Bobcat Trailer Blueprints/Plans

I am taking an advanced metal course in High School. I needed a project that I could work on over a course of 9 months. My dad needs a trailer that can haul seed pallets and our Bobcat at the same time. It needs to be a low to the ground trailer, gooseneck, and tilt on the back so we can load the Bobcat. This is what kind of bobcat we are hauling:

It is around 6,500 LBS. I found a trailer that is what I need:

My problem is, I can't find any blueprints or plans that are free or even for sale. I need blueprint or plans for the trailer in order for my instructor to let me build it. I was wondering if anyone out there knew where I could get ahold of plans for a trailer similar to the one I showed above.

Do you need an actual blue print? Or just instructions and a design? I could draw up a basic drawing for you of a design that I did. Here is a pic of it, it can easily be made into a gooseneck. I don't have any blueprints tho, and no way to get them. If someone could do up a computer drawing I would be happy to work with them to make up something.

No, its made to just tilt by balance. The rear part is slightly rear heavy so when you pull the lock lever it just drops down. When you back on it just over centers and drops down and latches. To lock it down when empty you just walk up the tilt part and it tilts down and latches. The latches are spring loaded with a lock to hold them open when unloading and they just latch when loading. To unload you lock the latch open and drive off and it just tips down.

Have you carefully thought out making this trailer a gooseneck? Not too many skid loader trailers are goosenecks for several good reasons. Here are a few things to consider if you haven't already.

Gooseneck trailers are longer than bumper hitch trailers from coupler to axles, this means it takes more space to turn one around. Most skiddy trailers go into a lot of construction areas and there is usually not a lot of space to maneuver and a gooseneck can be a problem.

Another is ride height, a gooseneck needs a lot more frame than the same length bumper trailer and that translates into extra height. For this type design that extra height means even more length to keep the loading angle usable.

That extra frame mentioned above also means extra weight, a lot more. That means more cost and wear on the tow vehicle for every mile driven, including longer stopping and excellerating times.

Finally the extra framing means a lot more $, I would estimate at least double the steel costs for the same bed length.

Most skid loader trailers make realatively short trips compared to say a deckover, mostly less than 50 miles for skid trailers where hundreds of miles for deckovers is common. This means that the towability advantages of a gooseneck are not as great for a skid loader trailer as with a flatbed.

I am going to have to disagree with your statement about the trailer being longer and harder to get around. If you ever pulled a gooseneck you would know they are more maneuverable than a bumper hitch. I have a couple of goosenecks that are 24 and 26 feet long beds and they turn a lot shorter than most car trailers. Besides that they pull easier and ride a lot better than a bumper hitch. With a gooseneck your wheels don't have be any further back than a bumper hitch.

The most compelling reasons to buy rather than build are to buy a manufactured trailer is far cheaper in terms of cost plus valuable time, easier to document, has a warranty (when new) and the manufacturer is the deep pocket that gets sued if there is an injury-causing failure due to design, materials, and/or workmanship. (You too could collect some recovery $$ if there were such a suit).

I have been more than 3 years of "spare time" converting a travel trailer frame into a general purpose flat deck and though I have enjoyed doing it I will never do this again.

The only compelling reason I see for building your own is you have a distinctly unique need and can't buy manufactured trailer to meet that need.

Go ahead and build your trailer. You won't save much if any money but when you are done you should have something you can be proud of and I am sure your dad will be proud of you.

Also you will get lots of practice welding and under the supervision of your instructor I am sure it will turn out strong and safe.

If you can't find blueprints make your own. Photograph, measure and take notes on every similar trailer you see. Then draw it up in SketchUp which is free or whatever CAD system your school has available.

Good luck and post lots of pics here on your progress.

It will be good to draw up your own plans, be goid experience. Post them on here and we may be able to point out helpful changes.

Maybe you should think about a decent digital camera, instead of phone pix. Explain to your instructor that you are on THIS website, and would like to document the build to share with the members on here. Show him the web site and after he has checked it out, may give you permission to do so. Who knows, he may end up joining as a member, too. Others in your class may be interested in finding out about Welding Web as well. So spread the word amongst the class. No harm in trying. I can understand the reason for no phones allowed, too much of a distraction from what you are there for. But a camera ONLY device may be acceptable to the instructor. It's worth asking about, anyway.

No need to reinvent the wheel. I would go and find a trailer that would suit your purpose and measure it. Draw some three view sketches, then dimension them using the example trailer.

Also, are you any good with CAD? A sketchup, solidworks, or rhino type model will help you nail down the design and dimensions, and would probably help you get a better grade in the class.

@ Farmboy-25 - ambitious project. Cool goal. For your consideration, a lowboy goosneck trailer plans, NON-TILT with hideaway ramps.

You could customize your trailer according to your needs. Seems to me your tilt function is a desirement vice a requirement for on/offloading a skidsteer.

I'm trying to get a full line of machinery to go with the 53 dc I have that dad bought new. I also have a 56
400d and I want an early 830 com eh. I have most of the full line of machinery to go with those so when I can quit driving I can farm a small place with just case machinery. Then last year I bought the project 1030 you see in the pics. That kinda threw a wrench in the plan. Lol

i cant help you much with plans, but i remember highschool!

in my class, we had a big dump trailer, an inclosed trailer (20' i believe), and an 8' dirt-bike ramp all come out of there looking quite factory. thats the beauty of being young, your imagination is your limit, and your teacher, if he is anything like the one i had, will help you push the envelope. i never built anything big or cool, never had the customer (money), but boy did i have plans.

do it right, put your time into planning, grind out anything that looks bad, and you'll be just fine
