In Australia and New Zealand they have al kinds of trailers. Real special are the widening trailers. After finding some real nice pdf drawings I decided to develope one of these trailers. It is a quad axle trailer with 4x8 wheels. This meant I had to figure out how to get these wheels. In the future I want to make a 2 axle widening dolly as well so I needed 48 wheels without any spare ones. The solution: I had them 3D printed.
During the time it took to develop the thing I discovered a model in scale 1:50 of a Drake-trailer. Mine is from TRT.
This is the model of the Drake trailer.
And now some pics of the developed trailer and the tire spread out.
And some details
And the developed wheels, rims and tires are separate parts.
All the parts are CNC milled and I'm working on the assembly of them.
