I’ve just read a story about an electric truck transporting rock from a higher elevation quarry in Switzerland down into a valley. The interesting thing is that the regenerative braking going downhill in the fully laden truck produces enough electric energy for it to be sufficient to power the empty truck back up the hill.
I don’t know about the newer trucks, but the old T282 Liebherrs do the same but the braking in them are pretty garbage. You need to really be on the brake for awhile before it even starts to do anything!
That’s not possible ? Or is it ? So your telling me that Haul truck could run forever as long as it’s battery and regenerative brakes keep producing power minus flat tires, and other things that can go wrong
@@Diezeling it has more mass coming from the top of the mountain, more potential energy (theoretically) than it would need to go back up the mountain with lower mass. Of course a lot of energy is lost in regenerative braking, friction/heat, etc, but under the right circumstances with high enough efficiency it’s definitely not impossible. It’s not that it can run forever indefinitely. This only applies when there is the same amount of energy going into the system via the regenerative brakes on the way down as there is leaving the system when it drives up the hill. It only works when it descends with more mass than it ascends with. On flat ground or with the same mass both ways it would be impossible.
I love how he's willing to say. "I didn't know...." it's really cool to see him exploring and then being modest while delivering great content! Makes for an awesome and honest viewing experience.
@@AaronWitt Keep doing what your doing. You are on the right track. The content is awesome. I work a stressful job, for me this content is incredible relaxing and enjoyable to watch.
One quick tip and I promise you I'm not trying to be a butt hole but it would great if you'll try this... When you're describing something like those quick connect hookups on the excavator arm. Have your camera man show exactly what you are describing and maybe even have him get your arm in the picture, as you point it out. I believe you'll be happy with the results once you see it while editing. Your channel is just what I've been looking for, great job! I am now a subscriber and I really enjoy it. Thanks for sharing it with us all..!! 👍
Why are you surprised they let you video? You present an accurate and honest program, and are always a gracious guest, always respectful, when on-site with a company. I'm sure they checked out your 'style' and thought you would provide some excellent media exposure.
Thank you for tour of LIEBHERR production assembly Factory. I've always been impressed with the Stoutness of there Machines. don't see meany in my area of US. They reminded me of when BUCYRUS-ERIE built all sorts of Construction Equipment. Saw there massive Track Front end Loader at Con- Expo. in Las Vegas couple of shows back. it was so heavy duty well built machine.
Man I love buildings like that second manufacturing facility. With the entire building working as a tool with multiple overhead & jib cranes unlike a lot of buildings you see that just act as enclosures. The power of Pre-Eng 😍😍
Electric driven earth moving equipment is not particularly new to the mining industry and if I recall correctly have been in service since the 70's. Great video gents.
Just discovered you guys. Really cool vicariously experiencing this place through y'all. The scale of some of this equipment and the amount of raw material that goes into the production of these machines is mind boggling. Looks like you're living the dream!
Fantastic factory visit BEST I’ve EVER seen…… lucky lucky people 😀 you know there is also a Liebherr factory 🇮🇪 they make cranes there!! They make soooo much it’s unreal!!! Better built than CAT I’d say 🤔😜
German engineering is in a league of their own. There's a few good docs I've found on German made trucks, firetrucks and other heavy equipment. It's some really interesting stuff
Cool to see! I've done the tour in February as part of a lecture at my university (mechanical engineering) but we didnt get to see the mining equipment factory so this is a great addition to what i've seen there :D
What a cool experience! One of my favorite channels to watch, always awesome content! Would love to check that place out one day, just got my new Liebherr LH50 in at the scrap yard I work at, amazing machine.
