A little advise on using a 48' flat and a front yoke hauling 120' beams, please.

Good luck. We have a bridge beam builder around here that ships lots of stuff about that size. For anything over 100' total length, they must use a steerable rear tiller, I was told. Man riding and steering in a cab at the back of the load. Also, they had a long one turn over going around a banked curve in the road, were not using the rear unit . They said being that long a load, going into a short curve, the center of gravity gets so far from the centerline that it gets tipsy, but the rear driver, if used, could keep it in line better.
Glad it is you and not me.

 

i've haven't looked that closely but it looks to me like they just sit the things on the trailer. with extra long air lines. stap or chain it down and pull the load with the trailer.

i have no idea on hookup to truck though. lbut the trailer just looks like a regular ole trailer. so your kingpin really wouldn't change, per say.


wouldn't the permits go on something lengthwise for something that long? instead of the typical measurements they might ask for on the shorter long loads????

i know in montana,. they just want permits for anything that takes your overall length past 75 feet.

and i think wyoming is something similar.

 

I helped a friend with a site move one time using the same method. One turn, straighten out, and drive forward to where the beams would be lifted and set for the new bridge. Each beam was 140-feet long.

The turn was a right-hand, shallow turn around a sign (really, I think the sign could have been removed).

Anyway, in short, the turn radius necessary to move something that long is unimaginably large. The only reason we could get away with simply using a bolster and flatbed to do this site move is because it was a closed down interstate. Each truck needed every bit of space to make the turn.

If you're going down the road, I would highly suggest having a steerable. You could look into an older style steerable that uses cable rather than dropping the cash for a new umbilical or radio-controlled (the older one's work similar to a logging bunk).

 

They have a deck that hooks to the 5th wheel, and then you have a dolly under the back. That long ,I have seen steerable Dolly's, that are either manually steered or radio controlled . I can't remember the new name.. But savage in salt lake sold to them. They haul anything.. Try calling Savage as they should be able to Give you the new number. Good luck.

 

I would do a pole trailer. Bolster on front, and back. I don't have enough info to know what you need. I hauled expandable trailers that stretched to 90 feet. Never seen one longer. 110' concrete bridge beams. Did fine. I think using a 48' is going to be a problem for you.
