It has never been easier to build a complete Great Ball Contraption (GBC) loop yourself! This GBC is entirely built using only parts from the LEGO Technic Crawler Crane 42042 set and uses 95% of all the pieces that come with it. It can also to be referred to as the model C of the 42042 Crawler Crane. This module makes sure you master the GBC building techniques and tricks so that you eventually also can build your own GBC. The whole machine is powered by one LEGO motor which comes with the LEGO 42042 Set.

 

 

 

Mechanical automation to its max

 

 

The loop of the GBC 10 Funfair contains 5 Modules and features in the center the big Ferris Wheel Module. But before we come to that let’s start at the beginning.
The GBC Balls starts at the Horizontal Mover Module which takes one ball at a time and then automatically turns them over 180 degrees to drop them into the next module. To make this work we designed a really effective return/pause mechanism which automatically changes the direction of the Horizontal Mover arm. The next module is the Conveyor Belt Module which brings the balls up to the Flip Flop Module. This module separates the balls equally over 2 bins. When a bin is filled up to 8 balls it will automatically empty itself and release the balls back into the loop.

The GBC Balls then go into the big Ferris Wheel Module which is fully mechanical automated. The ferris wheel has 4 cabins each holding 1 ball. The timings mechanisms, which releases one ball in one cabin, uses a specific gear ratios to get the timing right every time. The timing of entering balls into the cabins comes quite precise but when you have the timing just correctly everything works like a charm. After 3/4 of a revolution on the wheel the balls drop of and continue the loop by starting at the begin point again.
Batteries can easily be replaced. If you are out of batteries you can also power the whole GBC manually by turning the yellow handle.
