What's with this ?

We always used a stinger type dolly like what truckdad posted never had one get away. Sometimes we would use the scraper to stack the dolly unloading over the front of the jeep and pulling the dolly up the Ramos with just the front motor. Sometimes it wouldn't work. Moving scrapers like that is a lot of work but they ride so awesome.

 

Back in the late 80's up until early 90's in Md,.. thats how we hauled 613 and 621 single engine scrapers, using just a front dolly and letting the rear of the machine drag behind on the ground. Never went more than 100 - 200 miles like this. But yeah,.. thats exactly how we did it.

The difference in the second video you posted is that jeep has a power tower on it so you connect the neck back on the trailer then pick up the trailer with hydraulics on the jeep they didn't have that in the first vid so they had to ram it under. I'm surprised they call that a nine axle it's really a triple sixteen and if it was a true nine axle they'd never legal that 772.

 

The guy hauling the 772G, with the trailer he has and a 3 AXLE tractor could gross roughly 246,000. I think most of these units are under 80K empty. Leaves a payload of 83 tons +/-. A 9 axle similar trailer with only 4 tires per axle (commonly called a baby 9) will allow him approx. 208,000. In CA when we say "9 axle" we are referring to the total number of axles of the entire unit including the tractor. They move 657s complete on these "booster type" trailers. The 16-16-16 mechanical steerables are a little too heavy to legal them. Check out Murray Trailers website or Cozads. Neat stuff. I have not pulled a steerable so my knowledge is from what I have seen & heard.

 

No that trailer is mechanical so there is only a pony motor on the jeep to lift the tower that style trailer doesn't usually leave the ground until the tower is raised and set on hardwood blocks.

Truckdad that's how we count axles as well but we can't get any weight on a sixteen so we don't have them. Closest state to me that will give any weight on a trunnions is Utah but not as much as Cali

 

This is what old scraper haulers do when they're put out to pasture.

 

We can. As a matter of fact we moved a 773 Wednesday on a 9 axle. Gonna depend on the state you are in though.

Another difference you will find, even without a power tower, like our 8 axle, I drop the suspension before backing under. Once I am all hooked up then I put air back in the suspension of the jeep and up it comes. It does look like the trailer was picked up 2-3" in the video. Hard to see but you do see the trailer rocking when he gets back under it.

 

@Hurst. Heres a P.O.S. I winched on then drug it off to a guys scrap yard years ago, 1986 I think. Ca put the end to trailing (bigger units) when they limited wheel weight to 18K lbs. Until then, you still had to have working brakes on the trailing axle. Yeah, like they worked........ We just ran a hose for looks!
