Big Load

I saw this load parked near here (SW Kansas) over the weekend. Not sure what it was, but it was obviously heavy!!!

I didn't climb around on it to see if the engine in back was a pusher or just for the hydraulics...

Hard to guess what's under the wrap, but my first guess is that's an amusement park ride that hasn't been unfolded and set up. That would explain the engine on the back. No two ways about it, that's quite a trailer!
 
Looking at the shape of the load I would say it is a large bed for a large mining dump truck. The bed is turned upside down over the frame assembly. I would hate to have to buy a set of tires for that outfit. DH
 

We see a lot of really odd transports through this area... The traffic is light out here compared to other areas and there are several main highways that intersect...

We sometimes see mining gear headed through this area towards the north...

I'm pretty sure the rear engine was part of the truck rigging for hauling... Occasionally, there will be a pusher tractor on the rear, too.

I saw one a while back similar to this, but the tractor on back had a huge trailer ball near where the hood ornament would go that the rear of the trailer mounted to...

My guess is that the rear engine is for the trailer as this trailer has rear stearing. Notice the platform to stand on with controls in the back. . You would never see anything that big near me. Really cool pics though.
 
Very little ground clearance- what happens if it crosses a raised railroad track? I'm guessing the bed can be raised somewhat?
 
The third axle from the back looks to be a drive axle. The center one in the group of three in the last picture.
 
A lot of these large loads are on their way to the Piceance basin in western colorado from Houston, texas , they go north as far a cheyenne wyoming, then west to crested Junction a then south on US 789 They avoid the high mountian passen and some tunnels.
 
WOW thats some big rig .... Do you think that someone rides on the back in the cage and drives the back end ?? see theres controls and a cyl. that looks like it is the steering for the back...
Anyway.... GREAT Pictures ... THANKS for shareing ...

WOW!!

My guess about the rear unit is that it is a pusher and hydraulic unit as well. The twin diesel stacks suggest about 600 Hp, and there is a visible hydraulic cooler. I would suspect the rear power is particularly important for manuvering the rear end in tight quarters at low speed, kind of like when it needs to steer sideways to get around some corner. I suspect the load is lifted by large hydraulic cylinders to get sufficient road clearance. I wonder about going over bridges (I'm from MN and we had the huge I 35 W bridge go down in the Mississippi river 2 Augusts ago...with considerable loss of life!). Today's house moving dollys have vertical hydraulic cylinders to raise the house high enough to clear the railings on bridges that are too narrow for the house. But house moving is a very small % of the weight being hauled here. This has got to be one expensive haul!!

What an interesting post and sight.

Unless I miscounted that is a 70 wheeler. Sure makes 18 wheelers look like wimps in comparison.

Sure would be fun to know what the load is.

I don't think wind turbine components are that large are they? That would have been my first thought.
 
the third axle frm the back may be powered as it has a live axle end, instead of just a bearing cap, probably powered by hydraulics, the rear unit is mainly hydraulic power for the whole trailer assembly from the tractor back, the pto on the tractor could not supply near enough volume to run this all the sections are steerable as well as can lift up and lower as needed, thats not a mining truck bed those come thru here regularly and are hauled right side up and exposed on a rig about half that size escorts front and rear as those beds are 24 feet wide, after watching them
wiggle" as they go down the road no way do i want to haul one! this has to be a electic power turbine like goes in a dam to generate power or something like that to be so heavy
 
Correct about the hyd drive and steer. The lifting is done with air. That power unit most likely has a hyd pump for steer cylinders and a drive pump as well as a big air compressor.

I found their website and it is really interesting!

Looks like they can haul over 400,000 pounds with their largest capacity trailers... They list twin 550hp Cats as drive units on the largest trailer. I assume that is the tractor and this rear unit...

I agree that it probably is a generator or reactor or something to be SO heavy...

We have big wind turbine generators & blades come through here all the time - and also the huge mining truck beds (usually 1/2 at a time) - and they are big - but nothing like this! This thing was almost a city block long...

Diamond Heavy Haul
 
Hello folks. As a truck driver myself, I see these kinds of payloads often on the highways. they weigh around 100,000-500,000 pounds. I haul no where near that. I am only registered to weigh 80,000 pounds gross. In order to haul this kind of payload requires experience, patience, permits, and a lot of time. The truck usually does all the pulling. The engine at the rear powers the hydraulics which allows the operator with the controls to turn the payload around tight corners. The engine also supplies air for the brakes and suspension. I have seen these trucks in action and are amazing to watch. It is currently sitting on the ground to take the weight off the equipment when parked, performing repairs, etc. They are only allowed to drive during daylight hours. Each state they must travel through requires police escort and can only go on specific routes dictated by each state. While in motion, the bed is only between 6-12 inches off the ground
