In portal crane project the hook has to be as heavy as possible, otherwise the threads will not be tightened enough and will skip all the time (and will l...
Motor board for portal crane
For some time I’ve wanted to develop a PCB again. Last time I did that was around 2021, when I made LocoNet-equipped decoder and command station for...
Winch based on N20 gearmotor
Any functional crane model obviously requires a winch (or two).
Slip ring ideas, two of them
The functional crane model I’m working on requires a slip ring to rotate superstructure. Currently this is implemented as a 3D-printed casing for bron...
