Estimating axle weights for annual overweight permit?

We need to pull an annual overweight permit for the first time. This is Florida. The permit application requires us to document axle spacing and weights. These will be 20' tri-axle chassis, but I don't see how we can accurately predict the weights in advance of even hooking to the load...

Anybody have experience/tips about how to deal with this?

Thanks!

 

Gross weight, using max weight on all axles would far exceed the 100K limit for overweight containers. The permit office advised us to just specify max legal dimensions but when it came to weights she said she had no idea. Er, thanks!

We also must specify axle spacing ... on a rental. Having fun yet?

That's another part of the problem, it will vary (including down into legal weight territory), but we've been told to expect as much as 60,000 in some cases. (If I remember right, 20 footers have a 65,000 limit -- the container itself, I mean.)

 

Yeah the axle count will not change but I'll have to take a look at the spacing issue.

Thanks everyone.

 

Today three different people at the permitting office told me the axle weights on a blanket permit don't matter -- they use the same form for all permit applications so it's required but ignored. I probably wouldn't buy that from one or two people but I start feeling a little safer the third time around...

Axle count and spacing does still matter, as superhauler noted above.
