Magnificent Pulling Power from MAN Tractor Unit

[Debater Slayer]

In this video, a MAN tractor unit navigates an unpaved stretch of road that includes a tight hairpin turn and an uphill incline, all while pulling 80+ metric tons (assuming the Kleemann rock crusher it's pulling weighs at least 60 t-65 t).

If the rock crusher in the video is one of the larger Kleemann units, then the truck is probably pulling at least 100+ metric tons (including its own weight), yet it still effortlessly handles the off-road, uphill climb as well as the tight turn. Astonishingly impressive performance and torque from that engine!

A couple of particularly notable highlights are at 3:18 and 4:20, if you don't feel like watching the whole thing.

All wheel steering on the trailer helps but woe, what a truck, what a driver...

What I found to be most impressive is how the 16 wheels at the back of the trailer turn independently from the front wheels of the truck. With the trucks turn to bring the tail into line with the truck, or counter to the front wheels to allow more clearance around an object the truck is curving around. Well thought out.

There was a tv program about a heavy haulage company in the UK who specialise in moving trains by road. I watched a couple of episodes but it became so same same i gave up.

Note the guy with the control for steering the trailer wheels following the trailer around a corner .

Yes, tips hat to these guys

Nerd !!!!
Gearhead !!!!!
But a minor correction. Torque is not what matters in trucks
(or any vehicle). It's horsepower, which is proportional to
torque times speed. The transmission can gear down any
engine speed (thereby multiplying engine torque) to the wheels.

This is a moving job that a friend of mine tackled in Chicago.
(He's a naval architect. His company specializes in marine
heavy rigging, lifting, & moving.)

Another heavy hauler video has a 108 wheels on the ground.
It has one push, & one pull tractor handling @700,000 pounds.
(At a rest stop, I once saw a rig with 132 wheels just on the trailer.
It had no tractor or load with it though.)
