Extendo Lift Arm
This is a simple Lego ladder arm build made from Technic. In the real world this is commonly used in cherry pickers. It's very easy to build and not very part expensive but if you find you don't have the right Lego pieces right now, don't fret! Here is a link to all the parts you need! Short arms (x5) Friction less pins (x40) Long arms (x5) You will need 3 pins per 2 short arms. And when you have the necessary parts, you may want to build the ladder arm! If so here is a tutorial made by Charlie himself! Good luck! /\Build this as long as you like/\ Well done! You made it! Now go have fun and maybe modify the design with longer beams or a grabber at the end?
