RG LeTourneau was a revolutionary individual not just in the heavy equipment industry but also in mankind. Thankfully, I've had the opportunity to put around in one of those log stackers on a school field trip. I was a sophomore and have to say that I've had the opportunity to be in a loader and a tourna-pull too! I've been saying for years if LeTourneau could do it, there is zero reason we can't today.
My old friend Dwight worked amd went to school fot Mr LeTournea, he had a lot of good stories, i tried to go there but too much tuition for a half broke country boy.
Testing is all about learning those parameters. Topsy makes it look so easy. And with a full load of logs people can’t say you are just hauling an empty box trailer. That is legitimate and completely road legal weight 😉.
That was such an awesome 1st test. What really caught my attention, was when you guys were running down the road , at 85 KmPH, and having a regular voice conversation in the cab. So quiet in the cab without the engine. That was super impressive. Looking forward to more tests ! Great work. 👍
I can't wait for off road winter testing! Electric axles just gives you so much control over traction. And the traction control can be changed drastically on the fly with software changes alone.
Been awhile since I've seen a Letourneau. I think I've rebuilt every component on them when doing my apprenticeship back in the early 90's before the Wagners replaced them.
@@Amanda-ej7pl. I was in the Prince George BC area when this happened around here. I think most mills went to the hydraulic Wagner units due to lack of electrical system knowledge. There aren't too many people these days who grasp the generator and motor set-ups in the Letourneaus. They have both AC and DC systems. Easy for me to understand as a Motor Rewind Electrician, a little tougher for an average Heavy Duty Mechanic to understand. Topsy is actually a simplified Letourneau technology by replacing old mechanical contactors with frequency drives.
@@raywagner8016 wow that actually helped me understand Topsy. My husband does some side work with an electric motor rewinding company. We do service calls so I have a decent understanding of high and low voltage systems as well as mixing AC and DC. I'll be looking for the manuals online to understand it a little better.
Congratulations to the whole team. Finally a real Canadian achievement Tesla can go hide and be ashamed because guys you have achieved something great. Congratulations👍👍👍👍👍
It's amazing how easily those motors pull all that weight. This is the setup they should've been using from the start for the trucking industry. Nice work fellas!! 🏆🎖🏅🥇
Maybe canadian, but not world... diesel-electric trucks have been used in Europe for a a few years now... In fact, there are a few of production vehicles you can buy, as the Volvo FE Hybrid which have been around since 2011.
I noticed that, too. He has a short where he talks about how it's safer to not have airbags because the driver would lose control in an accident when they went off. You know what else causes a driver to lose control in an accident? Getting jolted out of their seat because they weren't wearing a seatbelt.
@@phillip_mcguinness7025I mean seeing that the cyber truck made it at least two videos and it was mostly glued together. Unbelievable topsy could make it a whole month.
I know she's electric but I'm still always shocked at how eerily quiet Topsy is. Great stuff and i love to see it! Some day I'll be rich enough to buy an L500 with the twin seat sleeper cab
Congratulations! monumental accomplishment! boldly driving into the future. when I started hauling logs 45 years ago if you would have told me we would have an electric truck in my lifetime I would have told you not happening. can't wait for the down the mountain out of the bush into the mill episode.
@@markplott4820this truck is about bringing simplicity and ease of repair into this new age of electric trucks, diagnosing and fixing a bunch of cameras sounds like the opposite of that
Love that the truck is passing its tests with flying colors. Its been amazing watching you guys go from concept to prototype to actually testing it on the road. Congrats
@@bd6862you and another guy had the same idea, they said to use a lever to adjust it, i think it a great idea, even more locomotive design influence on topsy
Downhill regen could be configured on the road by estimating the load weight under acceleration. Just measure the speed increase rate for the applied power and scale the regen accordingly. reset the function at every full stop longer than 30 seconds to avoid surprises when unloading =)
Power for days means that you can probably reduce the motor size (or power output) to gain efficiency. I like your channel and your trucks. Please continue.
Considering how little power you used, I'm wondering how Topsy would work hauling an Australian Road Train? The initial pull off the start for these trains is enormous. It would be an interesting test of your truck's capabilities.
@@joshuacheung6518 The largest ones allowed on any roads are 4 trailers and a bit over 130 tonnes. Private roads on e.g. mines can see over 200 tonnes, but I think at that point you definitely need powered trailers. Keep in mind the terrain these run on is pretty well perfectly flat.
@@joshuacirillo7307 they used about half the battery percentage, but in the future they could easily make a super fast charger that you can plug the truck into for the 20-40 minutes while you are getting loaded and tied down. In this kind of work just hauling across town the generator would potentially never need to start.
I love your ideas. I find it amazing how different things are done in different countries. In Australia, the trailers all load and unload themselves and a lot of the trailers have air tensioned straps tom hold the logs down so as any logs shift they just automatically tighten. Love the truck you're making and hope you can ramp up production and put the big companies in their box.
its not silly friend,..batteries with the power of the Suns are on the way. A fully electric vehicle will dwarf the performance of any vehicle before it in Cost, Performance Maintenance and Driver satisfaction by making fat stacks for the O/O
While I'm not a truck driver, I am into engineering, so: I would second another commenter's recommendation for a lever or some other control for the amount of regen. It would allow you to disable it when just coasting on flat ground, and when you have limited traction, but also to crank it up when you want to.
I like this thought. I wonder how much extra work that would be. Surely can't be too bad in the grand scheme of things? I'm just a wrench, I have no idea. Just sounds like a good idea to me.
Glad to see that Topsy is doing great and towing even better! I will be interested to see what the performance and economy differences will be after you get a Scania engine one of your hybrid semi trucks.
Hell yeah, Chace! That's awesome! I know you feel vindicated from all the detractors who claimed things like "It only works without a load" and BS like that! Nice work to all of your team!
Awesome work, guys! Super happy for a successful test! I agree with one of the other commenters that an adaptive “Loaded” regen scheme based on the load during acceleration would be pretty clever, but I’m sure you can’t beat the simplicity of manually adjustable regen for the time being. I’d love to see what kind of power you can recapture with that much weight rolling downhill!
I'm so glad to see you guys are doing so well here! 434k subscribers! Amazing! You guys have a fantastic product and you make great content. I wish you the greatest success!
That description of starting up the load and it just does the job without fuss or struggle reminds me of the first time many years ago when I was driving an electric car and put my foot to the floor to see what it did. It was incredible; there was no increase in noise at all or any sense that the car was at its maximum power except for the numbers on the speedometer ticking up. I've still not gotten over it, and I can only imagine that's a bit of what it felt like for Chase driving that first load.
Great video, super excited to see Topsy hauling loads. I would love to see a little more stress testing. Drive it like an angry trucker, slam the doors, get a little mud on the mud flaps. I know its a million dollar prototype, but you can't baby it forever
I know you haven't talked much about who's pre-ordering trucks, but I'm willing to bet the Nickel Brothers or Belton Brothers are just salivating right now. These would be PERFECT for house moving, especially with a built in hydraulic plant for lifting or leveling out dollies enroute.
Would love to see these pulling 300 ton iron ore road trains in the north of western Australia , especially when in future you could place drive axles on the trailers
Love that you showed the tug test. If your truck was available with a sleeper cap, I would probably start driving again. Such an amazing insight and application. Maybe in five years I'll buy a sleeper from you and start driving again. The visibility is amazing. I'm in Florida, so not very many hills, but still, such an amazing machine. I'll start saving and you keep working towards availability for the north American continent and we'll meet in the middle. Love what you're doing and appreciate your vision. It's a winning design, keep moving forward.

