Why do so many Americans hate European trucks?

A dump truck is a straight truck. Make it a 5 axle tractor trailer and its exempt.

 

Yes but it also needs to be way too long just to fit into bridge laws. Here tipper semitrailers for construction are no longer than 24ft, very stable you can unload just about everywhere.

You can get 5axle truck with 88185lbs with already with 215inch, law does not limit you to wb , it could be even shorter but than you will have to replace some components behind cab to create space for axle

 

Yes, like your statement that the bridge law has nothing to do with bridges.

 

Does any one has any idea how much load that extra axle on a super dump truck actually takes, or is is just a way to dodge out from the rules of the bridge formula?

 

Well, obviously it has to do with how axles are spaced and loaded in regard to our highway system, including bridges, or there would be no need for the law, would there. It is NOT specifically and solely for bridges.
And when did I say that it nothing to do with bridges? I said it was in regard to and called "bridge law" because of the bridge between axles, not bridges.
I am still not sure that you can grasp the distinction, and I am ambivalent as to wether or not you do.
In regard to the theme of the thread it is diminimus. We do not like European trucks because they do not work well here (and they are UGLY).

 

I don't think so. Not in all the countries mentioned, for example Belgium.

For those who can read dutch:

1.4.1. Elk voertuig of combinatie van voertuigen moet aan de volgende voorschriften voldoen indien zij erop toepasselijk zijn:

1.4.1.1. De maximale toegelaten massa mag niet hoger zijn dan de massa vastgelegd door de hiernavermelde formules, in dewelke A de afstand is, uitgedrukt in meters, tussen de eerste as en het middenpunt van de achteras of groep achterassen.
M < 12.000 + 4.330 A
voor A < 3 m of M < 25.000 kg.
M < 17.000 + 2.700 A
voor A > 3 m of M > 25.000 kg.

Bij motorvoertuigen voor internationaal vervoer met vier assen waarvan twee gestuurde voorassen mag de maximale toegelaten massa in ton niet hoger zijn dan vijf maal het maatgetal van de afstand in meter tussen de voorste en de achterste as van het voertuig.

If I understand correctly (I think Daf105paccar can confirm if I'm correct or wrong), maximum GCW is 17000 kg + 2700 x distance (in metres) from 1st axle (front axle) to center of trailer axle group.
So to get to the maximum 44000 kg, you need at least 10 metres measured from 1st axle to center of trailer tandem/tridem. Anything less and GCW will be reduced.

 

not european solution, it is dutch solution, this is not used legally anywhere else, you will find some of those trucks here too, but they are too heavy, too much driveline, complex steering and hydraulic suspension are not needed.

europe dont have solution in range of 40t rigid.
you guys can use 5axle at 50t, ireland can have 39t, switzerland 40t, we have 40t , austria and germany dont allow 5axle trucks, they are common in finland 42, dont know other countries. but they are not frequently used and i am not sure where they are legal.

here since 1.1.2016 5axle trucks are recognized by law as 40t , before they were 32t same as 4axle.
so far market is quite limited for this, i know for big 2crane trucks, few mixers, few roll off tippers.... and larger number of tipper trucks.


in czech and slovakia they often use 4axle rigid chassis close coupled with 1axle semitrailer that is fixed on truck, trailer axle steers instead...




till 1984 they were using same thing in germany coupled on 3axle trucks, than 2axle trucks were 16t, 3axle 22t, 4axle were not legal, truck combination was 38t max.

they hook 1axle trailer to 3axle truck to get 32t
my father had magirus mixer.

there was even combination of 2axle truck 16t + trailer with 2axles, front axle on trailer was driven, and rear one was widespread, so this was 36t....germany than introduced law that says 2.5m distance between last trucks and first trailers axle,

in austria you can buy semitrailer that can move king pin when driving on road and unloading as rigid......

we have same law as in switzerland

all together 40t,
single axle 10t
double axle >1.3m x <1.8m = = 2x9t,
double axle x > 1.8m, is seen as two single axles (2x10t) or separated axle groups
triple axle 2.6m<x<2.8m = 24t
triple axle x>2.8m= 27t

but axles must have at least 1.8m between them to be seen as individual axle groups.
you can have all axles seen as single axle group than you have weight distribution problem as you get max 5x8t, this require longer wheelbase

many brands have wide spread between first two axles, this makes problem with wheelbase as you need at least 1.8m between 2nd and 3rd axle. if we still use wheelbase between first two axles as used before we could get wheelbase of only 188inch with pusher axle.

 

as much i could figure out it is 12000lbs

 

Correct.
You need 10 metre(or 394inches or 33 feet) from the center off the steeraxle to the center off the traileraxle group.
This is for a tractor trailer,not a straight truck.

 

but NL law is stupid in its way, it allow 10t on non driven axles and 11.5t on driven axles,

so 8x4 truck can have max 43t, while 8x8 46t, i dont see reason why should truck with same number of axles carry 3t extra because of 2 more driven axles
