Is it possible to (actually) overload a semi?

Most of the time, from what I've seen, the trailers will give out before the trucks do.

 

things off road are a lot different than on road

here on road single drive truck can weight up 275000lbs(depending of truck) in some cases even more

but off road there are different breakdowns on drivetrain or suspension caused by heavy weights

but on construction site when you are starting with 160000lbs on 20% uphill

when you are picking construction machines with lowloader trailer and truck started to jumping on start , when twin clutch start to burn, and wheels start to spinning on non paved surface in those situation it is easy to break even big hub-reduction axle ( 6x4 with rear end rated for 80000lbs)

 

Overload? Try to,everyday...

 

More like Bud Heavy.

 

I haul 140,000 loaded and 75,000 empty. Pulled in the scale yesterday (closed) to clear the snow off the taillights and and watched a 5 axle log truck trying to get his weight down to legal. He dumped about a dozen logs off and when he went across the scale he was at 156,000. Still had a ways to go.

Truck will pull it no problem, the more weight the more rubber needs to be on the road

 

I know of a truck that is used to test transmissions in Michigan that runs up to 264,000 pounds. That is with two trailers behind it on private grounds. It is a Pete 389 with three drive axles. Hasn't broke yet.

 

Ouh yeah, easily!!!

Especially it is easy to overload dump truck ore logger truck.

I see brokex axes, blown tires, bent frames every week

Wrong weight distribution is a problem too.






Funny overload car near my home...

 

Yet another stellar example...
