Pins in the gripper arms fit into holes in each section of pipe

So, thinking as the desk-mechanical engineer, tasked with designing each lifting-section of the wind turbine tower itself; consider the tower, then the weight and moment arm of this new crane-thing we’re going to hang on the side, then the weight of everything we’ll need to lift with it. Oh, and don’t forget to factor in maximal wind effects for each phase and each lift!

Lemme know if you have any questions!
