Looks to me like the truck has planetary final drive axles. If you look closely near the end when the camera pans by the rear axles you see the hub. Takes a ton of stress off the driveshaft and puts it into those hubs.
@Eff yore Feelings if he is real smart and educated then sensibly she will have a career of her own and will be independent & not reliant on anyone to provide for her.
@@operatorowen I don't know much about USA trucks but I think that's to low an power for that load. A normal European truck has about 420 average. In most countries we also don't have much steep slopes like this.
The main reason that the older diesel (semis) rolled coal was due to turbo lag time... coupled with the fact that the older turbochargers were Not as efficient in compressing air as they are now. For the most part, diesels in semis, Or any truck for that matter in the US and Canada.... did Not see turbocharging until the early - mid 1970s, and up until they started putting turbochargers on the four strokes... the little 2 cycle GM Diesels (Detroit Diesel after 1965) consistently walked all over the NA (Naturally Aspirated) four cycle Macks, Cats and Cummins... especially on the grades. Anyone rolling coal today.... mostly idiots with diesel pickups, are just showing the world that what they have is a complete mismatch of fuel and Air ratio, with a turbo that is incorrectly matched for the amount of fuel delivery.... while also giving the EPA a good reason to pass even more stringent laws... regulating such "upgrades" on diesel powered pickups... like we don't have enough regulations already!! Did anyone else notice that after all that extra strenuous pulling on the drive train getting up the grade in this video... that the video ended, just as he bottomed the low-bed out on the crest of the hill??.... locked him down, good and solid. Also, that KW has Planetary rear drives, definitely set up for heavy haul in regions with hilly terrain.
_"The only reason that the older diesel (semis) "rolled coal" was due to turbo lag time..."_ Also, any diesel engine can roll coal - modern or old - if it has a stuck injector.
You're confusing DEF with DPF. DPF is Diesel Particulate Filter and does indeed resemble an oversized grenade in the exhaust system. It either has to be regenerated with heat OR taken out and cleaned. DEF is Diesel Exhaust Fluid and is Urea injected into the exhaust to reduce NOx.
I reckon the clutch is having no more difficult a time than it would pulling away from a stop on a flat road... It's everything after the clutch assembly that would be sweating, surely!
Happens more often than even some drivers who did similar realize. I recall a time when I wanted to get to a prime camping spot. I was driving a '71 Chevy 1 ton PU 2WD loaded with a 10 ft camper and gear GVW 9,000+ Lb. Stopped at the top of a 25yd steep ruff downhill down the last bench to the river to take a look. I elected to try it but GF and her daughter chose to walk rather than ride. Put it in granny and went down thru a big whoop in the middle a bit faster than planned lifted both front wheels and landed hard in time to stop and turn before swimming. Girls said nothing and we camped over the weekend. Sunday PM when nearby camps were leaving one of them came by in a 4WD Jeep Wagoneer and commented on my 2WD, asked if I wanted a tow out.Told him no thanks I got in and we were planning to stay till Wed and I could get myself out. He left shaking his head. Wed came and we packed up and left. Again the girls chose to walk. I took it uphill a bit slower and powered out but noticed some frame twist during the process. Got to the top, girls got in and all they said was " not bad you only got one front wheel off the ground 3 ft this time". I proceeded 40 mi home. I noticed some strange performance when shifting gears on the way home and next day checked things out under the hood. I found I had torn one of the front motor mounts completely apart (The rubber) and replaced them both. That was not the last time the torque of that HI performance 350 tore one loose either over the years. That big heavy camper provided me lots of traction but traction combined with torque and a lead foot put extra strain on the engine and trans mounts, U joints and the driveline center carrier bearing. Still all in all a very Tuff truck I drove for 30 yrs.
Bro I am amazed/impressed that the chassis didn’t bust and have the engine just go flying out under _that_ much torque like, holy carp. Not to mention that big rigs are huge in on themselves but next to that crane it was hauling it looked kinda small. Incredible amount of power. “The Little Engine that Could”
Must have been in granny low deep reductio!!! I gone up steep Hills overloaded in my 6 axle dump truck and felt like it was going to pull a wheelie you could feel the frame flexing but never seen anything like that amazing
Nah you would have 12 blokes along side pinching the wheels. I've seen the crap they call tyres over there. And I wouldn't use them to hold a tarp down never mind put them on a truck..
