Default How to build trailer ramps

My name is Sean and I just became a new member here and I have a couple of questions if that is O.K.

I have been welding and fabricating for a couple of years as a hobby. I have a 20 ft car trailer and I need some ramps for it. I have made ramps in the past but they either bend or they are so heavy that they become unwieldy to use.

What suggestions are there? I can weld aluminum but i need some help with design.

Would tubing be a better option? Maybe a small truss under the ramp to prevent bending?

I am towing a 2006 Pathfinder and other assorted cars (projects) so I need each ramp to hold about 3000 lbs.

I am also considering making 1 ramp the full width of the trailer but I am worried that it will be too heavy to swing up easily.

Thanks for the great forum and I look forward to contributing when I can.

Welcome aboard, Sean and thank you for posting that location so we don't have to rag you about it.
I will leave the advice to someone who has built some ramps.

Glad to have you on board Sean. I''ll defer to the more experienced here. Never made any ramps. Guess you could take a look at some commercial ramps and copy what you like.

I have seen car haulers that had hinged ramps that were supported at the hinge area. Everything folded up and looked fairly light weight.

Making them light and strong is always a compromise.

For car ramps, I suggest some 1/4" plate, if you have a fab shop or access to a press brake.

something like this will work....

You can tack weld some expanded metal on the tops for traction.

They will handle a car or truck. heavier equipment like a bobcat or fork lift they will not handle.

car ramps can be fun, they have to be light enough to carry and throw around. i bought a cheap a*s car trailer and the ramps were cheap, they moved around and tipped up when loading. gave me the willes when loading.

take your time and check things out. would not want to be loading and have the ramp move, LOL

So true Shade. I gave up on the "making them light" a long time ago. For typical cars and trucks Shade's drawing will work great, it's the "how long do they need to be?" that will determine the weight and ease of use or storeage.

Making them out of Aluminum will also have them tend to disappear if not permanently affixed to the trailer.

Uh King, we've seen the pictures of you loading a vehicle once before. lol Everything you do on a daily basis scares the hell out of me. Too much iron with engines and much too cold.

Can't offer much on the actual construction, but here are some pics of the ramp on my Father-in-law's hauler.

The ones I have made have always been made from angle iron frame with angle cleats. 1/4x2x2 seems to work ok. I have put full size trucks on them

here are some generic pics of the style I used

If you want to make a full ramp thats permantly attached but its too heavy you can look into these ramp assists

Mine work great--now. The following thread shows a few pics of them, but details more a modification I made to the ones that came with my trailer. I have plans later in the week to show another modification to my ramp system, but it'll be in the same thread.

Thread Here.



They are approximately 41" inches long, 15" wide, and about 50lbs. They are made from 3/16"x2x2 angle, and then decked over with 14ga. sheet. Their original structure was similar to the "generic" ones Cavalry posted in the above post. My problem with them was that smaller car tires would trap themselves between the rungs, making it a major PITA when dragging up an unpowered car by winch.

My trailer does have a pretty good drop, but I think they'd be alright for a standard dove tail trailer. You'd want to lengthen them for sure if you didn't have any drop on your deck.
