Working Hammerhead Shipyard Crane - Hand Crank Slew, Trolley, Hoist (1:200)

A hand-cranked WORKING model of a hammerhead (Titan) shipyard crane at 1:200 (about 310 mm tall, jib 415 mm in four segments). Three hand cranks and no ropes: a slewing ring gear turns the head 360 degrees, a rack along the jib top chord moves the trolley, and a rack column raises and lowers the hoist 0-24 m. Each jib segment holds a whole number of rack teeth so the rack runs on across the joints. This is the free single-scale 1:200 set: 15 STL files, no supports (PrusaSlicer-checked, 0.4 mm nozzle, 0.2 mm layers), about 220 g. The hoist column hangs beside the jib plate (side-slung hook). Designed and slice-checked, NOT test-printed yet - renders, not photos. The hull and quay in the pictures are render props and are not included. The full kit with 1:200 + N 1:160 and multicolour 3MF files is on Cults3D: https://cults3d.com/en/3d-model/game/working-hammerhead-shipyard-crane-model-hand-crank-slew-trolley-hoist-1-200 . Part of a series of working hand-cranked port and railway models. Made with AI assistance (parametric design in Blender).
