Did you know that the Scania V8 770 is no longer the most powerful engine? Click here and see the new King : ruclips.net/video/0t-OeadhGYM/видео.html
This is been King over a 5 years.
Sisu Hybrid 1140hp and 5000Nm
m.ruclips.net/video/8pYKKZNJIfA/видео.html
Still it is. Scania is still king because of powerful V8. The Shacman's Weichai 800hp is still cannot be beaten by Volvo's 750hp in terms of inline six cylinder category.

Why do people like scania
The 10x8 is also fairly common here in europe for tipper trucks that need to go offroad and can be ordered from a large amount of manufacturers as well
I'd say that 8x4, 8x6 and 8x8 are far mor common than 10x8...
@@fab8657 you are right. thats why JLee used the term "fairly common" not meaning it is the most common.
I know 10x8 just from heavy hauling special transports o.o
@@BruceCarbonLakeriver in northern Europe there are some big tipper trucks from Volvo ( FMX ) with this config
@@SLiNCOrE Yep :)
A 4x2 tractor with a 3-axle trailer is some kind of European misunderstanding, it can only drive on highways and in summer. A little snow and they become dangerous and cause chaos on the roads. In northern Scandinavia we call them mosquitoes, they disappear with the first snowflakes and appear when the snow melts
It isn't a "misunderstanding"; it is a configuration for specific purposes.
It's commonly because of Scandinavia have money to buy expensive trucks. In East Europe - Ukraine, Belarus, Russia - 4x2 is commonly used trucks. And they drive on highways in winter without any problems. Yes, after heavy snowfall they get stuck, but, to be honest, no other trucks can drive through it
@@brianb-p6586 The same work can be done with a 6x2 tractor and a 2-axle trailer, it is a safer configuration and there would be no problem in winter
@@derbinskij93 4x2 gets stuck where 6x2 drives without problem, there is a big difference between them due to weight distribution
@@aanriuha yeah, you missed one thing, if you want to distribute load evenly you need to have a tadenm axle unit at the very back of the trailer, a tridem unit sits further forward improving manouverability
Europeans have the possibility of disconnecting the rear axle from the suspension on 6x4 models, allowing it to be raised. A very important fact that is not discussed in the video.
@@vid4944 wrong. I drive a scania 6×4 that can lift the rearmost axle and via clutch diconnects the drivetrain
It's a special option that I think only Scania has, it's not very common
@Vid no, you misunderstood.
You're thinking a 6x2 taglift, we're talking about a 6x4 taglift. On that system, Scania can disable/disconnect the driveshaft to the rear axle and then lift it like a boogie. Effectively turning a 6x4 into a 6x2taglift with a push of a button
@@vid4944 no dafs with that exist(normally) only volvo and scania offer it
@@stevengunter4990and it is great on Volvo, when you are empty you can just lift the other axle to air and you get more grip and smaller turning radius.
You should do a video on trailer configurations, like standard, A-trains, B-trains, heavy duty, flat beds, and self steering trailers if you haven't already.
Thanks 👍 i might do that
@@TruckTropiait would be chaos, because europe has its own rules for trailers and then there are rules for us in Finland for our own trailers.
Don't do it.
We know the concept from this comment.
@@TruckTropia Don't do that.
Thank you. A very good presentation. These various drive axles all have something in common - the final drive (differential) ratio. This ratio affects pulling power , fuel consumption , top speed and engine rpm. This ratio is usually stamped on the differential case. A good rule of thumb is : the higher the ratio, better pulling up hills although with higher gas consumption. Good for gravel pits and very heavy loads .A lower ratio is poor for climbing but allows a higher road speed and better fuel economy. Good for long haul ,flat terrain deliveries .
Basically having more drive axles gives better traction and haulage, doesn't necessarily make the tractor more powerful. The real engineering trick is this differential ratio.
In presence of gearbox why differential ratio?
@@khursheed.fateh.786 I can imagine the same gearbox can be adapted to different targets by matching a suitable diff, which is a relatively cheap part to differentiate upon. If you were to use different gearbox ratios it would become a much more expensive game.
you forgot 10x8. the 10x8 is widely used in the Netherlands. And the 6x6 and 8x8 are quite comfortable (that's my opinion)
They are not very common anywhere Else 😅 ok thanks for sharing 👍
@balkanduck there are hunderds of them
I heard they're not going to be as common in the future though, companies aren't willing to pay the extra for the 10x8 anymore. I always loved it when they showed up cause didn't have to pull them out near as often as the 10x4
@balkanduck here in the Netherlands we got a company who is specialized in putting an extra axle under trucks to comply with the 50ton gross. We got a lot of them here all brands
@@TruckTropia correct, very specific trucks built for Dutch regulations.
