Flat and step trailers

Well if you strip enough stuff off....... Anyone else notice they don't give load ratings?

 

That's what I was thinking. Sure it's under 7,000# but that also means it has under 7,000# of material holding it up. I'd be scared to put a large coil in the center

 

Yeah what can you center load on it?

 

I do like the idea of those stationary front winches being recesed in the rail.

 

This one Makes my heart go pitter patter.....

 

Can't say for sure without studying the structure, but it MAY be feasible. Looks like what they've done is ditch the conventional main beams, and replaced it with a tub-like structure, and cap the top with the deck.

The concept is similar to aircraft fuselage, where outer skin carries the load without any backbone structure. Or a dry van, for that matter.

When a structure is subjected to primarily in bending stress, as in open deck trailers, the stress is the highest at the top and the bottom surfaces. On conventional skateboards, that would be deck extrusions (and/or wood) and the flanges on the main beams. On this trailer, you got additional load bearing surface at the bottom. Think the difference between an upside-down U-channel, and a rectangular tube of equal width/height. A rectangular tube will handle equal amount of load with thinner wall thickness (where weight savings come from).

That said, I'd rather have somebody else prove it than me. 'til then, I'll stick with a conventional trailer.

And it's probably more aerodynamic by itself like they claim on website, but then, you got no storage room under the trailer, so people will carry dunnage and stuff on the outside negating the gain. It is a typical thinking of engineers with no practical experience. I know it, 'cause I was one of those guys in my previous life LOL.

 

That's what makes me think it's a pretty weak trailer. Everyone else posts their aluminum trailers load ratings except these guys.

Mac's ratings for standard 2 axle flats are:
M52 - 52k in 4'
M60 - 60k in 4' (8,650#)
M72 - 72k in 4'
M80 - 80k in 4' (Strongest on the market)

Reitnouer
Max Lite - 45k in 4'
Maxmiser - 50k in 4'
BigBubba - 60k in 4'
Bigger Bubba 72k in 4'

East
Beast - 50k in 4'
Beast II - 65k in 4'
MMX - 72k in 4'

Fontaine
Revolution - 60k in 4' (as light as 8,348#)

Benson
524 - 52k in 4' (ultra-light option makes it around 7,200#)
724 - 72k in 4'

Lightweight is easy, strong is easy but light and strong..........

I don't even know if Mac offers the M-52 anymore because too many guys were buying them because of the empty weight and hauling coils and breaking them, then blaming Mac.

I had an East Beast for a while, nice trailer until you sat a coil on it then it looked like a banana. The Benson I had would sag with a load of lumber. I took a pic of the new Fontaine Revolution Hybrid (steel frame/alum floor) with a 2 coils less than 50k combined and it was scary. Ride the wave!


when a 79k single doesn't take the arch out of an 80k Mac but 2 at <50k does this to a Fontaine.............Just make sure you buy the correct equipment to do the job. The Fontaine in the pic should stick to general freight like shingles or lumber.

 

I see nothing wrong with that fontaine. Looks happy to me. Nice big smile.

 

That Fontaine looks like the new Wilsons Malone is renting out to. Like an old sway back mule.
