The upper slews and the hook hoists with it. Overall 4.40 by 13.52 by 11.96 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 tracks on the ground; it rests on y=0 and the boom rakes toward -Z, so the crane is turned to face the lift. The rubber pads, the boom pendants and the wire rope are modelled solid: a track is a chain of links and rope is a soft body, and neither is reachable with a rigid node transform. Rigid node-transform clips: open, close and slew. 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-crawler-cr-1e80c332","cdnUrl":"https://cdn.3dassets.dev/assets/37934/v1/model.glb","downloadUrl":"https://3dassets.dev/download/shipyard-and-dry-dock-shipyard-and-dry-dock-crawler-cr-1e80c332","thumbnailUrl":"https://cdn.3dassets.dev/assets/37934/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/37934/v1/poster.webp","blurhash":"UBBDGy%K02E4ay9HM|~T9KIq?X?F-,%KbI9c","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":40884,"triangles":836,"vertices":1884,"meshes":5,"materials":4,"textures":0,"animations":["open","close","slew"],"boundingBox":{"min":[-2.20012814027184,-0.00009339215259440703,-8.5],"max":[2.20012814027184,13.52161881005567,3.4600000381469727]},"sizeMeters":[4.4,13.522,11.96],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-12T06:05:52.517Z","updatedAt":"2026-09-12T06:05:52.617Z","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/37934/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 CrawlerCraneWithLatticeBoomShipyardAndDryDock(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/37934/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/37934/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/37934/v1/model.glb\" alt=\"Crawler crane with lattice boom (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/37934/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/37934/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
