Trucking in North America vs around the world

As far as I remember, there is a maximum slack allowed between pin and bushing in the tongue. During safety inspections, pins and bushings are measured and have to be replaced when worn out. In my opinion, that system is not necessary if everything is tight.
The pintle hitch system on the American continent is a loose fitting to begin with and it needs the ram. The type 30 brake pod does not necessarily put much pressure on the tongue compared to the potential weight in the trailer.

 

american tuftrac suspension on brazilian MB actros 240lbs lighter than air suspension

 

I would still want the airride.

 

Depends on the application.

 

And culture.
From your past life/experiences/history you will prefer the 6x4 whereas as i will go for the 6x2 (which is automaticly airride with the tag being a liftaxle)

 

In brazil they have toll by number of axles on road, it is important to have lower numer of axles on ground while empty of course. That is why mb now offer lift drive axle on 6x4 like volvo and sisu but only on air suspension.

Scania still offer spring suspension 6x2, not sure for volvo, mb drop it with mp3.

 

That's fine for your application, not so much for others.

 

Opinions on this are............?
