Me and my son asked ourselves how strong a lego powerfunctions motor is and much weight it would lift.
So I had the idea to build a simple wooden crane out of scraps, construct a simple worm gear box and put this and some other lego parts together for our weight lifting experiment.
Don’t ask me for gear ratios, it’s only a small fun project and we didnt’t do any maths on it.
But feel free to calculate it and send me your result.
Then I will add it to the description and mention your name.
