Catfish trailer

this is just a quick concept drawing of my entry into the competition a i just dont have time being back in college basically how it works is the two cranks are turned so the swing arm suspension rises this forces the ride height to be lowered to the ground so the catfish can be driven straight on while still connected to the tow vehicle once the car is on the cranks turned the opposite direction and removed. this idea also serves a dual purpose in that the trailer can be risen so the underside of the car can be worked on. for the fold up part of the trailer there is a bolt on brace at the rear and it is also bolted to the hitch bar and the two rail sections are hinged so as to allow the trailer to be stored in a smaller space and can possibly be sold as a flat packed trailer the design would probably need to be strengthend in some ways but i believe the idea is pretty solid
