Hey Guys,

this is is a beast of an EV!
And it never needs to be charged!
check it out ;)

eDumper

I would love to have one.
Just for show in the front garden connected to some pv panels.
And for traffic jams. :D
 
It's actually a little misleading in the title of the description the race car driver gives. He states that it never has to be recharged. However, lets take a look at his own numbers:

They start off at the base of the hill with 90% SoC
The climb the mountain empty, but still uses about 10%, so at 80% SoC
Then they brake regen on the way back down the mountain and reach the base with, 88% SoC.

Now that's a 2% deficit from my point of view, and repeating this trip 20 times a day would be a loss of 40% SoC.

He says they reached the bottom with 88%, but I do wonder if they were "really" at the bottom when he made that statement and the last bit of coasting they did finished off the 2+%. They don't make that clear.

Personally, I think they weren't in fact all the way down based on the last few scenes from inside the cab.
 
Race car driver...LOL, my fantasies where immediately running wild.
Road around amsterdam for example, me driving.

If i look at the big rigs and cranes at my work, i can't even imagine how much power that thing must have to go up hill.
We are talking about somemassive badass electro motor(s).
Some serious mass that must be moved around.

I also suspect that he is not only charging at his brakes but also there is some alternator/dynamo?
If they lose 40% SoC a day,how do they charge that beast, cous it's not like a tesla or something.
I do think, on works/mining, like those that they do, go for 24/7 and not just a 8 hour working day with those machines.
I suspect they have a onboard generator like those dragliners have, but a bit bigger.
Some dragliners use a dieselgenerator topower up the hydraulics and there driving e engines.

Some cranes that runs on a power cable, has a electric hoisting motor where you can park your car in it.
Not talking about 380v volt but some more serious volt, the biggest one i saw used a 10kv cable.
I don't know the precise details, but i know it was a 10kv cable.

Interesting, i hope i can find more about this e beast.
Good point Korishan!

I also don't get the Values in this video, but the company states that this beast produces ~77MWh per year which is fed to the grid then.
But not only the size of this vehicle is hugh, look at the amount of Diesel which is saved with this, over 50000L per year.
The first so called energyPlus vehicle.
So as a result, we just need to drive downhill only, then our energy issue is solved :cool:

But apart from that, also take a look at the construction of the dump body. It's not a fixed Sheet surface, it's flexible.
Tie rods keep the sidewalls together.

Apart from that, it's not even the biggest beast.
Look at this interesting videos of the build and the specs of a Liebherr Mining Truck.

Wonder how many Battreries would be necessary for this as an eDumper....
 
yesterday at the constriction site they where poring concrete.
Usuallu it akes a lot of noise...but.....

It was silent....when it was to its unloading part.

The give me a sneak preview of what theyare buying now....
FULL ELECTRIC....radius 500km....300ish miles with FULL load..
9 cubic meters of concrete or 27 cubic foot or 22.000kg of mass!!!!!!!!! Without truck of course!, total 60.000 to 70.000 kg!
**** me....

Wow! nice. 300 miles for a concrete truck is about right. They make it just before pouring into the truck hold and then book it to the job site. 150 miles each way is a good distance.

Definitely impressive!

I see that construction trucks will become more and more electric as they don't need to travel as much/far, they can be charged up in the time they sit still reloading, and the amount of fuel, maintenance, laybor savings will be huuuuge


Did some research on these. The main drive train is still diesel ran. So when they drive, they are still using a diesel engine. The electric portion is what drives the tumbler. No more hydraulics. The main engine shuts down while they are dispensing the concrete. On one of the videos they said that there was a diesel generator that provides the electricity to run the electric motor to turn the tumbler. Not sure if that includes the dump action or if that is still hydraulic action (considering the weight of a fully loaded tumbler, it's still probably hydraulic and ran off the primary engine; just guessing on this part)


Update #2
Here's the video for the above that 100kwh-hunter posted:


The PTO is 100% electric. Saves about 1/3 of the daily fuel costs. Looks like the electric motor turns the hydraulic pump that runs everything else. They did several close up shots of inner workings
 
I was really surprised when i saw them, like a kid's first time in a candy store.
I don't know the full story of the 100% electric one, but they told me that there was no diesel engine whatsoever anymore.
Probably they will use those ones in cities and close to the cement plants, there charging stations must have a minimum of 16 hours to reach full charge.
When they come with the 100% electric truck next month(probably jan/feb), i can drive a small piece, if there is time, and i am there.

Nice video, was recorded in the Netherlands, i will also dig into this, more and more is converted into electric.
 
Interesting. The video is from 2017, so maybe they've made upgrades since then. Which would be great! More electric on industrial equipment will help drive the operating costs down and in hopes also drop construction costs (unless the owners are greedy and keep the prices high for a higher margin).
