Bleichert RK3 Bekohlungskran (HSB) in G-scale / 1:22.5

prusaprinters

This is my interpretation of a typical DDR "Bleichert RK3" crane in G-scale (1:22.5).The HSB in Wernigerode (D), and other museum railways still uses them to load coal on their steam engines.There is hardly any open source information to be found about these "East German" cranes.I have based my model mainly on pictures from my my private collection and found on the internet. If you can provide detailed drawings, I will improve my model.Manual operation of the winches for boom angle and raising the load is achieved by turning two "thumbwheels". They are mounted on a M4 thread, with a spring (i.e. ballpoint pen) in between for friction.Construction:M2, M3 or M4 screw threads are provided for connecting items.Hand rails: 1.75 mm filament or metal wire.Operating levers. 1.75 mm filament.Door hinges: ~1 mm metal wireTo correctly align the pulley on top of the boom, and the ladder to the main body, use some 1.75 mm filament.(Positive) feedback to improve this model is welcome.Best regards,Rob Print SettingsPrinter Brand:CrealityPrinter: CR-10Rafts:NoSupports: YesResolution:.15Infill: 25%Filament: Extrudr GreenTEC / GreenTEC Pro-CARBON Black
