load limits / capacity on flatbed trailers?

Hello all,

I'm wanting to use an older flatbed trailer to use as a bridge for crossing a small creek that goes through our place. The span is 22 ft or so max which means I can prob cut the trailer in half and have a nice wide crossing.

I want to get the heaviest duty frame / deck combo I can afford. Ideally, once I place, I will be able to drive a loaded tandem dump over to the other side to spread gravel/continue building the driveway up (that is approx 45K lbs when loaded). Those of you familiar with flatbed loads, is this a reasonable expectation or crazy town to try something like this?

There's not a lot in the budget for this so I want to be careful in what I'm buying. Any advice? Thanks all

 

All good questions. I'm seeing that the steel trailers with wooden decking are the most affordable. I'm looking around and seeing different options, not sure what configuration would give me the best options as far as the decking.

 

Thought about it but I don't have anything heavy duty enough to bring it here or move it around when it gets here. Also they are $! At least the ones I can see that are reasonably close. Good option though.

That's super helpful. I'm thinking that if I go this route, I can split the trailer in half (length wise), cut off the supports on the two "middle" sections and will be able to set it up so that the two sections of main beams will be (roughly) at the track width of my dump truck so most of the weight will be over the strongest part of the trailer sections.
