Landoll 440a max payload

We've got a Landoll 440a sliding axle trailer and recently purchased a Hoist FR 60/80 forklift.

The bare machine without counterweights weighs around 43,000 LB. I think I can scale it on the Landoll, if I park it just right, or at least permit it in the state of TN.

The question I have is will the Landoll load/unload that kind of weight? I know it's a 40 ton trailer and we have hauled over 45k on the deck but the most we've ever loaded/unloaded was a 35,000 LB forklift and it grunts a little with it. The geometry changes a lot on the frame and axles during the tilting process and just don't want to tear something up.

For those that have pulled a Landoll, what's the max weight you've loaded/unloaded?

The reason I'd like to haul it on the Landoll is to try to stay legal. I could haul it fine on our 50 ton RGN but that setup is 44k empty and would definitely be a permit load. I've either got to try and make it work on the Landoll, buy a permit, or find me a 35 ton RGN to get legal.

 

That's sometimes easier said than done, especially if you have a full deck. The problem is, you get the 5th wheel light before you can get the axles ahead enough to let the back of the trailer to hit the ground.
