I need some info for my trailer. I have an 18� flat bed trailer to haul tractors with. This trailer does not have a dovetail. Now I have 7� slide out ramps that are a pain to say the least. I want to make and install fold up ramps, but am not sure how long to make them. Is there a set angle that I could go by? My trailer bed is about 30� off the ground. If I could get an angle to go by I can figure the length of the ramp to build. Thanks for any and all input.

Two questions.

Is the trailer able to accept a dovetail?

Would you install a dovetail if you could?

Depending on where your axles are positioned can answer the question of how much dovetail you can have. ASSUMING (you know what that means) you have tandem trailer the center of the axles should be at or around 70% of the length of the trailer. Example; 20' of overall length - not deck length, total length (coupler to tail end), the center equalizer hanger should be at or approx. 14' from front of trailer coupler. Front and rear hangers spaced as required by spring style. Say you have a overall length of 20' and a coupler to center hanger dimension of 16'(on your exisisting trailer), you could if you wanted install 2.5' of dovetail to give you the 70 - 30 % specification. Dovetail's on trailers I sell, have anywhere from a 6 to 11 degree load angle. 6 degree is more for paving equipment and 11 is more for backhoes, crawler loaders, dozers, etc.

2.5' of dovetail is not a great amount but WILL cut your load angle down. With that increase you could go to 6' ramps and flip them up on a piece a pipe or sold rod and attach the ramps accordingly. You will still have more than an 11 degree load angle dimension for your ramps but will be much less than the load angle you are working with at the moment.

OR the less feasible thing to do is buy a new trailer.

Any questions just e-mail. I have a digital camera and can send pictures of the trailers we sell if you tell me the GVWR you require. Most of our trailers are Deckover 16' plus 4' dovetail and 6' Ramps - from 10000 GVWR to 14000 GVWR in stock. Available in gooseneck or drawbar pull and of course different lengths.

Budd, I use a 3 to 1 ratio for equipment loading. That's 3' out for every 1' high. That puts your 7' ramps in the ball park. You could probably get by with 6' ramps but really risk a flip over if the tractor isn't backed on to load it.

~That is a long ramp to fold up in one piece. You might want to look at bi- folding ramps, or building a short beaver tail on the back to lower the attachment point & shorten the ramp length.

~On a 30" high trailer with a 3/1 ramp ratio you will still have problems with low center, or long cars & will have to raise the trailer front or put the trailer wheels in a ditch to load a car.

~Rear pull out ramps would work, but to handle 10,000 lb+ tractors they will have to be heavy & will still be a pain to pull out.

~I used to have a tag trailer with a 26" high deck & just slid the ramps up on the deck between the rear tractor tires as those ramps weighed about 125 lbs each..... ..

Budd, Ive had all shapes and sizes and for hauling those relatively high clearance tractors, about any reasonable length will work (longer is still better and safer provided built strong and cant unattach) HOWEVER, if you try to load most automobiles and dont have longgggg gggg ramps or a lowwwww wwwww trailer, they bottom out at the rear trailers edge BIG TIME. If your bed is 30" above grade and no dovetail, 5 ft or so ramps will probably do fine loading tractors or maybe higher clearance pickups, but not low slung cars. You may as well do a center one also if youre gonna be hauling tricycle tractors. I usually stiff leg mine in the fold up position (about 4 ft ramps but my beds much lower than yours) a little less than vertical, but if you dont like ramps sticking up in the air when hauling, youre gonna have to go the slide out lower shelf type set up. Good luck, Ol John T