Even 10x10 exists
8x4 configurations are also usually found on heavy haulage trucks here in the UK and Europe. It offers great weight distribution for transportation of abnormal loads (industrial generators, silos, large concrete pipes, heavy construction machinery, etc...). Sometimes, they can be 8x8s if a higher traction and pulling power is required for the weight of the load, but still follow the conventions of 8x4s for steerable axles (/4, standard 8x8 and *4 as appropriate for where the steering axles are located).
The axle configuration of European heavy haulage trucks is usually seperated into a single forward axle and a set of 3 axles at the rear, with the forward axle of that triplet being steerable (8x4/4). It is most common on articulated tractor units. However, 2 sets of 2 axles (2 forward steering and 2 rear driven) (standard 8x4) can also be configured for a heavy haulage artic. The single forward and rear triplet axle set (with a steerable tag axle) (8x4*4) can also be configured, but is most commonly found on rigid/box (what Europe calls Tandem) trucks.
True I've got a rigid box with tandem trailer on my driving school this year. It was a MAN 26.480 with XXL cabin and a 2 axle tandem trailer. For doing all the classes not only truck but also the big trailer class, for my license (I passed btw :D).
While you are right how the normal heavy haul config looks, it is infact not 3 rear and 1 front axle, it is classified as 2 front 2 rear, as the 2 front axles are directly linked to each other, the distance between the front 2 amd rear 2 is just 0
Fantastic video!
You should make a video on trailer configurations. We have some 3 axle trailers where the front axle lifts and the rear axle steers, meaning you get zero tyre scrubbing in turns. They are a joy to drive.
8x8s are very common on some logging trucks that go into the bush, I’ve heard the are extremely well designed and that the plantation has brought more of them
we Indians use 4x4, 6x4, 8x4 and 10x4 trucks. the Tata SE 1613 Turbo comes with 4x4, which makes it a capable truck for off roading, and the Tata LPK 2518 Tipper comes with 6x4, which is helpful for construction segment. we also have Volvo FM 420 Tractor with 4x2 Axle Configuration, which is used only by Delhivery, which is an Indian E-Commerce Company. The Volvo FMX 420 is used for mining, which comes with 8x4 Axle Configuration.
The 6x4 long nose semi might be the norm for over the road trucking in the USA, but the short 4x2 conventional semi is also fairly common as well. Especially in the less than truckload realm where city pick ups at multiple stops or ease of use with multiple shorter trailers between cities is an advantage.
And in certain parts of the US, the 8x4/4 semi is also decently common, especially the PNW, mountain west, and in Hawai'i. Though those in Hawai'i tend to be on much shorter wheelbases than their PNW/Rockies cousins.
The people who run this channel seem to believe that all trucks in the U.S. are identical.
FedEx and UPS have a lot of 4×2 pulling two or sometimes three pup trailers.
While 4X2 is uncommon in long-nose highway tractors, which have sleepers and run long-haul routes, there are also shorter-nosed medium (Class 6) and heavy (Class 7 & 8) tractors (normally with day cabs) such as the Freightliner M2, Peterbilt 537/548, and International MV. In addition to the FedEx trains already mentioned, I've seen them pulling beverage trailers and flatdecks with building materials.
I live in a big city in the US and I still RARELY see a 4x2. Literally the only 4x2 trucks I see are FedEx trucks, but that's it
@@brianb-p6586 Much like Euro trucks aren't all the same. Geography and population density play nearly as big a factor as actual legislation regulating trucks.
In fact, being from Hawai'i, semis usually only pull containers from port, heavy haul, and ag use. Most everything else is done with straight trucks of varying sizes and is more similar to some asian countries because of it.
The most common combination in New Zealand is the 8x4 twin steer either as a rigid truck and trailer unit or tractor unit pulling a quad semi or B-train. And it's mostly down to the rules around load distribution and RUCs(road user charges).
