Trailer loading ramps question

[MAD MARK]

Making a new set of loading ramps since my last set buckled under the weight of my tractor while loading it. JD4310 with 48 BH and 430 Bucket. ~ 5500#

Old ramps were 3" angle 3/16" thick.
New ramps were going to be built to same dimensions just with 1/4" stock.

But, come across some cheap C channel 3" 1/8" thick. I know that C channel is better stiffness wise, especially when comparing the same sizes to angle iron.

So is the C channel of 1/8" thickness stiffer than Angle iron of 1/4" when used in a ramp building application.

I would think the channel iron would be much better than the angle. I have built trailers out if both and I prefer channel.

I have a pair of 6ft aluminum ramps rated for 2500 lbs per axle I use on my car trailer. I have used them to load my 4310 with the bucket full of dirt and my grader blade on. A backhoe might be their undoing though.

Build them out of the 1/4" angle, aesthetics and ease of construction are my reasoning. My 20' trailer ramps are 1/4" thick and rated for 7000lbs according to the manufacturer. I will snap a picture of them tonight. I hate lifting them and putting them back in the slots on the sides, but I doubt I will ever destroy them.

Only asking about the C Channel because I can pick that up for $5 a stick (5' already cut to length).

I took a picture of my ramps in where you can see they were bent, and I bent them back into place causing a "crease" in the sides. They were 2x2x3/16

You could hammer that back flat and just weld on an additional piece of angle iron on both sides on both ramps and it would be stronger.

Thats what I was thinking about doing. I know the integrity of metal doesnt like much to be bending back and forth though. It bent after using it 2 times so I figured I was pushing it way too hard.

Cut and weld some 3/16" or 1/4" x 2" flat to fit between the angle cross members on both sides. That makes it easy to weld the ends to the angle cross members and to the side angle. That will be as strong as channel and take a lot less time to make.

I built ramps using 4 inch channel with 3/16 angle as the rungs. They are plenty strong, but do require assist springs because of the weight.

Those would probably hold a dozer!

Yeah, they look plenty robust
