Whats the advantage/differnce of split axle trailers vs tandom axle trailers?

do you think it has to do with weight? and state regulations??

there is a discussion on here "somewhere" about it. one of those guys will post actual facts.

I think if I remember correctly, they can put 40,000 pounds on the spread axle.

 

tandems are good for 34k lbs, separate axles are good for 20k each

 

Flying Dutchman is right. Because the axles are 10"2" apart they are considered single axles and you can run 20k on each. When you're hauling 48,000 single coils and such you don't have to be precise on the placement of the coil, the spread axle configuration is very forgiving!!! Plus they ride nice.

 

Also, the spread axle reefers that you see are mostly 48 foot trailers. So they are a little shorter. Goes well with a long wheelbase truck, especially if you have a dump on the back axle. You can back that trailer into any hole without much problem, once you have a little practice.

 

I have always preferred them , but thats me.

 

Might ride better and help with weight but backing into a hole is a bigger pain in the ### and they eat up tires too!

 

What about the California 40-foot kingpin-to-center-of-rear axle rule? How does that work? I asked some driver in Arizona, and all he could tell me was "I don't run in California" (A pretty good idea).

 

I refuse load's going anywhere in Cali, Boston, or NYC (unless passing through on I-95) or Canada. Other than that I'll go anywhere. I'm not sure about the 40' to center rule there concerning spreads. I know they have a lot of spread axle refer's running around there. Note that some spread axle refers are set up to slide where a single axle can be slid independantly or both together as a set.
