  1.  @seban678  its not quite a normal clutch, is a special coverting one that can be used as both converter and clutch.

  2. It sould. What is in sweden and finaland just called a truck. A double articulated 25meter long vihicle is in a lot of countries called a road train. Also worth saying that 30 meter (or 32 meter, quite exactly recall) can be transported with a permanent permit. Standard truck weight was recently expanded to 74tons. The only thing you need for 74 tons is a standard truck-trailer license. And they can go pretty much anywhere with in the country (apart from places with special bans of case). And we do that pretty much on a regular service going into central Stockholm with flatpack concrete buldings. Intresting there is no hight restriction what so ever. If it fit under the under pass its fine. If you have a 10 meter high sailing boat and you map your route out not going under any underpass. No problem. Also over size load can be pulled with no permit or simple permit. This is the most common heavt thing on swedish roads. They are generally not very long. Like 18 meter or so. But can be 4 meter wide and typically they try sqezing it in under 4.8 meter in hight do clear most overpasses. This is a strange thing in sweden. Most heavy manufacturing is inland in smal towns that nobody heard of. The reason is hydro power. Because back in the 18 century prior to both electricity and steam was a thing, they had to build all those stuff right nexto waterfalls. So loads of industry grew up nexto inland waterfalls. Untill 1970 most things was just transported on chanells. Then railroad. But then the stuff grew to big to be transported on railroad. So that is the reason we have loads of huge trucks The timer and ore industry have just followed along.

  3.  @Aquarium-Downunder  We sort of don´t use the term in Nordic countries. But the people down on the continent usually call our trucks for road-trains. Of cause, when they go down to Germany they have to split them on two trucks. The thing is that we have mostly double hinged trailers, they are quite a bit longer than the normal single or semi hinged. At least when pulling lumber, the double hinge are exactly double as long as the semis. And semi trucks are quite rare. Most trucks used truck bed with a double hinged trailer, than if its a long truck, there is a semi after the dubble hinged trailer. That would make it 4 lumberstacks long, its the same length as 3 semi trailers.. I did find two videos of nordic trucks that only exist here. Some of them are actually pretty common, some are a bit rarer. https://www.youtube.com/watch?v=wZB-qZj2GBs The first one is probobly just a finish thing, have not seen those here. Second one is really about the lifter, but there are loads of trucks there, looks like there are both 2, 3 and 4 stackers. And nowdays there are high and low stacks also. The high stack fit about 30% more. Third one extreem loads. Those are actually fairly common, even at normal roads. Of cause, loads that big is a bit more uncommon. The fourth one is the multi modular container for gravel. Those are just about everywhere. They also commonly have to changer, so they can run 3 shipments with one truck. Its really nice becasue then you can order 3 different fraction and just pay for one transport. Fifth one is a tall 4 stackers. Those are a bit more uncommon. Really just exist in the north, Down here south they usually run mostly 3 stackers. The thing with the 4 stacker is that they can´t run them with a crane on the truck. So they can´t load them self, they have to swich trailers. So they have to drive to a parking lot to swich trailers, that is only a point if they have very far to drive, that is never the case down south. but up north that is pretty common. Our north is very similar to your outback, but we got cold and raindears in steed of warm and kangaroos. The sith one is also really common. But they usually drive around with a trailer behind it to load. When the logs are carried to the saw mill they ground down all the roots and branches to make heat, electricity and fuel of.

  4. I havnt seen a fully manual in decades... a while those manual-automatic hybrids was a thing where the truck had like 4 manual gears then there was a automatic shift up half gear. Go back a bit more (like early 80tys) those half gears was half automatic. That is, you dont neet to clutch but you still had to hit it. There was also some version with 4 split gears. (I never seen those, only heard about them)

  6.  @Aquarium-Downunder  There was a other video as well. I think those videos was really good. Showing stuff that is fairly common to us, but uncommon in the rest of the world. https://www.youtube.com/watch?v=aUuYiTApccI A other supersize load. Those are very common on some routes, typically between a place that makes stuff and the harbor. And it can be like 100 or 200 km. And typically the last 5-10km is right throw a city. (well, the outskirts) Second one is just a normal road gravler. I guess they wanted Norway here to. Norway have smaller trucks than Sweden and finland. The text is all wrong here. This is road maintenance, not anti slip graveling. The third one is a huge 4 stacker with a crane, those are only legal in Finland, not in Sweden. That truck is probobly 34 or 35 meters long, but only got one trailer. Those trucks as far as i know, only common in Sweden and Finland. And this one is 2 or 3 meters longer than is alowed in Sweden. The fourth one is a ultra large timer truck. This is sort of a cheat. They run it on sort of a farm equipment license. So its excluded from all maximum load limits. They also have a special concrete road bed for it, so its also excluded from the normal maximum axle load. Looks like they are runing almost 20 ton per axel. That is pretty much train loads. The fifth one is a normal snowplow with gravel and/or salt dispenser. There is probobly over a thousand of those. Really common. The last one a dual modular asfallt transporter. Those are a bit trickier than the gravel transporter. The video kind of missed the point of them. It need a second wagon to fully work. Those are also super common. Wouldn´t suprice me if you had those in Australia to. Would work just as well there.

  7.  @Aquarium-Downunder  We abolished the police.... escort about 15 years back. There was more and more escort missions, so they privatized it. I don´t know the exact stats, but the truck have to be pretty big before its needs it. The stuff i work with is almost 170 ton and we don´t need any escort for them (i´m not a driver, just doing the calculation and costing). Siemens that trasported turbines just next to where i use to live transported 250 ton containers that was 4 meters wide, 7 meters high and the whole rigid wagon was about 30 meters long (+truck). They needed two escort cars.. I don´t know how may wheels it was, probobly in the 80 range. The biggest i seen uses 3. But most commonly there is no needed what so ever. Just put a sign on the back go. Or if its over 3.2 meter wide you have to get a special one time permit. But its like online shopping if its not to big. Just sign in, pay and you have your permit. Typical sweden. The government agency are to anti social to answer a phone call

  8. This also reminds me of volvo 1994 hybrid truck, the ECT, that was way ahead of its time. But there was a few flaws with it so ot was totaly redesinged. Then they lossed intest and well.. the concept was dead for 10 years before they started it up again
