Next one was a bit larger, total height appr. 0,5 m, but, still having only 1 motor, only luffing is powered.
This model is supposed to look like an existing shipyard crane, working on a ship repair yard in Vlissingen, The Netherlands, the same yard I’m working on.
I tried some solutions for connecting the beams used for the legs under different angles. These worked well for this relatively small and light model.
The idea of building this crane on a larger scale developed into a solid plan. See Figee level luffing crane.
As the real crane is painted mainly blue, I decided to use the same colour in Lego. The decision to use blue, was not very clever cost-wise ( blue material is quite rare and this is reflected by prices).