absolutely, electric vehicles will outperform anything else , this vehicle is Globally Foundational. I really hope the rest of My Country catches this drift and follows this example
I think it would be interesting to see the regen set up like a trailer brake controller thats adjustable, so you can turn it up or down based on conditions or preference for the individual driver
The interesting thing is you could build electric trailers with e-axles which could be used to help propel the load, and also to help with regenerative braking (you probably discussed this idea on the channel before). Probably not worth the cost of the e-axles but it would be a cool idea lol
Great video on project Topsy’s progress guys …..So doing some slide rule & napkin figuring , 300 k/w for 180 km...@ 12 cents KW/hr that’s roughly $36.00….. same work done with diesel ,,, rough estimate, 80 litres or about $150.00 ……. Great! …… but what I’m really forward are your numbers when you bring a full weight load off the mountain, I want to see what loaded regeneration wattage is compared to K/W running up the mountain empty ,,,,, I believe those are numbers that will get investors really excited …..good work so far guys and keep the project moving forward

This is my recommendation for the regen braking. Put it on a dial so you can infinitely adjust it. This way it can be perfect for every case scenario.
Tell me what other people think of this idea
@@bd6862you and another guy had the same idea, they said to use a lever to adjust it, i think it a great idea, even more locomotive design influence on topsy

No grant money... Its a crime you guys dont have endless grants.. you guys are badasses!!🎉
Downhill regen could be configured on the road by estimating the load weight under acceleration. Just measure the speed increase rate for the applied power and scale the regen accordingly. reset the function at every full stop longer than 30 seconds to avoid surprises when unloading =)
Some manual control is still good for when traction isn't perfect like in mud, snow, and ice
should honestly just be a lever they can move up like a throttle. Would give finer control when going downhill.
that sounds like a great idea, like the dynamic brakes on a locomotive
Great to see it doing what it is supposed to do!
Power for days means that you can probably reduce the motor size (or power output) to gain efficiency. I like your channel and your trucks. Please continue.
Since it's got dual drive axels, i would think one would shut off of at speed, using 2 only to get the load moving
Most of the time larger diesels are more efficient. There’s no reason for a smaller power unit unless the space is needed.
The initial goal was to have the same HP numbers of a 15-16L engine. With the torque, it may not be necessary to have this much HP.
except Hybrids are UNRELIABLE and break often, require 90% MORE maintenance than BEV.
and you CANT fix Hybrids in the Bush.
@@markplott4820and, depending on where the “bush” is, you might not be able to get a bev there at all.

that initial start is where electric really shines so my bet is on it having no problem whatsoever

Maybe not the most representative data set ever, but still can't beat zero fuel consumption.
Gonna need a few weeks to a couple months for that. When they get in the hills it'll be test time.
they say they got to ~50% state of charge, so based on publically available data should be about 40 litres to recharge.
