what is the maximum length for truck transporting in Louisiana?

[delagina]

I have shop assembled platform that is 12' width and 40' length.
can this be transported by a truck?
What is the maximum length you splice a column or beam? I normally use 36' maximum.

Is there any link/table for truck length maximum length capacity?

I can't answer for Louisiana, but I don't worry about splicing columns until they get close to 50'. Most semi trailers are 52' or 53' and I think you are allowed 5' or 10' overhang so you could possibly go farther but I've typically had trouble with beam availability at that point.

You'll need an escort for your platform I'd imagine, but it's transportable.

any guide how the cost of transporting steel platform as shop assembled become more expensive than building it on site?

 

[robyengIT]

these investigations should not be done before design and construction ?

Delagina:
Given your questions and OP’s. you/your company must work on an incredible variety of projects and engineering problems. They just stagger my imagination. 40' length should be no problem almost anyplace, but the 12' width will cause some problems. This width can often be accommodated by placing the load on its side on the trailer, on some approx. 45̊ angled frames which allow you to minimize the total width, while at the same time to increase the height; some adjustments to take advantage of each allowable max. dimension. Unless the site work is very typical site fabrication, assembly and erection it is usually best to do this work in a fab. shop and ship the entire piece, with the transport considerations stretched to their limits. Pick up your phone and ask the local authorities, police, highway depts., local truckers, etc., they can give you the straight local answers.

Do they use mobile homes in Louisiana? Yes. So, 12' wide by 40' long is no problem. It'll be a "permit load", may or may not require an escort, may be limited on some of the bridges (the old Huey Long bridge was pretty narrow as I recall.) 40' length is never a problem, normal flatbeds are that long, many are longer. Up to maybe 15' wide, not too much of a problem. Up to 14' high, not too much of a problem. Over that, you start running into clearance issues with overpasses and all.

Just checking, I see that wind turbine blades 100-120' long are routinely hauled around the country. Precast concrete bridge beams are routinely hauled around that are considerably longer than 40'. They're all permit loads, but doable.

We ship long pieces all over. Up to 53' long is generally considered 'legal' everywhere and will ship without additional permits or cost on a standard trailer. You can ship longer, but it becomes difficult to deal with each state and their laws & permitting. Our loads typically stay at legal widths so I'm not familiar with the rules for that.

In state, we'll ship 85' column pipes (usually 42" dia) on an extendable trailer. Not crossing state lines makes it easy.
