Big Loads - Post Photos Number 2

Yes it does.
What you're referring to are SPMT's, Self Propelled Modular Trailers. Or as I refer to them, the most awesome r/c cars man ever made!
This is drawbar controlled, not SPMT. It has hydraulic suspension and you can "break" mechanical steering and hydraulically steer it, but it does not have hydraulic wheel motors, and uses air brakes.

In this screenshot (approx :47) you can see the mechanical linkage.

 

Maybe so, I’m not sure the tongue is controlling the steering or if it’s slave steered. It has a hydraulic suspension I’m not sure about the brakes. They may be air.

 

I did not get a chance to test load it. They were so far behind and I have to be in MO by tuesday - so waiting until Monday wasn’t an option. I did measure it and weigh it empty by axle group.

I will be looking to load it out of possibly one of the KEEN yards in IL on the 20th or 21st. That way I can test weigh it on their axle scale and adjust the proportioning valve on the lift axle if necessary. I will have a little room to adjust weight but will still end up light on my steer when open to the 13’6.

 

Looks cool! Hope it works out for you.

 

Looks good Ron.

 

Yeah all of the platforms I've worked around have also been self driven with a power pack hanging off the front.

Here's a Diagram from a PDF on the Goldhifer website showing how they are setup for mechanical steering. All the ones I've ever seen with mechanical steering are usually designed with highway travel in mind.

As a guy with 0 experience with large platforms other than I stood 20ft from one on a job site I think they had the wrong equipment for the job. A SPMT like you were talking of wouldn't have pushed the truck out of the way and then chased it off a cliff. They would've had control of each axles drive to control speed and steering in a straight line.

I also wonder if more ballast on the tractors would've helped with traction. Doesn't look like either of them have a whole lot on the back compared to the size of some ballast boxes I've seen.

 

Now you have to polish all the other wheels.....just sayin.

 

so much easier to just get the shiny ones dirty....

I am not a polisher, it is a defect I am sure

 

Polishing sucks. I hate it too lol.

 

No load pics??
