The crab traverses and the hook hoists. Overall 27.20 by 17.00 by 7.15 m (X by Y by Z). Metre units, +Y up, the working face toward +Z, resting on y=0. The origin is the centre of the span at rail level; it rests on y=0 so the bogies stand on an apron either side of a 16 m dock. The wire rope is modelled as a short fall that travels with the hook block: rope cannot pay out under a rigid node transform, and the festoon cable, the rail clamps and the ladders are solid for the same reason. Rigid node-transform clips: trolley-open, trolley-close, hoist-open and hoist-close. No skinning. No collision or navigation data. Original CC0 geometry: no shipyard, shipping line, shipbuilder, class society or equipment maker is named or depicted, no real vessel is reproduced, and every sign, plate and board face is left blank.","status":"published","url":"https://3dassets.dev/assets/shipyard-and-dry-dock-shipyard-and-dry-dock-dock-gantr-1e428ef8","cdnUrl":"https://cdn.3dassets.dev/assets/37932/v1/model.glb","downloadUrl":"https://3dassets.dev/download/shipyard-and-dry-dock-shipyard-and-dry-dock-dock-gantr-1e428ef8","thumbnailUrl":"https://cdn.3dassets.dev/assets/37932/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/37932/v1/poster.webp","blurhash":"UCBWi3-:M_xt_N?bITIU9FtRaeIT9Fxu-;IU","category":{"slug":"vehicles","title":"Vehicles"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"exterior","title":"Exterior"},{"slug":"kit","title":"Kit / Set"},{"slug":"animated","title":"Animated"}],"license":{"slug":"cc0-1.0","name":"CC0 1.0 Universal","url":"https://creativecommons.org/publicdomain/zero/1.0/","attributionRequired":false},"contributor":{"username":"3dassets","name":"3D Assets","url":"https://3dassets.dev/u/3dassets"},"stats":{"fileSize":54404,"triangles":1148,"vertices":2547,"meshes":6,"materials":4,"textures":0,"animations":["trolley-open","trolley-close","hoist-open","hoist-close"],"boundingBox":{"min":[-13.600000381469727,-0.00005048347333769243,-3.3999181861250527],"max":[13.600000381469727,16.999935940936243,3.749408289816984]},"sizeMeters":[27.2,17,7.149],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-12T06:05:51.250Z","updatedAt":"2026-09-12T06:05:51.343Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\nimport { AnimationMixer } from 'three'\n\nlet mixer\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/37932/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n  mixer = new AnimationMixer(gltf.scene)\n  mixer.clipAction(gltf.animations[0]).play()\n})\n\n// Call from your render loop; deltaSeconds is time since the previous frame.\nfunction updateAssetAnimation(deltaSeconds) {\n  mixer?.update(deltaSeconds)\n}","r3f":"import { useGLTF, useAnimations } from '@react-three/drei'\nimport { useEffect } from 'react'\n\nexport function DockGantryCrane24MSpanShipyardAndDryDock(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/37932/v1/model.glb')\n  const { actions, names } = useAnimations(animations, scene)\n  useEffect(() => {\n    const action = actions[names[0]]\n    action?.reset().play()\n    return () => { action?.stop() }\n  }, [actions, names])\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/37932/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/37932/v1/model.glb\" alt=\"Dock gantry crane, 24 m span (Shipyard and Dry Dock)\" camera-controls auto-rotate autoplay></model-viewer>","blender":"# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.\nimport bpy\nbpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/37932/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.\n# Clips arrive as actions; play them from the Dope Sheet > Action Editor.","godot":"# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.\nvar packed := load(\"res://models/model.glb\") as PackedScene\nvar model := packed.instantiate()\nadd_child(model)\nvar player := model.find_child(\"AnimationPlayer\", true, false) as AnimationPlayer\nplayer.play(player.get_animation_list()[0])","unity":"// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,\n// or load it at runtime straight from the CDN:\nusing GLTFast;\nvar gltf = new GltfImport();\nif (await gltf.Load(\"https://cdn.3dassets.dev/assets/37932/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
