Tower Crane Top

The tower crane's turning top: a slew ring and turntable that seats on the mast section's flat 2 m square top flange, a 32 m lattice jib in 4 m panels with pendant ties, a 10 m counter-jib with stacked counterweight blocks and a machinery deck.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
