As a person who has seen someone miss the "timing" of the downshift and get locked out of the gear (scratching it and can't get in to sync in)......... and the catastrophic aftermath of that on a hill i can say it is a "big deal".
@@Moola93 “Double-clutching (also called double de-clutching outside of the United States) is a method of shifting gears used primarily for vehicles with an unsynchronized manual transmission, such as commercial trucks and specialty vehicles. While double clutching[1] is not necessary in a vehicle that has a synchronized manual transmission, the technique can be advantageous for smoothly downshifting in order to accelerate and, when done correctly, it prevents wear on the synchronizers which normally equalize transmission input and output speeds to allow downshifting.” -Wikipedia While this method is efficient and correct (and exactly what I was taught in school back in 1994), it has become outdated and considered to be rather unnecessarily tedious by most drivers. After I got my CDL and went to my very first job, I was told to forget what I was taught in school and to “float” the gears instead. It saves wear and tear on the clutch as well as your left leg. The guy who taught me really knew what he was doing and I’ve been shifting that way ever since.
My son is a trucker ! 30 years now. They get him in the winter to run all the heavy loads. They keep him in the mountains because he can handle his rig well.
To let a chassis twist like that, it takes quite a bit of power or energy. So when a chassis twist like that, you loose that power or enegery. And I think it would be more helpfull to get that power or energy to the ground, in stead of twisting the chassis.
The first time I ever drove a tractor it was a 1989 Western Star 325 Cat. The nose on that thing was like looking down the length of a pool table but I must say fully loaded 80,000 lbs this machine could run 85 mph upgrade. My first day driving was thrust upon me by my boss who was in the driver's seat and he says you've been with me for a year ( I did everything, gladhands open doors crank up/ down landing extra set of eyes and I did all the repairs and maintenance.) He says when you going to start driving. I shrugged and he got out of the driver's seat and went into the sleeper leaving me to decide whether to jump behind the wheel or die I guess. Greatest day ever.
@@TherealHughman Because the gearbox is fixed at the front while drive wheels are fixed at the back. Leaving a gap between the gearbox and drive wheels which are connected by the propshaft which produces tremendous amount of stress on the entire chassis by twisting it in the direction which the propshaft spins at. The resistance from the drive wheels wanting to go backwards because of gravity when the truck is on this angle and the torque of the gearbox pushing to go forward are fighting each other at the propshaft which is central in the chassis. This is also why propshaft failure are very common in trucks and actually needs to be replaced very often, its the biggest stress point in the vehicle, this is why Soviet trucks and Tatras used two gearboxes and two prop shafts to reduce the stress on it.
Это не звук двигателя 😁, а прямых выхлопных труб, если поставить стандартный бачок как на советских машинах то звук станет соовсем другим и не скажешь что это американец😉🖐👈.
Flipped to driveaway and decked loads from trucking. In 24+ yrs I've driven pretty much everything except Scanias including new fire trucks. Pete+KW get all of the love. Some love Volvos. But I've always loved Western Stars. This is one of the reasons. Even thinking about getting into log hauling now. And this driver is part of the reason. No room for some of the "drivers" we have now trucking or automatics doing this. Hat is off buddy. That shifting is smoother than synthetic 80/90. Universal sign for good pizza smooth. 👌👍👍 And this is on a decent road. Imagine pulling these loads out of the bush on dirt accesses wet or snapping a drive shaft or frying the clutch middle of nowhere. Very impressive!
This takes me back to my younger days hauling logs in Tasmania with an R600 flintstone Mack. Its a bastard to get old, you know you should have appreciated your youth and strength more.
Sure it's bastard. Very bastard. You don't really think it will happen to you. It's better to live your youth, don't worring too much about the future. But one day you wake up and that future has come, you'r getting old.
Probably in Michigan or Canada. In winter they pull insanely heavy loads that would make my 95k load on 6 axles look like childs play. Also, this guy has a center mount loader, probably his own rig, drives under way worse conditions then any OTR driver, day and night. He's probably pulled that long hill many, many times. I respect those guys driving skills. Theirs is a brutal job, sitting on that centermount, minus 30 or 40 degrees, wind blowing, loading their truck, securing the load etc. I'm glad it's them and not me anymore. A million things can go wrong.
Listen to the Jake he's going downhill! 🙄 Seriously your seeing a deception thinking he's going up hill, no smoking stacks to show he's on the gas too🙄
There’s a driver that knows sometimes it is handy to use the clutch on occasion. Any driver that says you “NEVER use the clutch except stopping and starting” has never driven a truck loaded heavy enough on roads bad enough to know how to pull off a high-pressure downshift that needs to happen fast or you’re gonna end up stalled on a hill you don’t wanna be stalled on.
Y’all are hilarious especially the 1939 driving style of double clutching which IS NOT A THING. I’ve been driving for 25 years with almost 2 million miles behind me both on and off road. I ain’t NEVER touched a clutch except to start off because I know how to shift. Yeah I scratch gears once in a while but not often. Oh and by the way I’d put money on that truck having an automatic.
I've been plumbing for 35 years, and I can honestly say that is an awesome tractor-trailor !!! And judging by the comments, he must be a gear jamming double clutching professional driver !!
Never been a trucking, but it is very clear to see that this trucker and that machine are absolute top notch. The driving was superb and spot on. About as perfect as a man can get. True skill and a real joy to watch. Love that truck and the sound if makes. Had to watch it a dozen times with the sound up. Beautiful work.
My dad used to do that but with a twin stick on skinny logging roads in the mountains. This man here has established himself at the round table of excellent truckers.
where i live on the coast of washington log trucks are an everyday thing on the roads. not much snow out here but lots of rain and mud in the woods. Love the sound of a loaded truck moving thru the woods on steep hills!
Привет!Мощность ВЕСТ- СТАР- West Star - (я неумею по - английски) ОДИНАКОВЫЕ с другими Петербилт,Кенворт,Фрейдлайнер,Форд и еще другие ( неважно)? ЕСТЬ в США РАЗНЫЕ МОТОРЫ С МОЩНОСТЯМИ? СПАСИБО!
@user-vk6pz1bx7p I am not an expert but Caterpillar, Detroit, Cummins, Packard, and others are on the market. These could range in Horsepower from 400hp upto 600hp. Gear ratios can be custom purchased for the customer requirements. These trucks specified for logging are built extra heavy duty and powerful. I hope that helps. Peace! From Ohio, USA. ☕️👍🤓👍☕️
*This one* is not an everyday sight on the roads. Too tall, wide, and heavy. This is a woods road, and I'm guessing it is headed to a nearby mill.? Or a woodyard to unload at, where smaller loads can be hauled on public roads.?
@@frankmarshall9245 According to building movers, the average American house (without concrete foundation) weighs between 40-80 tons. - Google That truck doesn't weigh anywhere near 160-240 tons.
Before retiring I love trying different trucks out. Always enjoyed pulling a set of doubles around. The log trucks I never and still never will have the desire to try them. That is a top heavy load and there's a lot of weight on the back of that truck. I'd love to know what engine is in that tractor. You can tell it was built with lots of torque. Every time he or she got off the accelerator you can just see the tractor twisting. I have nothing but respect for people that do that kind of work. If it wasn't for the men and women willing to go back in the woods and bring that out we wouldn't be able to afford to build anything.
Everything that was moved by a truck was made or mined by another human before it was trucked tell them all thank you as well and don't forget all the people that works hard to buy those products or they wouldn't need trucked so thank them as well man self centered are so stupid
