Question about Grain doubles / pup set-up

Talk to your local trailer dealer for Wilson, Cornhusker or Timpte. Or go their web sites, They will build anything you want, but it will be expensive. You can't just add a pintle hook to an aluminmun trailer, they may not be strong enough to handle the extra pulling weight. Your laws in Michigan allow heavier weights than most other states, and the trailers must be structurally engineered for the extra weight.

 

Sounds like a Super-B train, but with a pintle hook instead of a second fifth wheel.

You looking for something like this?

 

You can pull the second trailer with a pintle hitch, you do not need to have it on the 5th wheel. Or you get the pup trailer with con gear under the front so you can pull it out and slide the truck under the trailer.

 

AFAIK each trailer in a michigan train are limited to 28 1/2 feet long. You could try and run a tandem converter and a tandem 24 foot pup. It would cut your drives back to 32,000 lbs and 26,000 on the pups tandem. On the lead you would be good for 39,000 on the tridem and the converter would be good for another 26,000. One other option is to run a lift axle on the truck itself to boost the drive weight to 39,000. It should also allow you to run the convertor or the tandem at 32,000 lbs as long as the other is 26,000lbs. Whew! Not too confusing is it lol After all this you would still be illegal because of the lead being overlength. You might get away with it as long as your not crossing scales though. Good luck with your choice. Hopefully this info is still somewhat accurate.
