Tri axle Freightliner cascadia

You’re comparing heavy haul to a PNW maxi setup. Apples and oranges.

 

B train ftw.

 

We’ll ya got me there.
I don’t even know what a PNW load is?

 

Either an A train, B train, or 4 axle truck with a 4 axle 53. Depending on how your bridge measures out most max out around 105k gross. PNW = Pacific Northwest.

 

We run 104k on 5 axles…. 40 rears are fine for a tractor if you know how to drive

 

You could just drop the self steer tag axle, it's kinda pointless for general hauling and the frame and drive line isn't heavy haul spec. Wheelbase is a bit long

 

Thanks for explaining.
I’ve never ventured up north always stayed local or southeast. Hell down here the only train we know is on the tracks and if we see more than 3 axles on a tractor it’s a heavy spec. I’ve always wondered about 4 axle tractors with light steers and pushers and what they used them for. Makes sense

 

Another use for them is when you operate in an area with "frost laws." When the ground begins to thaw up north, the allowable axle weights drop significantly until the thaw is completed and the ground dries back out. Having an extra axle on the tractor and trailer can change your maximum gross from 60,000 back to 80,000, depending upon type and placement of the axle(s).

 

Didn’t know that either. Thanks for that!

 

It’s definitely not a heavy haul truck if it just has 10 speeds .
