It blows my mind how many older machines that you all have in Pennsylvania that are still in great shape.

That truck looks like it has been well cared for.

Fantastic work 👍🏻 I really enjoy how you do these documentaries.

There is something to be said for an enthusiasm for your subject that helps. I always think of a kid in a candy store when I hear him talk. The amount of info and the "joy"(?) at being able to share are nice to listen to. 😀

Haha, thanks guys! I appreciate your support!

You guys take really good care of your trucks, our AC drive 830E are twisted in a dozen different directions from truck contacts and large rocks falling onto the deck. Every PM we have horse collar cracks and fuel/hydraulic tanks are coming off for frame repairs. Also looked like your LHS tie rod end grease injector is bypassing.

Excellent documentary once again PA 👍👍👍 Just watching this makes me want to get back behind the wheel of a big dumptruck...

Fantastic look at this gigantic haul truck. Hope you had a really happy father's day!

Thank you! And I hope you had a good father's day as well!

Thanks PAmining for another well done video documentary. This Komatsu 830E is a very impressive haul truck for sure. This truck has been the only really serious competitor to the CAT 793 haul truck. And even though the sales numbers are impressive for the 830E, the 793 series has done significantly better. Without a doubt both the Komatsu and the CAT are top of the line in the 240 ton class.Whenever I discuss haul trucks for mining applications, I always remember the phrase that many people use to describe the CAT 793. They refer to it as THE GOLD STANDARD. To me that says a lot. I’m also a big fan of mechanical drive haul trucks.Take Good Care.

@@PAmining I wrote in my original comment about this video that the Komatsu 830E has been the only serious competitor to the CAT 793. Then I realized that UNIT RIG had developed an outstanding haul truck in the same weight class. I believe that truck was the model 4400. You are probably familiar with that truck. I recall reading a heavy equipment book years ago by a real authority on the subject. The author stated that the UNIT RIG 4400 was about as bulletproof as you could get. Yeah so I just wanted to include that info to be more accurate. And also to give UNIT RIG the credit they deserve. After all that company was the original manufacturer of the first diesel-electric drive haul trucks.They started with the M-64 ( failed). And then they got it right with the M-85. The company also designed and built the first 200 ton capacity haul truck. That truck, the M-200 was powered by a locomotive engine.Take Care.

These videos are always so well done and so interesting. Do these large mining trucks really need that much HP to power the generators for the electric drive systems?

Nice looking truck. That’s a biggin. I think those diesel/electric drive systems are the way to go, so many less components and smooth power transition. Thanks Justin 👍👍

They are excellent but they also have their weaknesses. Electric drive trucks aren't designed for road grades over 8 percent or and heavy water conditions. On flats, they are champs.

@@PAmining That makes sense. I did hear cat was working on D-11 electric and I think they already have some 7’s on the market.

Happy Pappy Day and Komatsu didn't need to tied up with Corn Poppers. God Bless Yall!

I love your videos! What I would like to know is how much the tires cost, the cost for an oil change and how often these big machines need service? I ask because I don't know. Keep up the good work.

They usually get PMed once a month (scheduled maintenance) and tires run about $50k US apiece, depending on the market price at the time.

Excelente vídeo 👏👏👏👍😎🇧🇷

Would like to know more about that resistor braking system . Another great vid Justin 👍

Sure thing! The blower forces air through the girds. The girds are like an element in a toaster. They convert the dynamic brake energy from the wheel motors being used to slow the truck down into heat.

Awesome video as always! Thank you! Do you know what the knobs by the forward and reverse lever are for? One had the rabbit and turtle, is it engine idle speed? Was thinking engine speed would be governed not by operator but computer determining demand.

looks in dang good shape. rebuilt??

7:27 are those traffic light?

@williamhall9204

@catzzzz1450 No, those are not traffic lights. The lights are part of the onboard weighing system. The lights will indicate to the operator that is loading the truck just how much material is in the dump box.This haul truck has 3 light panel that will indicate target weight is loaded or if the truck is overloaded or under loaded. Nowadays you can see most large haul trucks have a digital display attached to the side of the truck. It will show how many tons of material are loaded. This newer system is definitely an improvement. The setup on this Komatsu 830E is probably original equipment when it left the factory.

Is the pin-up an OEM feature of the truck? I didnt hear you comment on it....