...is the correct answer. Look at the side view at 0:50- it is actually behind the bogie CL. Maybe he was short of traction earlier in the journey, and forgot to slide it forward when reaching the tarmac?
Looks like a Goldhofer trailer with a double drop bed. It is hydraulically adjustable both in the rear axles and the gooseneck. He should have no problem.
@@wcollins7557 Maybe, just maybe, one would know how to adjust it correctly? I'll note that you replied to a comment that stated "where you know it belongs", which probably should have been written, "where you should know....". Point was, it's pinned incorrectly.
@@dwmdwm4607 I'm nowhere near sure that I'm right, and I have never even held a CDL, let alone driven something like this, so it's fine if you don't want to give me any credibility. I said what I said because a driver that delivered something for a former employer of mine that was permitted for both over height and over weight told me a little about the process. He said that before he was allowed to leave the yard, the state DoT agency sent local law enforcement to weigh each axle and be sure that they were within the limits on the permit the company had bought. Obviously this would be done on flat ground. I suppose you can berate this driver if you want to for not readjusting the slide to climb the hill, but it seemed like he knew what he was doing.
You can see at 50 seconds the turn table is directly over the mid of the bogey, definitely should be forward.. I suggest that shear good luck got him over the climb from that point of view, considering he had no control over the steering.. However he did have the correct gear..
Always keep the wheels pointed straight when you lift those front wheels up, unless you want to destroy your entire front end when the truck comes back down
Wouldn’t go anywhere without power. Yes gearing made it move, but these trucks have about 3,000 newton meters of Torque. A Ferrari has about 600 newton meters of torque. So a Ferrari with this gearbox would not be able to pull that MASSIVE load up hill. Or down hill safely
@@chris77777777ify Wheel torque can always be increased with the transmission. Horsepower can not, a Ferrari engine with a gearbox built to do this would pull the same load.
Not a show of great power but improper loading, my garden tractor does this going up a hill with a flail mower and it has 27 hp... he either needs a dolly or another unit in front
It's not so much about trying to make it on time as it is about trying to make it up the hill. ;) I've done the same thing with a 4wd tractor pulling a gooseneck load of logs up a steep grade. I two wheeled up at the top. Not very fun. This driver has skillz. And yes, the rig has power but also stupid tough parts.
I'm going to say that he slid his 5th wheel all the way back, just to make this video. I drive truck for a living too, that's what I would do. Just like those school buses that pop wheelies all the way down the 1/4 mile strip, the engine is in the back, plus just the right amount of ballast weight 😉
why would it not? Clutch is experiencing no more torque than the engine can exert. And the very high torque on the wheels is a result of speed reduction in the gears.
brandon8968ford You can do the same thing riding a bicycle up a steep grade. Th front end will be un-weighted and easy to lift off the ground.,just a matter of physics.
+Sideways Horizontal Distributed power works for the rail industry 24/7.... adding power to the middle or rear gets weight over hills better than more locomotives yanking on one end And I live near a spot where super large loads are parked and staged frequently. Pusher trucks are common with those super heavy loads. I guess those specialty shippers should book a trip to Oz with me?
The rigs I see down here are around Houston... usually huge tank/pipe assemblies for chemical plants or refineries. The ones they park near my house for staging usually have nearly a hundred tires under them. The pusher rig is clearly for control... including maneuvering around turns.
@@danlimbaugh3629 not really. The don't use a "pusher" to control around corners the control for the tires on these types of trailer can be in a few places; rear of trailer with a man helping, cab for the truck hauling the load,all and a chaser vehicle. If a truck is attached to the back of the trailer its there to help brake as it needs to slow down or going down hills. There are some cases to where they will help push but very rarely will they push. The rear truck won't even touch the steering wheel.
That hill burnt 15,000 miles off that clutch!!!! Great driver,didn't try to touch and go for steering,wide road,just let her eat!!!! Love watching professionals work!!! Everyone talking about the trailer bottoming out... Not gonna happen with this trailer. Look at it,it's a hydraulic self leveling trailer. As it crests the hill the reat axles hike up and keep the center off the ground.
Has less to do with power and more to do with the relationship the angle of the hill has on how much the front of the truck weighs to counteract the torque.
