Flip Neck Box Mechanical RGN Question:

Already planning a fleet are ya?

the foot print of that dozer is much smaller than it’s over all length.

stretch trailer are not designed for heavy concentrated loads - the beam inside beam design cannot handle the weight like a straight through beam. Yes, guys do it and then complain when the trailer sags and has negative arch when stretched and loaded.


If you were going to haul yellow iron you should have bought a trailer designed for that - it would be 6k plus pounds lighter and setup for concentrated loads like dozers.

stretch trailer are really designed and rated for “2 point loads” usually a designated as x feet from the front and back of the well. Yours is likely 45 tons as a 2 point load 2’ from either end. The load itself helps carry the weight. A modular deck would allow for adding deck shim to help
Build the arch or pre-camber of the trailer to support the belly of the trailer and keep it from dragging. You do not have a modular trailer and therefore only have the arch the the trailer de k was originally built with. If you de-arch the trailer by hauling concentrated loads - you will drag with even moderately heavy non-self supporting loads.

The really bad part is your trailer is mechanical and you cannot raise the neck to get over clearance issues like driveways or railroad tracks.
If you go negative in the center of the trailer you have no way to get around other than to try and drag the trailer over the clearance issues. Sometimes you can and sometimes you can’t.

This is basic level stuff and gets more complicated when you start hauling long loads that are easily damaged by not having enough arch or too much arch in the deck. Causing the load to either try to compress or expand in the center…

there is a lot of thinking that goes into this area for trucking. Talking to experienced guys can help
Bridge the gap in knowledge.
This goes back to what I suggested to You earlier - you could have stayed as a 6 axle and learned with loads that would be easier and more forgiving. You would have had the opportunity to learn the questions to ask and seen other guys doing the job. You have jumped into the very deep end of the pool and every mistake could be crippling- either financially or physically.

There many guys on this very site that have huge experience and skill (not me) that you would be smart to listen to very closely.

Except of @truckdad - he will just want you to haul scrapers. I kid…

 

maybe we should sign on!

 

Smart. Get in early

 

@Rontonio just sent you the helicopter, when you were on the roof with the flood waters rising . . .