Looks like good condition trucks
Purposes list
4x2: Trucks commonly around in Europe.
4x4: For offroading purposes.
6x2: For maneuverable trucks with trailers.
6x4: For American trucks purposes.
6x6: For military purposes, dump trucks and firetrucks.
8x2: Trucks constructed with a crane.
8x4: For offroading dump trucks.
8x6: For offroading firetrucks.
8x8: For offroading military trucks.
10x4/6: For heavy duty purposes and construction trucks.
Or you know logging...
Can also get a Tridrive too 6x8
6:54 This configuration is much more complex, because it is used for construction, heavy duty tasks, and vehicle carriage tasks. Nice comment. If you'd drive the truck, with the 10x4 configuration, brakes are better!
Configuration, not "config".
This video confuses me a little...
All axles rotate otherwise they'd be skids :), but it's being used in the steering sense here. In the UK it appears we just call them steering axles - '2nd steer', 'rear-steer' etc.
I've always thought of the 1st number being the number of hubs on the truck, with a wheel being a rim and tyre. Hearing someone say a 6x2 has 6 wheels feels odd as to me there are two wheels on each rear hub.
Working at DAF dealers for nearly 20yrs now, I still enjoy picking up knowledge - it never stops. Thanks for the videos.
Pretty cool video, thanks!
Hey I like the 6x4
We only refer to the 8x4s as twin steers and we use them as they turn great and preform very well. We use them on hour road trains too.
Truck Topia hearted our comments.
Here in India 10x2/4 and 10x2/6 trucks are becoming popular.
i really like the trucks where least one rear axle rotates opposite to front one(s)
everytime i heard 8×4, i always remember new zealand trucks, and that is beautiful😎😎
This is a super common Truck.
Thank you so much for this amazingly well-explained vidéo! It was exactly the kind of information I was looking for. Great job!
Thanks 👍
Amazing Video So Informative......❤❤❤🇮🇳🇮🇳🇮🇳
Thank you.
Thanks bro ..
Salam from malaysia🇲🇾
I see that 10X4 truck from the Netherlands almost every day. It's super handy for Convoy Exceptional.
Nice, Netherlands have some great trucking rules.. 10X4 are very very rare in most countries.
Traction varies depending on powered wheels. Stability varies depending on amount of wheels. Maneuverability varies depending on maneuverable wheels.
I love a truck with dual exhausts.
Trucks have common "configurations" as well as purposes.
Thank you so much, I always liked to know about different configurations, you nailed it in one short, neat and very informative video.
Happy to hear thanks 👍
Remember that strong springs are better, so offroad drives are smooth.
this was strangely very interesting and informative lol
Remember that, at higher configurations, with also bigger wheels, you don't need chained tires, because it has higher power and traction!
Let's get commenting!
Thanks for sharing very informative video.
Your welcome 👍
5:41 and 6:42 are the most popular truck axle configurations in india, which is used for transporting cement silo, cement bags, fuel tankers and also for container applications
It's mostly 8x2 and 10x2 in india
@@dmitrich9542ashok leyland 3718 is the great example
I Like the 8 x 8
4x2 best common in Europe and 6x2/4 in Europe 😊😎😎
As a truck driver, I have learn a lot today. Thank you @trucktropia
Happy to hear 👍🚚
In south korea, 10x4 is one of the mainstream type axle configuration. This type chassis combine to opendeck cargo or box
4x2 is great for acceleration, greater turning radius, and also fuel saving but also can put u in a high risk for getting tripped and as for european cab 4x2 is more bouncy
6x2 and 6x4 is be far for me the best configuration not only u can carry more weight and more power with 6x4 but also more stable to drive. So if u want to own a truck i suggest to get 6x2 variant or 6x4
Do not follow his advice without thinking about it carefully, a 6x4 and 6x2, cost more and weigh more, as long as that id not needed it will cost you money wich nobody will compensate.
@@stevengunter4990 of course it comes with more money to spend but it was the truth that 6x2 variants and 6x4 are better than 4x2 and adding more weight for me is better too
Welp im not forcing you to get 6x2 or 6x4 and im not saying having 4x2 is a no no
Everyone has their own preferences and tastes but for me 6x2 and 6x4 is better cuz for me they are more comfortable to drive
@@aokusazimniy8but thats very one sided, most people shouldnt buy one just for comfort and rather spend the money on full air suspension(maybe even independent front suspension like volvo) and for most people adding more weight and tire cost and fuel usage is detrimental in todays european market
@@stevengunter4990 What do u mean by one sided while i said that "everyone has their own preferences and tastes"???
