I am new in flatbeds needs some help

Yes, and yes. So long as your gross is under 80k, and you can keep your drives in the neighbor hood of 32k-33k the rest should be fine. I'm not anxious to put "40,000 lbs" on a spread as I don't want any more weight on them then necessary when making tighter turns but it's good to know that if the expected payload weight is in line and the load is "centered" slightly behind the center of the trailer, you should be able to safely run across any scale without worry.

 

As far as I know, spreads don't have any unique requirement over conventional tandem axle trailers as far as chaining requirements. I believe if snow is serious and drag chains are required you are to chain at least the outside tires on at least one trailer axle in a typical tractor-trailer combination.

 

It's good everwhere if it is a 48. if longer kingpin rules come into play.

 

Your not planning on running canada then are you?

 

Nova Scotia and Manitoba are 2 Provinces I know for sure don't allow a 10'1". Period. Nova Scotia may "see" a 9' and send you on your way. Manitoba will permit you in to deliver to points in Manitoba, but you have to leave empty and no transit-permits.

 

I think all 4 Western Provinces frown on the bigger spreads. You're good to 37,400lbs on a 54" tandem and 39,600lbs on 72". Given those weights they don't have legal provisions for spreads over 6'.
