Small span wide flange beam load sizing

[Blacksheep10]

Spanning a small creek, 24’ truck bed as the deck, so its steel deck, 3” crossmembers, 6” channel rails. Sitting that on wide flange beams the width of the skid steer tracks (so beams will be outside the 6” channel). Figure the bed will hold itself, how big a pair of beams on a 30’ span do I need to hold up a 10,500 lb skid steer. Actual span more like 25’, but doing better safe than sorry. Wild ass guess from me, w12x 16?

I dont know shit
but I come up with the beams would deflect 1-5/8" with a 10K load in the center

That seems like a reasonable amount, I mainly don’t want to end up with a skid steer down in the bottom of a creek

 

[Muckin_Slusher]

No idea, but the beams would be a fuck of a lot smaller if it got a middle support, like sitting on a couple precast blocks tossed in the crick.

Shot in the dark here, why not set a set of box truck frame rails down? The truck bed would bolt on perfectly.

I have about 1000 foot of W30 x116, I was hoping they would do it🤷‍♂️

The guy doesn’t give a fuck it’s gonna be like $1000 in Steel. Ditch is pretty deep in the water really ripped so it’s not getting anything down in the ditch that could wash away. It will be a clear span

 

[Blacksheep10]

Also on the truck frame rails, I have 27 foot of truck frame rail that I could clean the axles out from under but it is truck frame rail with and I would rather have the support memes farther out to the edge where the track width of a pick up or piece of machinery is

Can easily truss the bottom of the beam and gain a ton of strength. I'd probably bump it up a bit like a w12x26.

Anyone understand how that beam calculator works ?

Have a 2nd floor between 2 cans have been wanting to figure out and havent in 2 years since I bought the cans at 6500 each!

Cant seem to find an engineering firm to pay to figure it out.

Never was good at math.

Skid steer top speed? I'm thinking the small deflection won't matter as much if you're doing a ramp instead of a bridge.

Honestly. If it was a double framed truck or class a truck, I'd run it. The flat bed on top has it's own side supports built onto it. Hell, just get a 30' flatbed and take the wheels off it. I'm too cheap to buy non-auction'd beams.

Just use 2 sets of those. Should hold up.

beamboy.exe is the answer...
I'm a broken record

25' W12X16 5000 lb point load at 12' 6"

 

[CarterKraft]

Same beam but 7500lbs evenly distributed

 

[Blacksheep10]

I’ll likely go w14x22 and gain strength while losing 4lb/ft yes?

 

[CarterKraft]

Taller the beam the stronger it is.
Always increase section height as tall as possible before adding material.

 

[bdkw1]

This, if you have 1000' of free material, just throw some more at it.

W14x22 5k lb load centered

 

[CarterKraft]

W14x22 5k lb load centered

Same beam but 10k lb load

 

[CarterKraft]

W16x26 beam 10k load

 

[CarterKraft]

w14x22 13k load centered

Or skin the outsides and increase it astronomically. I've designed some 2 flange I-beams in the past. They were insane.

What happened to the good ol days of building something and hoping the skid steer doesn't fall in the creek?

Not a skid steer. But I immediately thought of this picture!

He doesnt want to end up in the fail thread.