And so what about that? 6x2 and 6x4 proven to be perform better than 4x2 at handling heavy cargoes and stability
And why u keep sticking on cost while it is obvious that having another axle is cost more
I have a 4x2 and a 3 axle trailer and can still be 50t total (the max wheight in NL) i only drive on the asphalt and sometimes mud, but never get stuck. Yes a 6x2 is more comfortabel but wheightwise you dont need them
Nice video!
This video is also about "common"
6x2/2 configurations are all about the hyphen. Or a slash can maneuver the tag or forward axle. The hyphenated 2 or slash means a tag or forward axle.
6x4 yang aku suka
Hello! What a nice video! Thank you! I would like to ask, if anybody knows, what are the differences between Pusher (6x2/2) and Boogie (6X2*2)? Which setup is better?
2:38
@@sanjai784 What 2:38? What is the difference when tag axis is in the middle, or when its in the back of the truck? Longer wheel base, shorter turns, something with the weight maybe?
@@EstonianRescueServices Here in the UK, most trucks have the pusher/midlift axle, which is fine for road use. The bogie/taglift is used for off roading because you get more traction and less likely to get stuck.
@@thebrow117 i have a question about that (not really this topic).
Why have UK trucks 3 axles? The max wheight is 44T right? I have a 2 axle truck and a 3 axle trailer and can have 50T total (im from the netherlands) so i dont get the point of the 6th axle? Front to back i have: 1x9T 1x11.5T 3x10T. How is that in the UK?
There are 6x4 chassis where theres
2 axles together at front one being steer one is fixed
With a steer at rear.
Mostly seen used for double decker buses but its still a base truck chassis
Please add the metric equivalent of the imperial units, too. People around the world accepted English as first choice for an international communication, thus respecting your language. Now is your turn, also from respect display the international metric equivalent of the imperial units. Global Thank You for That.
The image at 4:11 is not correct, you are missing the white circle on the front axle. The picture really shows a 6x4 and not a 6x6.
GREAT WORK KEEP IT UP!
Thanks 👍
Finally lol!!! I love my 8×4 DAF and trailer
👍
Informative, thank you truck topia
Very well explained buddy ❤❤
Thank you 👍
Nice explanation and video,im playing euro truck simulator 2,so now when i need to buy a new truck im choosing 8x4,the most expensive one lol,yeah i will manuever harder which is bad but i will carry heavier trailers more easily
6x2*4(tag axle) DAF XF, XG, XG+, CF model FTN; 8x2*6(tag axle), DAF CF model FAX.
There are a few 10 x 10 configurations here in America, I don’t know about the UK, primarily on military, rotary wreckers, or the new military PLS
You must only watch this video at 1080p.
nice video 👌👍
My lifetime dream to achieve driving 5 axle 10x10 for special heavy haul off road trucking... build my own truck for heavy haul, with hydraulic suspension, absolute control of differential locks. Also apply my new innovations devices to increase quality, effectiveness and efficiency of the trucking...
Nice video. I have a question: What is the criteria for using double wheels? From what I have seen, only the non-steered drive wheels are double, is this correct? There are exceptions? (Talking about regular trucks or semi-trucks)
Two driving axles don't allow trucks to carry more weight in Europe. It's only the amount of axles, the distance between the axles and if the axles have single or dual wheels that determine the maximum total weight.
It's also very common to use Robson drives. This is a free rolling cylinder that is pushed in between driving and free rolling wheels so both wheels will be driving wheels. The Robson is only for temporary use because it causes wear to the tires.
Nice 😘
Front wheels: Maneuverable wheels.
Rear wheels: Main wheels, and maneuverers.
In India, we are using trucks with upto 6 axles in a single chassis.
Me before the video - numbers Mason what do they mean?
Me after the video-numbers Mason I know what they mean.
Well, on April Fools' Day, you might've expected a joke video, but instead, we got a serious, and in fact, very informative one. I really wondered what those slashes, hyphens, and asterisks meant. Thanks a ton (give or take, 40!)
