Trailer Ramps, help with fab

I just picked up a trailer and the ramps are not long enough.

I figure I will need an 8' ramp to get the Porsche safely on the trailer without damaging the spoiler etc.

I am looking for suggestions on ramp designs.

I have a gas welding rig and simple fabrication skills. Obviously the goal is strong enough with low weight.

My only experience is with welding steel. I could learn how to weld alum but I would prefer to keep it simple.

Cheers!

Make sure you don't make them so long they hit the axle when you stow them. I made mine six feet for that reason. I used angle, topped with aluminum plate.

Assuming you have built in ramp carrying slots like these, under the center of the trailer why not just use extensions? again like these from Race ramps



or you could make you own from wood, like these


how high and long they need to be depends on the clearance at the front of the car

these are for a 997GT3 and need to be longer than the 3" rise in 3' ones I needed for my 993

Thanks for the replies.

Hey captain Was 16 ga alum sufficient for the deck? Any issues with distortion? I like the idea of welding a ladder frame then riveting on a deck.

The ramps stow across the bed so 8í will work. Itís a big tex wood deck trailer.

I used to borrow my friends trailer so I have already experienced wooden extensions - I was hoping to get away from all that drama.

Keep 'em coming!

These aren't cheap but they work great, maybe you could fab something similar:

Try driving the rear wheels of the tow vehicle onto small ramps. This will lift the front of the trailer, and require less of an angle for the car to negotiate.

A friend fabbed up some 92" long ramps for my 16' car hauler. They slide under the dove tail sideways nicely (he also did some brackets).

They work very well on my lowered Turbo Look (deep front spoiler), although I still need to jack up the front of the trailer about 4".

A word of caution though, my ramps are steel and quite heavy. Aluminum would be much better.

Also, sideways mounted means you need to have room on the side to slide them in and out. If someone parks next to you and leaves, you need to move the trailer to get the ramps back in. Not amusing after a long hot day at an event.

There is a picture somewhere (here or maybe Corner-Carvers.com) of a set of fabbed up folding ramps that attach to the end of the trailer with piano-type hinges. Pretty nifty.

Yes, it's fine. No distortion. I did go with 3/16" steel though. The ramps survived the inaugural test just fine: Driving my old Dodge Durango up them (only raised 6" at one end).

If the original ramps on your trailer looked like mine, they are only fit for loading a tractor.

Here's the obligatory pic...

I had an 18' "Big Tex" trailer that had the integral slots to stow the ramps. I needed 11' ramps to get my car up without having to resort to secondary extensions. I've always hated secondary extensions as they are one more thing to have to set-up, take with, or cause a problem.

I hate using helper ramps but the max angle the car can tolerate is 8 deg. However on a 4" helper ramp the car can clear 10 deg. Doesn't sound like much but makes a big diff.

So I think I am resigned to helper ramps I will just make them extra wide and stable. Also they will have an interlocking feature so they won't kick out.

X2 on aluminum, I might just learn how to weld the stuff.

I have the nagging thought that it will be cheaper to just buy instead of making my own. But I won't learn anything and I think I can do better!

The big tex ramps are super strong but only 48" long, duh! CraigsList!!

Anyone know where I can get serrated alum strip? Approx 3 x 1/4 plus serrations.
