Dual Lifting Arms

Dual Lifting Arms GBC module from nxtstep101 is slightly inspired from Akiyuky’s Lifter Triggered by a Stuck Ball module. The simplicity of building of this marble run machine, its reliability as well as the fact it uses mainly common LEGO parts make it a truly excellent choice to start with LEGO GBC. This Great Ball Contraption consists in two arms that are alternatively lifting balls towards an upper exit ramp. Thanks to a smart mechanism, GBC balls are blocked until they are caught one by one by articulated arms. Reproduce this module thanks to Free Building Instructions available on Planet GBC.
