Long truck difficult turning - converter dolly active steering
An converter dolly with active steering axles used in an A-double combination vehicle with total length of more than 32 meter and weight of about 80 ton. This long combination vehicle (LCV) is capable of making very tight turn at round about easily with the help of active steering system in the custom made converter dolly.

We need this in ets 2
Порнуха это, лучше первый подруливал бы

Why not just implement this on the trailer itself like we have in Australia and New Zealand. Usually the last 2 axles on our quads are steerers with a similar concept and reduces turning circle with added benefit of reduced tyre wear
That's what European trailers do as well. It is not very effective on tight European roads when you have to take a sharp turn with a tandem.
Happie 🐔
This is a hct trailer?
In France you carry all the round about with the back semi😂😂😂
Trucker here: pay me 5000€ a month and I’ll drive that . If you’re gonna pay me just 200€ over my normal salary like most companies do to get into that death machine, you’re mistaken. No trucker should accept driving that. It’s less jobs, two trailers one driver. We are already exploited enough the proliferation of mega trucks is unsafe for us and traffic
All well and good on a nice big round about with nothing else on it now try with car bikes and other trucks on it at the same time lol how does the rear steer ? If by remote that would be illegal as both hands must be on the wheel.
Это сумашествие. Это не Австралия с её прямыми и безлюдными дорогами. За таким составом нельзя чисто физически уследить.
Self-track the back of each trailer to reduce cut-in and tyre drag still further.....this is old technology, now very underated
The dollys effect on the exit looked lethal for other road users, headboard of the second trailer way over to the right and then swinging right across to the left into opposing traffic.
Exceptionally when its icy

What about intersections?
Cool
To start with, the rear overhang on the trailers goes a long way to steering the dolly to track wider. Second, the dolly steering system could get you into trouble with the long front overhang that is favoured in Europe. A further observation is made from about 13 years ago. An Australia operator had a trailer that had a steering tri axle group, which steered outside of the width of the trailer. This had to be used carefully, as if not careful, you could wipe out a car that is parked on the side of the road.

