OK you truckers...

when your 18 speed goes you can have it repaired here


Pakistani Truck. One of my favorite youtube channels. When the dark ages hit be it a meteor or an EMP those people will be instantly thrust to first word status. While us former first worlders starve and grovel. We are so far ahead that we will never catch up.

Those are not coils?
If I had to guess they are Chinese coils, and he either pulled out to finish chaining and tarping, or waiting to unload. I'll give him a atta boy for being considerate, hard to find nowadays.
I don't know. That's why I tagged you. The yellow ends had me wondering.

They look like coils, 2 for 40'000+ pounds total makes them about right size. They put covers on them sometimes to protect edges of steel from tong or C hook strikes. If your waiting in line to get unloaded it is customary to get down to one or none restraints. The plastic is fairly common to protect from rain under the tarp, which of course would never have holes in it, or just put on so you can roll up the tarp and stow it if a chance of rain. He is obviously not rolling down the highway like that in the picture. It might just be a rare picture of a courteous driver.

Apparently, its LESS about the truck and MORE about the trailer to understand WHERE the term "semi-truck" comes from. So .. you folks who drove/drive this truck/trailer combos for a living agree with that answer?

I am running with that answer unless redirected by a professional driver....:)

Lot of words for simple answer.
Truck/tractor carrys half the weight of the gross trailer weight, ie. "semi". A regular tag trailer behind a car, or pick up only carries 10 % of the weight on the hitch, and thus on the car/pick-up.
For example you need approximately 500# on the hitch if your trailer weighs 5000#. Rule of thumb. You can get away with less, but you must have the CG. forward of the axle centerline to make it stable with no sway.
 
Trucks early on were just trucks, big box with a cab. When the box became a trailer making it basically an articulated truck it wasn't a "truck" anymore, it was a semi truck.

That's my story and I'm sticking to it.

While I was nerdin' out on "semi's", i stumbled across Hyundai's hydrogen powered "semi-truck trailer" .. the HDC-6 Neptune. I saw in another thread Cummins' hydrogen engine, as well as newer alt.prop. "Nikola" and "Tesla" vehicles coming.

What drew my attention to this Hyundai was not the hydrogen thing .. it was the design of this rig. And then I read Hyundai's inspiration -- the streamliner Art-deco locomotive design style from the 1930's -- 100 years ago and it's back.

art-deco streamliner locomotives from 1936 and 1938, respectively.

the shape of things come -- and gone -- and come again this time for Class 8 rigs?

Hope it does not need all that skirting to run. The flip-flop mafia will have that ripped off in no time

My read is it MIGHT need all that skirting .. its a functional "grill" for the truck.

article says

"The grill is used around the entire lower portion of the vehicle to increase cooling and maximize airflow."

a related article (source: Hyundai Reveals Commercial Truck Mobility Vision at NACV Show) builds on that by saying:

"On HDC-6 NEPTUNE, the design team took packaging challenges and found new ways to combine both form and function.

Due to increased cooling requirements, the grill of the concept commercial vehicle is applied as the theme across the entire lower portion of the Hyundai HDC-6 NEPTUNE. This creates a distinctive image while maximizing airflow.

The grill concept also integrates the retractable steps, which are cleverly hidden. The combination of both cab over engine and conventional (bonnet) truck formats achieves packaging efficiency and improved ergonomics."

I do NOT know about THIS truck's application of hydrogen FC, NOR how they manage heat. I DO know from a past life that a mobile fuel cell needs exceptional thermal management to work well AND safely.

Hyundai seems to be saying this funtional need for cooling the FC "stacks" was married to a styling choice for a wrap around grill to look "cool" at the same time.
