Macalease Company truck, now centurion) we have some incredible trailer modules and platforms also. Google that stuff. In Oz we have a bit of open space.. the outback. That is just the tip of the iceburg. Google oversize loads in Australia. Dump trucks- just the chassis over here can be anywhere up to 360 ton enjoy ❤️👍🦋

For the last few years the truckers like to decorate their trucks with lights and it like they all decided to be lit up like various Christmas trees, it’s quite an effect to when driving after dark

On the wall behind you, above the TimTam add you have a picture of a Torana in he colour 'Orchid'. When I wrecked my SLR5000 😞 (the silver grey one just below the Calais sign) I bought one just like that in that colour - 3.3lt straight 6.

ALL Kenworths are manufactured at the plant in Bayswater Victoria. My husband used to make the wire harnesses for them.

The triples were I think 53 metres long and caused accidents because overseas visitors couldn’t judge the distance for overtaking.

IVE ALWAYS LOVED SCANIA ever since i was a kid !

Volvo/Mack trucks are assembled/manufactured in Wacol, Brisbane. I can smell the paint fumes when the wind blows down stream. Not that I'm complaining, i live next to an industrial area, so i expect that.

large mining truck tyres are sometimes hauled on their side and stacked. in such conditions they are considered wide loads and have a leading and trailing car warning other drivers so they can pull over. As a Western Australian i have encountered them before.

Triple (three-trailer) road trains operate in *western New South Wales, western Queensland, South Australia, Western Australia and the Northern Territory,* with the last three states also allowing AB-quads (B double with two additional trailers coupled behind).

I’ve been camping out in deep nt beside roadhouses and when a full train goes past it’s like being next to a cyclone going past

Can’t wait to see that autonomous tire change 😂

I use to work at the centurion track yard in Perth and those trailers that came in were massive

there is an iconic photo somewhere i saw at a Pub here in Aus that show a massive road train going threw one of our citys.. im talkin like 30 trailers weaving threw the streets. u must see and find this picture..

I've lived and worked in the Pilbara and in Darwin and QLD, and that red dirt stains your ute pretty bad. Takes a lot of work to get it out.

5:45 we *need* those tires on Monster Trucks

I worked on in the iron ore mining industry for many years. The end of my working life was spent east of Port Hedland in an exploration camp. Saw plenty of the quads and super quads. What amazed me was the number of tyres on the road. The most I saw was a super quad with 144 tyres. Yes the drivers always looked out for those wanting to pass but of course you had to have a CB radio on channel 40 to communicate with them. Typically they would say something like “LV following TM353, which might be the truck’s ID number always on a sign on the last trailer, you’ll be clear to pass when………..vehicle passes”. I also saw many of the haul truck tyres delivered to the mines I worked on over the years. They don’t carry them laying on their side because they are approx 3.6m, nearly 12’ in diameter. Oh and 10 years ago they cost nearly AU$40,000.00 each. A haul truck suffered a blowout about 120 m away from where I was working and spat a piece of rubber in my direction. The sound of the blowout sounded like a blast in the pit and rattled doors and windows 300 m away. I looked up to see what the noise was and saw this object heading in my direction. I ducted behind some equipment I was inspecting. The piece of rubber struck an IBC directly behind me and shunted it about 1.5m across the ground. If I hadn’t ducked it would have taken my head off.

There is a show called "Outback Truckers", not sure if you have seen it, but I'm sure you would enjoy it. Moving all the mining equipment to the mine sites. How the other trucks get bogged in the outback in the wet season..

Yes i have been to the Kenworth factory in Kilsyth Victoria. Where i saw the trucks being made it was very cool.

Minres autonomous trucks have their own road fom mine to port of onslow in western and run in groups of 5 roadtrains,they have safety drivers in there for testing

The majority of Australian Macks are built in the assembly plant at Wacol in Brisbane, they share a roof with Volvo they used to build Renault trucks as well at the original Richlands assembly plant (no longer operating) but i believe Renault are owned by Ateco now. I worked in the Mack national parts at Richlands back in the late 90's until they moved to Wacol, but our warehouse was relocated to Minto in Sydney at the time. As for autonomous vehicles, i believe we will eventually see more of them doing the heavy mining and long haul operations, and current drivers doing changeovers and local deliveries. I believe the reason we have so many trucks in Australia relates to the apparent lack of infastructure to support other transporting methods such as rail and so forth.

- Kenworths are built in Australia (we don't have Peterbuilt over here - at least not common/ late models ). for the local market - PACCAR owns : Kenworth, Peterbuilt, DAF, Leyland Trucks - - especially American style "gumboot" prime movers trucks can be bought optioned from a range (or whatever the operator wants) engine and gearbox selection (Mack is the Australian Volvo option in a long nore config). Western Stars are imported from the USA. I recently drove with a buddy from Port Hedland - Northwest WA to the East coast of Australia.. Lots of Roadtrains - in the Northwest the 4 trailer "super quad roadtrains" (A-Quads) are everywhere in iron ore country, across to Queensland a whole range of 2, 3-4 [B-double (as commonly seen as regular semis elsewhere), A-Double, B-triple, AB Triple (B-Double on an A-dolly behind a Semitrailer), A-Triple, BAB Quad (2 B-doubles in a train) , ABB Quad (a B-triple behind a Semitrailer) ]- huge variety trailer configurations and load outs seen. Volvo and Scanias are operated by those who want to brag about their "European quality" - not to diminish the technology, but even the American trucks are getting hybrid driver monitoring / assistance packages with "autonimous features" - just like agricultural tractors, don't forget the scandi trucks are built for summer logging in Sweden and Finland - those conditions are not easy - - vs the Easy to work on, highly customisable long nose Kenworths (Melb), Macks (Brisb), Western Star.(Portland USA).. (For a fairly tough haul unit: look at the Kenworth C510 - "off highway" - payload 300 tonnes with the use of an additional power trailer- in the train. - some reports indicate engine specs up to 1000HP ?? I don't doubt if one is ok with reduced reliability several multiples of that are possible - ) - lol, on private haul roads there basically is no limit - to the limit of the logistics itself - add several power trailers and dolly couple 4 B-Doubles if that fits one's operational requirements.

