Just read both are in a Museum. MIGHTY. Thank heavens for the invention off volume knobs %)

When men were men......the guy driving the open air cat,I can't imagine what he had to endure in that weather....

There was quite a bit of discussion on these engines and the contractor some time back in the steam community. As I recall, this happened in the mid 60s and the engines were rebuilt McKennas. The machines were beefed up and had a much increased boiler working pressure along with over bored cylinders and other beefed up running gear. The Contractor was Ottomeyer. This was the job these engines were prepared for and likely the last work they did before being retired and I believe one set of them are in the museum. A few years back one of those pictured was sold at Cheffins auction house in UK, a major auction house that specializes in high end collectables and steam engines. Don't know the disposition of it today, but it brought serious money at the time.

I bet my right arm and muscular hand (that sometimes pleasures me beyond my dreams) that none of these Macs are chinese built.

My grandfather was the foreman. He was only 30. I spent every summer with him in his 70s and 80s. He was born in the middle of no where Montana. His first 7 children were born in Alaska and the other 6 were born Montana. He operated a ranch in one of the harshest areas of Montana. He was quite, kind and patient with me. He taught me to shoot, to ride a horse and most importantly how to work hard. He had a bulldog tattoo on his shoulder. He also served in WW11 in the Maritime Service bringing supplies and troops to the Pacific Islands. He passed away at the age of 75. He had over 30 grandchildren and 5 great grand children when he passed. Thank you for sharing. Remarkable to think of what they accomplished!!

Meanwhile the Australians are beating their chests about they're road trains. Pffft.

Pre trip take a day

Very impressive.The brakes on those cats are bad ass evidently. What is an engine 225 ton on a dead pull like that

Dam ! I Wish MACK made a Pick up Truck !

Id love to know how many of these trucks are still around and where they are setting at not being used anymore. So far ive only ever seen one video on here with one still setting. I also wonder how many got left under water

Beautiful trucks.

Cool old video thanks for posting.

21:17 “You tell him of the bulldog conquering the Arctic” The native replies, “Many dogs, yes.”

Super cool video!

What powers that?

The only true part of this b/s is th truck falling through th ice under its own weight... If it wasnt for th dozer dragging it along the track, this would of been over in 30sec. No more of DIM TIM.... for me...

My dad helped on this job, he’s since passed away but this brought back some memories. He had been on the road for so long we waited on the side of the road when the load passed just so we could wave hi to him.

For few years, Mack worked with Saurer Switzerland, buying then the Saurer USA department. Saurer was also an amazing brand of quality, trucks from the '70 are still around working none too gently with the same pieces that they came out from factory. I'm glad that Mack is still around making quality machines at least.

This was all filmed in Canada 🇨🇦 our DEW line, not the USA 🇺🇸

At 17:54 he caught him a gear...

That's back when Truckers had Diesel for Blood

And they never had to stop for def.

WONDER FULL ..

I recently found one of these fat trucks in Kirkland Lake Ontario.

I worked across from Vancouver Island in the 1970's at logging camps called Namu and Nikite where the smaller trucks like the Mac and Hayes HDX had 12' bunks and would hall 100 tons of woods - the Bigger Trucks P 16 and one camp had a Euclid 85 ton rock truck with 18' logging bunks - huge trucks 150 tons of wood coming out of the bush down hill at a 2-3 per cent grade - Every other truck would stay off the road at pull outs - all were in contact by 2 way radios as these Monsters could not stop - huge water tanks just to keep the brake drums cool - At the dry land sort the logs would be sorted and placed in 8' log bunks - strapped with steel wire and then pushed into the water for the boom boats to push over to the self loading log barges that would go to Asia - Trees like a 5' to 6' yellow cedar that were 40' + long the buyer would pay $8000 for this one log to be made into furniture in Japan - Now , the big trees are left and taken out with large Helicopters like the Sikorsky Sky Cranes - Coulsen Air Crane in Port Alberni also has the MARS WATER BOMBERS that hold around 6000+ gallons of water to dump on Forest Fires - I was a driller / blaster on the Tank Drills in the Good Old Days -

Had these trucks been powered by steam, they would have been the greatest workhorses the world had ever seen. Friend of mine perfected a steam unit the secret being controlled superheat and a very efficient engine. It was installed in an old Ford Falcon, taken to CA, demonstrated to politicians and vehicle builders successfully. It was the lowest emission engine in the world. They didn't want to know about it. I could be excused for believing the quest for clean air was a political hoax. .Govts. just kept changing the goal posts to suit the vehicle industry. Steamers can be thrown astern for braking and the more heat the better they like it.

Quite an euphoric music for watching such massive environment destruction...

Jak ruskie po huj to tyle ładować

Mack trucks 🚒😎😂😂

Snowrunner guys here?

Case made 180 hp steam tractors, I believe.

I restored a 730 comfort king, looks like new, it had cen pe co oil in the engine all its life, no blow by or anything coming out the exhaust.

Amazing Historical Video - somewhat ruined by the music - Germans always liked Mammoth Machines .

In scotland we don't have mac trucks but I can still admire the brute strength of these awesome truck's and these pioneer truckers what a job what a beautiful office nature at its most beautiful

Now that’s a big boy toy!!

Tim, that was a great catch. When Winters moves out, They Move Out!!! Great video! Really shows what the unit looks like.!!!!👍👍👍

Nice Rerail. Those 583s are powerful machines

In the winter months they use to turn the radiator fan around throw some old army canvas tarps over the engine and back around the oropes to get a little engine heat cool old CATERPILLARS

You know if this thing went to India, they'd figure a way to overload it.

What's with the music?

Это какой-то ужас!

Ugh… don’t use a finish mower to bush hog..

Vad är det man dikar för ? Ser ut som att man bara fyller upp diket med samma material igen ???

buenas noche tenemos una maquina igual y estoy buscando el manual del usuario para poder operar esta maquina si me lo podrian pasar les agradeceria

At one time MACK was the strongest Most durable truck in the world - well it’s owned by Volvo now- I think that needs no further explanation as their trucks are trash- As are freighliner (Daimler) Peter lit and Ken’s hold on for Dear life - IH is a beast but no ones buying - welcome To America - land of the lost

I worked 25 years for MacMillian Bloedel at Eve River Div. Fat trucks were King

This narrator is a blast....

Powell River where I grew up had a big M & B operation. Logging was one of the divisions. I had many close encounters with these trucks in the back country, scared the crap out of me. Calling mile markers on the radio was the way. Some of the roads where extremely steep, 20%-30% grade. Canadian Aircrane flying above me with a big log was uncomfortable. M & B also had a pulp, paper and saw mill in Powell River that employed thousands of workers, I was one of them. Mostly shut down now. They also had hydroelectric power, two dams and five generators.

This is the cause of global warming and climate change. Chopping down the forests and trees

Seeing old growth on its side being hauled down hurts.
