The Peterbilt 579 UltraLoft is one of the most sophisticated semi trucks ever built. Semi-trucks carry BILLIONS of dollars worth of goods, being driven across BILLIONS of miles of highways. Close to 70% of goods being delivered to your door were at one point being pulled by a semi. That’s a lot of money and a lot of responsibility on the truck AND the driver. But this show isn’t called H2B (hat 2 boots), so sorry Dale, we can’t teach the kids about your Steston and your Tony Lamas. But what we can do is dive into one of the biggest, smartest, most tech heavy semi trucks ever to hit the road - the Peterbilt 579 UltraLoft.
Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

  • When you compare weight being moved to miles per gallon a semi weighing 80,000 pounds at 6 miles per gallon is 80 times more efficient than a vehicle weighing 5,000 pounds getting 30 miles per gallon. 6 divided by 80,000 equals 0.000075 gallons of diesel per pound per mile. 30 divided by 5,000 equals 0.006000 gallons of gas per pound per mile. 0.006000 divided by 0.000075 equals 80 times more gasoline burned per mile than diesel pound for pound.

  • You should have mentioned the crazy pneumatic braking system too. Bitches love pneumatic braking lol. It uses a "brake chamber" which is a hard steel shell with a "bladder", aka a diaphragm, with a steel plate attached to a pushrod and an extremely powerful spring sandwiched inside and locked together with a metal clamp that has a bolt and tensioner to keep it locked closed. (There are more miscellaneous parts that I'm going to skip) At the open end of the brake chamber there's a tiny hole with a metal pushrod sticking out. This metal rod is attached to a metal plate inside the brake chamber and can be actuated either inwards or outwards. When you add air to the "bladder" inside the brake chamber you push the rod outwards. It inflates and compresses the plate attached to the rod and behind the plate is the powerful spring which gets compressed. Since the rod gets pushed outwards from the brake chamber it pushed against a metal extension lever which is mounted inside of the "slack adjuster". The slack adjuster has another rod mounted through a horizontal position. When this rod that's attached to the slack adjuster turns it rotates a lever device that pushes against the brake shoes and forces them to engage the brake drum. I skipped a bunch of little parts and some connection points but that's the jist of it. Air added to the brake chambers releases the brakes and enables you to drive. When you pull the air supply knob and prevent airflow the strong springs automatically compress the brakes which is how they "park".

  • We can also slide the 5th wheel forward or back, same with the trailer tandems to distribute the weight between the axles. Some bigger companies have done away with the air drop suspension due to inexperienced drivers high hooking the 5th wheel and smashing the reefer (refrigeration unit on the front of the trailer) into the tractor or making tight turns and tearing the bags.

    Mandar PundMandar PundPrije 6 dana
    • Technically they are simply "tractors" or "trucks" ment to pull semi-trailers. The trailer is called a semi-trailer because of something to do with no front axels. But the name "semi truck" is referring to what it typically hauls, not the tractor itself.

  • Cool vid mate 👍👍 I live in Western Australia and drive road trains for a living. We cart anything from 160 to 220 tons in quad road trains. That's 2 single trailers with an A & B trailer behind it which has 86 tyres, thats for a bogie drive otherwise it would be 90 tyres for a tri drive truck. The super quads which are 4 single trailers have 98 wheels. Many companies are now moving into the big super quads as they hwve a bigger payload at 220 tons. I've also drove quad power trains that have 2 x 750hp engines. One in the truck and one in the 2nd trailer. The power trains obviously don't go on public roads like the quad road train. From memory we used to cart about a 750 ton payload, that's 1.5 million lbs. These trucks are ruffley about 4 metres tall and about 75 meters in length with the tyres about 1.5 metres tall. Would love to post a few photo's here but unfortunately I can't.

  • Dude. Im sorry but you gotta do some more research, ALL SEMIS have whats known as Air-Ride suspension to reduce the stress on the leafsprings. Also the air tanks in a semi are no less than 130psi and no more than 140psi. And thats for the primary and secondary tanks. The trailer suspension in itself is pressurized by the same system usually the auxiliary tanks because they too have leaf and airbag suspension. Also, cb radios.... 1 OUT OF 100drivers use them. Its kinda sad 😥 😞 also. Most semis on the road are automatic transmissions which is stupid because they start at 1st gear and go thru all the gears when in a manual you can start in up to 5th depending on your transmission and weight. Id know because i drove a peterbilt 389 18 speed tanker :p
