It must be a stagering weight. Hard for me to believe a rig that long can spread the load. I'd guess little weight on axles not near the load.
Looks like they need more gravel to level up the median, then make the turn. Massive weight on some tires, could fresh, soft stone support that weight?

Good thing they didn't have to do a turn like that with the 820 tonne vessel longer than a football field. I wonder how the weight is distributed when you have tires way past where the load is too?

I see rigs with very many axles set up to evenly spread out the weight, typically hauling giant transformers.
This seems to be a simple beam frame, I'd expect it to bend in the middle if each axle carried equal weight.

The 820 tonne vessel used 936 tires counting the trucks to move it. Need a dozen people or more just checking tire pressures! I'd guess they can adjust the suspension to spread out the load so the nearest tires to the load aren't taking all/most of the weight.

Most are equipped with Stemco TPS inflation system
I'm not an engineer. I see a vehicle hundreds of feet long, place equal weight on each axle, wouldn't it bend? I can't think of a flat place I've ever seen where it could support with all those wheels unless they all had 6 feet of travel vertical. Then I think of beam flex, to me it seems some axles couldn't reach the ground, others carry it all.

That's why, normally routes are engineered before hand.

Shipping by rail is better yet....... :)
Well, not necessarily. Shipping by rail is usually a nightmare. There are often difficulites in loading, tieing down the load, size restrictions on rail bridges and tunnels, and unloading issues. Back in the late 80's, I was in charge of shipping a big O&K backhoe by rail from Texas to Miss. Then I shipped some B70 belly dumps from Montreal to Texas. All of these shipments were logistical nightmares. I vowed to never again get involved in a shipment by rail, and I have not done it since. In would pass on using rail.

That first photo is in a rail yard, unload/reload. A boiler built by Victory Energy in Oklahoma,
not far from JY. Don't know the coast of that move but it was a expensive 47 miles to
Lyons Ferry on the Snake River. Now the odd part--Union Pacific has a track that went within
a hundred yards of the straw plant that boiler was built for, instead it came to Walla Walla first.
A track that's rarely used. And the total disaster that ensued with that plant. A plant to boil
wheat straw into fibrous goo to make all sorts of food handling containers--right up to
insulation. Totally defunct--the whole process design and boiler couldn't process enough material
in a 8 hour period to make a few dog houses. Investors poured millions into it--it's been kept
on the hush hush but lawsuits out the butt is what's going on. A total DUD.

You can see the track in back ground

That above is an example of the low level brain trust in the country. RR going right by but it
had to be hauled 47 miles. There was a area to off load just out of photo on left.

I only see the engineering side, rail can take some heavy loadings.

Your feedback on the office side is good to consider.

It's a shame the system is not more interconnected for easier hand offs, more expedited service.