Awesome content, The whole electric concept for large machines is interesting cause they either run motors with generators or like the last one connected (typically connected to the grid or large power supply)...innovation is awesome but i would be interested to see the benefits especially where fossil fuels are still used for the grid
As a crane operator i can say they are definitely not treated as a crane lol. I can’t tell you how many times i have been on a job getting grilled on all my pre op safety and literally in the background the excavator is pulling shoring or lifting something. I swear they do it for fun when cranes show up lol IUOE Local 12 SoCal baby
I mean not really it’s got a nice long boom that has the best control other than a crane you can swing curl lift a lot easier than putting shit in a certain spot inside a building with 10 ft walls up or something lol but I guess cause you crane guys are so cool we wanna show off when your on site lol like wtf
Great video! I'd love to see the manufacturer of these machines by the skilled workers. Looks like a lot of technical ability is needed to build them. I assume, these machines are too large and heavy to go down a factory line, constructed by automated machine/robots like the automobile industry?
Correct. They still have lines, but there's a lot of human interaction with the machine at each station. They leverage robots mostly for welding and cutting nowadays
I understand that you're not interested in cranes as I've heard you say before, but do you know who builds the most powerful, and largest mobile cranes in the world? At the time you filmed this video, you were at the earth moving complex they have. I've personally had the largest in N Texas at the time on site lifting HVAC equipment into place for the job I was running at the time. It's amazing what that machine was capable of achieving, and to think that it drove on site under it's own power down the hiway some 40 plus miles from the office of the company that owns it, and afterwards removed all the counter weights, and pieces of the extended jib boom is a sight to see especially after the assembled setup in action. People who see it on the road I'm sure don't have a clue as to what they're actually passing on the hiway, are the capabilities it has. I'm sure Turner Construction has photos of it from start to finish on the Collin County Courthouse renovation and remodel job done in McKinney, Texas around 2010 or 11. It's an truly awesome site to have been lucky enough to see, and actually have it doing what I instructed the operator to do. I've had many different cranes on many different sites during my past career of every imaginable type as well as variety of manufacturers. That was one of the top machines to have the pleasure to work with and in my lifetime of experience in my trade.
About those electric shovels they actually runoff of generators that are powered by 16 cylinder diesel engines they have a very huge electrical extension cord attached to them and they drag them around in the mine! Even caterpillar makes those Caterpillar has a electric drive system on there 797 mine trucks
7:23 first time an american sees a quick coupler and you realize how year 1900 the construction industry in america is. Common, rope shovels and no quick couplers? The steam excavator was decommissioned last week..... richest thrid world country....
@@AaronWitt I wanna suggest with this being 100% positive feedback for your channel to grow? Check out 'Tom Scott' youtube channel. I think he has some videomaterial what might help you evolve your channel. He has done this for a while and his content is too explaining how stuff works :) U prolly know his channel already? :D EDIT/ I subsribed to ur channel too hehe
Maybe you already made a video on it, but do you think you’ll be visiting the construction site north of Phoenix Arizona? New microchip factory. It’s a massive project, 12 billion dollars. Supposedly it’s the largest construction project in Arizona.
love your content is a very good look around the dirt world. I think you should invest in camera equipment to get 60 fps on your videos and it will bring your camera game to the next level.
Hey, Aaron that big Electric! excavator... where do you think it"s getting the Electric power from?? Plugged into the wall back at Home base! Do a video on that cause you'll find Big Huge Deisel generators back at the base So Nothing Green about That!!
not really, depends were they get there electric power from. In Germany we have 50% green electric energy. 10 years a go only 25%. Also a Diesel-Electric Motor needs 30-35% less Diesel for the same energy and the Electric Motor with a Diesel Generator needs much less maintenance and breaks less. You also don't need a clutch or a gearbox, which are also very vulnerable. You can also brake with the electric motor without wear and tear on the brakes. With the electric motor break you become energy back. Without a gearbox, clutch and normal mechanical brakes you are even lighter, which in turn saves energy. The diesel generator is also less stressed because it always produces electricity at the same speed. This protects the generator and it also needs less diesel. Ships, Submarines, big mining trucks/machines have been powered in this way for years. A mining company in Swiss have build a full electric mining truck which charges itself and requires no external power. At the moment, however, this only works because it is going up empty and down when fully loaded. by fully loaded braking with the electric motors, it gains more energy than it needs later to start up.
So what do people want to know about these? Keep a pad, give us the numbers of everything you're checking out. HP/KW, capacity, etc. Super cool stuff, but I'd love learn something for having watched this.
