Harland and Wolff - Shipbuilding and Engineering Works

Following a request to create an electrical demonstration for visiting schoolchildren, the idea of building a fully working 1:100 scale model of the Goliath crane came to mind — and that is where the project began.
The original plan was to construct the model from wood. However, after assembling several early prototypes, it became clear that 3D printing would allow for far greater detail and precision. This new direction opened up exciting possibilities, but it also presented a significant challenge, as I had no prior experience in 3D design or printing.
After extensive research and a number of trial demonstrations, I selected Onshape as the modelling platform and Cura for slicing the print files. Using original Krupp drawings as reference material, each component was carefully modelled, sliced, and printed. Additional parts were specifically designed for the mechanical systems, including motor mounts, gearing, and other moving elements.
From an electrical perspective, I wanted the controls to replicate the crane’s original control panel as closely as possible, giving users a realistic, hands-on experience. The wiring layout was designed with authenticity in mind, and a dedicated control panel was constructed, tested, and refined.
After many long hours of 3D modelling, printing, construction, and wiring — along with more than a few setbacks and frustrations — the model finally came to life, successfully lifting and moving a ship’s block.
The completed model was successfully transferred from Ballygown to Harland and Wolff on 10-02-2026, where it will remain for future generations of shipyard workers and visitors to enjoy.
