MOC: Six axle self-steering drawbar trailer

[dr_spock]

Greetings.

I've been trying to build a self-steering multi-axle heavy transport modular trailer. After much experimenting, I've finally built a working steering mechanism. I used this real world example as a model.

Here is my Lego version of that picture. My 8294 excavator isn't as big as the Hitachi. Maybe that's excuse to get the new 8043 motorized excavator.

I tested it with an abnormal load. That's all the unused Lego plates I have in the world.

I made a video of it working. The steering is mechnically controlled by the angle of the drawbar in relation to the trailer.

Thanks for watching.

I love it, excellent work.

Such a simple, yet elegant steering! I like the way you used springs, to gain higher steering angle on the arm!

Wow, that thing is awesome

Oooh, nice concept! Well done.
