Hi there. For several day´s I was working on Nico71´s crawler crane which he made several years ago. Nico allowed me to show you that.
I´ve made it in LDD only from his pictures. He never made instructions for it, only took several pictures of disassembled crane body. So I started step by step. And I´m proud to show you result.
There is 4 motors in superstructure. XL for hook winch, M motor for rotating superstructure, another XL motor for main boom and M motor for luffing jib.
Nico´s original crawler wasn´t motorized. So I´ve decided to add aditional L motors and AAA BBox with IR receiver. There was enough space for it.
Last picture - entire crane disassembled to blocks.