6:56 and it's not just about just the transport, but also loading and unloading, because think about it. They could just use regular trailers and ship them horizontal... but that would damage the tire's face before use, and more importantly, it would add two extra steps to the affair on both loading and unloading - as you'd have to tip the tire. This is akin to US' car trains where they'd put cars vertical to ship them by train, but in reverse, they built those cars specifically with the idea of putting them vertical and they made the special train cars to pack as many cars as possible in one load.

One of our primemovers is an International Eagle which is US built. We have heating problems because the radiator fins are too close together for hot Australian conditions

The C series Kenworths are all designed and built in Bayswater (Melbourne Australia) from the C500 to C509 510

My auntie actually is in charge of maintaining some of the massive autonomous dump trucks in a mine up the north of Western Australia.

Before speed cameras and GPS tracking some trucks use to travel fast speeds around 150 or 160klmph ( 100 mph)they almost blew ya doors off.

Those massive tyre trucks come passed my house daily (in the city) but they can only tow 2 trailers/16 tyres. Out of town they add more trailers, but yeah, even from my second floor, they're big!

As a Truck Driver in Up North Western Australia, I Drive for QUBE and operating thier Macks,Volvos and Kenworths all in Super Quad combinations, i can Confirm MRL are currently running thier autonomous trucks, they are not running them on public roadways as of yet.. only on Mining leases.

All these vehicles are awesome. They do a great job of hauling a huge payload from point A to point B. The operators do a great job too, they are the REAL heroes. BUT ALSO, heroes come in all shapes and sizes, especially in the trucking industry. Even a 20 metre long semi takes skill to do a blindside reverse up a slippery uphill grade change in a tight spot. Shout-out to all the operators who drive supermarket trucks, some of those docks aren't for the faint hearted lol

That Bis truck had a power pack second trailer, that is a second engine that powers the wheels on the trailer and helps with the load. Most dump trailers run on hydraulics off the trucks engine for the lifting and compressed air for unlocking tailgates, single dump trailers are dumb, that is just hoses connected to the lifting / locking pistons and valves in the truck cab control everything, but multiple trailers can have electronic solenoids to control their functions with the truck just supplying the hydraulic power and air pressure. Some trailers also have their own engines for hydraulic functions, which may be remote controlled, but they are normally trailers like lowboys where the hydraulic power is only needed to configure the trailer for loading / unloading.

An uncle of mine is a quarry works operations and equipment specialist and emigrated out to Oz about 20 years ago. He travels the length and breadth of Australia inspecting and consulting at quarries. He flies as far as he can usually, but has had to spend days driving something like a Toyota Landcrusier on the red dirt roads used by road trains. He's sent me some crazy cool photos of where he's pulled over to allow road trains to pass. I kinda miss quarry work now watching and thinking about it all. Let's just say I used to get through some of those tyres.

Kenworth manufacturing plant - 64 Canterbury Rd, Bayswater VIC 3153 Mack Trucks - 41 Bivouac Pl, Wacol QLD 40 Volvo Truck Production Australia - 36 Viking Dr, Wacol QLD 4076

We also have a truck called a Kenworth C510. It's ofroad only as it is about a ton and a half heavy on the steer. We pulled 225t in 3 trailers at about 85kph.

Fyi, i work in the mining industry here in western australia, and can tell you the mining company with automated trains (rio tinto) also has automated mining dump trucks. At this point they have more automated trucks, then driver driven trucks.

The super Liner and C509 are made here in Australia. Kenworth, Mack and Volvo all have factories in Australia

I Lived in the Pilbara region where a version of these trucks are in great numbers, during my time there I was a Volunteer Fire Fighter and can tell you when they catch fire , crash or tip over it is always a long day in the heat.

Kenworth trucks are made in Bayswater, a suburb of Melbourne.

Yep Built in Australia.. My brother works for Mack / Volvo trucks in Brisbane… they also build custom and export to overseas..

With regards to the Centurion tyre combo, you can stack those tyres and travel as an oversized load; but you can only stack them two high, and the oversized loads are much shorter so you can’t carry as many tyres or take as many trailers. So on a normal flatbed trailer, you might get four of those big tyres, but you can only take one trailer; and you would need at least one specialised oversized pilot to escort the load because it would be so wide, other traffic would need to be cleared as the load travels. Have those same tyres standing up on the specialised trailers, and you can get 6 tyres per trailer, pull 3 trailers with each truck, and you don’t need any additional escorts because the entire combination is within legal limits. Centurion actually designed and built those trailers, and other companies are starting to use the same idea to maximise tyre transport.

At 1.40 minutes mark thats a tri drive mack titan, day cab they mainly used in mines or for bulk hualage of fuel, thays when you hook up a quadie (4 trailers down the Tanimi highway)
