Lift axle size and spacing help....

Ship lap cut apitong decking is a absolute must for me.

 

You have me curious now lol the scalemaster was in ohio? Did he give you an exact number on the weight allowed on the tridem? The way l understood it was that that tridem in Mi would be good for 39000. 13 per axle. If you move the lift forward until you have 9' between the front drive and the lift you are good for 18 on that axle if you have enough tire for it. You need at least 9' to the steer axle to get 18/20 on the front axle too. On Ohio trucks they usually would have another lift just like you already have tight to it. Then they would be worth 13 apiece when you are in Mi. Tune me in if l'm completely wrong lol

 

where i run i have a 12k steerable on my truck and get 42500 on my drive axle group on bridge law loads, i forget the exact spacing 9'2 or 9'6 something like that. they allow the weight to be split 34k on the drive tandems and the pusher has to carry at least 8500 to be legal, i normally keep my pusher set at 9500

 

Yep that sounds about right...that thing is gonna be mad heavy empty.. and hard on the truck on loads that heavy!

 

How much is that extra lift gonna add to tare weight? Places to the rear of the drives/ do you have that much frame? And are you good for 62.5k on state routes currently?

 

We need flatbeds like this! LOLOL. How friggin useless!!

 

I've seen farm pick up milk tanker straight trucks in mi set up with 4 axles at the back. Rear and front axles are lifts. Probably for the same reason you're thinking of doing it.

 

I see a lot of super duty flatbed straight trucks set up like that in Michigan too....from what I see they are hauling injection molds....crazy heavy for what they are! The Ford F-150 dashboard mold weighs 26,500 lbs and that was a small one! I see many that are 45k but small so they go nice on built up straight flats.