I heard some 6x4 chassis equiped with taglift axle too.. so the truck can configured as 6x2*2 for fuel saving..
Is it true?
True Volvo have that 👍 tandem lift
@@TruckTropia scania aswell
Remember that 6x6 trucks are common in dump trucks.
Realistic!
6x2 is widely used as a solo truck but i would argue that 4x2 are used way more often as a tractor compared to 6x2s
In Europe, yes, 4x2 is probably more common, but in the UK with higher weight limits, a 6x2 or 6x4 is more common
The 6x2/2 is also a very common truck in germany and the netherlands for hooklift container transport
So we heavy haul In west coast American we all have regular 8x4/4 just regular semis with drop axle in front that turns with steers.. and 4 axles in the back too.. 24 or 28 tires depending if rear drops have 2 or 4 tires on the 2 drop axles on the trailer.. 101k-105,500 combined gvw depending on state u go to..
Which would be better truck platform for an overlanding truck a 4x4 or a 6x4 ?
As some countries manufacturers like mine(INDIA) rarely offer 4x4 for civilians and only option is to cannibalize auctioned ex military vehicles which would have huge wear and tear but the 6x4 is available for civilians.
8x2, 8x4, and 10x4 configurations are also for construction purposes.
If I have everything prepared, I can do this video. What things I should prepare to make this video?
Thank you. I'll have to keep this for future reference 😂I think my brain is a little old to take in , in one sitting 👍👍
😂😂😂
When I was young i though the more wheels the truck had the more truck lools cool
and didnt know how each wheels are helpful and how expensive
The configurations that are so common are: 4x2, 4x4, 6x2, 6x4, 6x6, and the rest.
The configurations that are common constructions at Europe is the 10X4.
1:14 What do you mean about a fixed trailer behind?
4:41 That's why they're not so common.
Are there european trucks 6 axle with no liftable axles and extra rotatable axles and not go offroad?
I don't think so. Max 5 axles - as standard anyway.
1:40 Traction is much more better, then you've driving a Firetruck, than you'd expect poor traction.
What's the purpose of maneuverable wheels even when powered?
4x2 favori
In India we have a rigid truck model which has 12X2/6 configuration
What if it has tracks, or is a halftrack or has individually powered wheels?
Not all 6×2 are single tires they can look like the 6×4 but without the one of the rear axles in the rear being powered and 10×4/4 or 12×4/6 or in extreme cases 14×4/8 is common for heavy duty vocational work in America and Canada and can be ordered by a few north American truck companies. Plus with what Chase Barber said (owner of Edison Motors) with the ability of e axles he could power the trailer as well so in Michigan case he could do like 22×22
Thanks for sharing 👍
There is nothing unique or special about Edison Motors. eAxles are readily available from multiple axle manufacturers (of which Edison is not one) to any truck manufacturer (and Edison is not really a truck manufacturer). Powered trailer axles would not be useful in most trucking applications.
Comment on hold.
It's true that a non-driven rear axle often has single tires (when the driven axles has duals), or has narrower tires than the driven axle (when the driven axles has wide-base singles) - this is common on 6X4 trucks (especially in Europe) and on highway coaches (buses). It is also true that this is not always the case - a 6X4 can have the same dual tires on the non-driven rear axle as on the drive axle (especially on 6X4 heavy highway tractors in North America).
Sir, why truck manufacturers like Volvo, Iveco, DAF, Mercedes etc. use small size wheel tag axle or lift axle in their semi truck unit in United Kingdom, please explain.
Is there a 4x2 truck that the back axle rotatable?
in switzerland you see a lot of 10X4 with 3 axles in the front and the 3 of them are steerable and the 3rd on is also liftable. you see them a lot as dump trucks or for asphalt tranport. and the multi axles steering was invented by SAURER a swiss truck brand that desapeared in the 80's with trucks like the Saurer d330 BF 8X4. 330 stands for 330 hp B for low rpm torque and F for cabover
Multi axle steering was not invented by saurer, not in a lifetime, some trucks had 2 or more steering axles way before that, just look at old fodens.
In my city u can see all type of this almost
What are the built inpurposes European trucks?
You put some of the video with truckers of Europe 3
How about a Chinese Six. That was a strange configuration.
Imagine a 10x10
They exist. Tatra, ginaf, terberg, volvo and scania all have them
Tatra also make 12x12 and 16x16
