Here‘s an explanation of the mechanism, for those who are curionus: As the arm reaches the end of the turn, it switches a lever to the side, witch is connected to a shaft, that switches a lego clutch that. changes direction. the shaft is spring loaded, so it doesn‘t just go into neutral, but to the other side. Theres, a differential gear that is connected to the mechanism. it compares two forces in the mechanism: the red arm, and the turntable. When the direction changes, the red lever thing can move freely, and takes less force than the turntable to spin. so it rotates. This gives time for the pneumatic valve on the opposite side of the direction lever to trigger, and pivot the crane utilizing pneumatics. It is perfectly timed that once the pneumatics are finished, the red lever is been stopped by a lego stud, so it can‘t move freely any more. Because of this, the differential decides to drive the turntable instead. once the crane reaches the other side, the whole process is repeated.

Oeli Maurer this is the perfect explanation. thank you very much
awesome! i might have to steal the auto reverse/ directional selector at 1:06
very well done. I like it :)
Great work!
Very cool! I like how it instantly flips down.
