I actualy got this idea from the amazing game "Lego Indiana Jones" It`s from that level in the Raiders of the Lost Ark that you start out next to a brocken crane and you have to fix it. Note that I DID NOT take this exactly from the game, I only took the idea to make a crane!
About this creation
In my opinion this is the coolest picture I have done with legos.
The only reason I did this was because I don`t have any roll cage pieces (surprisingly because all the tens of thousands of legos I have, not kiding.)
And what`s a crane if it can`t move the boom up and down? Thanks to this turny piece, a couple of gears, and a few tecnic pieces that came true.
This is not as far as it can go (it can go strait up) but it was just to show you that it can go up.