Лучше бы на первом прицепе два моста и на втором два моста поворачивались
Gues u can scrap your plans of this invention if plans of that wacko Timmermans will take hold. He plans to move the bulk of goods in the future by ship and trains...
Looking at the wheels of the steering dolly and third axle on second trailer,it is clear there is scope for wheel loss and accelerated wear from side forces greater than rotational direction.
These HCT combinations already drive around in Finland without any dolly steering, works fine.
I drive in Germany now , they have some logistics centers and factories in small towns and villages , with corresponding small infrastructure... My salary will go to pay for damages which this thing will do in so many small places which our bosses send us to visit...
Good thing this is designed for Sweden then and not Germany....
El mejor mega es el que la wmpresa te respeta como conductor y te sueltan el dinero que bles tu conducion y trabajajo sino que trabaje quien quiera aceptar yo nooooo con dinero baila el mono
So how does the dolly steer? Human, or computer?
Wao, Nice turning at Round About
We do that here in Australia without steerable dollies.
Yeah but your roads also have space for that.
In aus they also have the ringfeeder at the very back of the trailer so when the trailer turns it will swing the dolly wider making it work even better, unlike the scandanavian setups where the hitch is half way between the rear axle and the back of the trailer meaning it doesnt get the same outward pulling effect
@@Noi5ee most of our roads are narrow and rough.
@@tristangornall8649 the ring feeder halfway between rear axle and rear of the trailer won't change how it works. The dolly itself doesn't do much work and it's actually the turntable on the dolly and the hitch that do the work.
@@aussiefirie Not compared to Europe. You will never know the true meaning of "tight" until you have driven in Europe. There is a reason why AU can accommodate large US style trucks with many linked trailers while that is not possible in Europe.
Still unsuitable for UK roads.
OMG PLS FiRE THE DRONE PILOT :-D
3:57 your dolly just killed family in the caravan
Я с тобой согласен это авария
@@Арғынортажүз a par klobas pa to?
LOVE Skars Nice
Try that on snow.
An American truck whit just one trailer wouldn't have made it through there lol.
American truck can do it easily with even 53 foot trailer, it depends of the truck sleeper type.
Great videomaking! lol. Maybe you should let professionals make your next video..
Ghshw
eu tinha pensado em uma suspensão frente de fusca na carretinha de moto para dirigir para tras com servo mas isso ai já o topo da emoção
rear steering on the tri-axle trailers would also improve the turning circle of this combination.. or didn't the designers think of that...
I would like to think that the designers thought of using the system with existing trailers without the steering axles for maximum interoperability...
the system is designed to be used with conventional trailers to make it as versatile as possible, you can use it on any trailers then rather than having to go to the expense of having specialised trailers as well
I like to test drive two trailer set up with the fifth wheel on the lead trailer .It make it easy for reversing .Can the drive control the steering in the dolly of this combination .It make it more easy to reverse .
I agree with you Teri. Self-tracking or rear steer axles have been around since at least the 60's, from companies such as Primrose-Ceshi, Merriworth and BPW. They reduce tyre ware by reducing scrub, cause less damage to tarmac and reduce cut in, either forward or in reverse. I think they should become mandatory, especially if UK trailers increase in length, which will happen
Simon Taylor .Will there be 53 on the road instead of the 45 .There seem no major difference until a tiny round about or yard.
Irgendwie für europäische Strassen sinnlos, denn sowas dürfte nie zugelassen werden. Das überholen ist höchst riskant - OHNE Begleitfahrzeug dürfte sowas sowieso nie auf die Strasse + somit hat sich der Vorteil schon wieder erledigt, denn man benötigt wieder eine zweite Person. Einzig eine Zugmaschine ist einzusparen.... Ob sich das rentiert....
Die sind 6,5 m länger, als das, was bisher zugelassen ist. Wer da nicht sicher überholen kann, der kann es auch bei den jetzigen LKW nicht und sollte es dann halt sein lassen.
Stimmt nicht - sieht man ja im Video, dass dieses Gefährt um eine komplette Sattellänge länger ist. Auch die bereits im Einsatz stehenden Gigaliner dürfen nur auf bestimmten Routen unterwegs sein, weil das überholen zu gefährlich ist!
Schau dir doch die Vorschriften an, dann siehst du, dass es genau 6,5 Meter mehr sind.
Du redest hier von Gigalinern und nicht von dem Gefährt hier im Video! Aber auch der Gigaliner ist unsinnig und viel zu gefährlich: www.vcd.org/themen/gueterverkehr/gigaliner/
Der Autor deines Links hat offensichtlich keine Ahnung von Physik und Technik: Höhere Gewichte bedeuten nicht höhere Bremswege. Das sieht man schon daran, dass die Bremswege von LKW nicht höher sind, als die von PKW. Auch die Bremswege von Gigalinern sind nicht höher, als die eines ganz normalen PKW.
JAMAIS en France j espere bien ...
Hello Dr. Islam, great conceptualization and a very promising engineering execution. I wish you and your team would create a great steering-maneuvering system in the post euro modular era of European Transportation.
Wow fantastich good job
If I was head of transport for a company, would I really benefit from having this dolly for 1 truck driver or would i benefit from having two drivers for the same two loaded trailers?
One driver cost less than two drivers
Ofc, HCT combinations aren't suitable for all kinds of driving, best used on long hauls with big roads
Weird.... german railway companys "DB" department for logistics is developing mega trucks...
It's Volvo and Scania who develop this tech, DB Schencker is just a customer and partner in the project.
@@davidwittberg683 yes sure - I wasnt speaking of the technology of those longe trucks... I'm shocked that the main RAILWAY company of germany intensivies its ressources in introducing bigger TRUCKS ;-)
tnie opony w ostatniej naczepie jak nic, gdyby byla na maxa zaladowana to ja niewiem czy na asfalcie opon by nie zerwalo, na pusto to mozna cuda-wianki
Smaller lighter automobiles sharing the roads with larger, much heavier trucks. As a trucker now retired I would not be completely comfortable with the odds. Little matters as long as the profit margin increases relatively steadily I suppose.
Absolutely fascinating!!
