{"data":{"id":"8478","slug":"animated-mechanisms-kit-counterweight-platform-8d84da6e","title":"Counterweighted mast platform (Animated Mechanisms Kit)","summary":"Braced 4.8 m lattice mast with a head sheave, a railed working platform on one side and a stacked counterweight on the other, roped so they travel opposite each other.","description":"A 2.2 m base plate carries a five bay lattice mast with a head frame and a grooved sheave. The 1.5 m platform has three sided railing and an amber toe board; the counterweight is a 0.6 m block on a guide yoke. Overall size 2.2 x 5.08 x 2.32 m in metres, +Y up, +Z forward, resting on y=0. Node `platform` and node `weight` translate on Y in opposite directions; nodes `ropeP` and `ropeW` scale from the sheave axis at y=4.82. Clips: `idle` raises the platform 2.4 m and lowers the weight the same distance, then returns, over 6 s. Node TRS animation on named nodes only; no skinned rig, skeleton, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/animated-mechanisms-kit-counterweight-platform-8d84da6e","cdnUrl":"https://cdn.3dassets.dev/assets/8478/v1/model.glb","downloadUrl":"https://3dassets.dev/download/animated-mechanisms-kit-counterweight-platform-8d84da6e","thumbnailUrl":"https://cdn.3dassets.dev/assets/8478/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/8478/v1/poster.webp","blurhash":"U35}z3xt00IVt-RkI9%2?wRj8_xu_Nxu9EIU","category":{"slug":"props","title":"Props & Furniture"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"low-poly","title":"Low Poly"},{"slug":"animated","title":"Animated"},{"slug":"exterior","title":"Exterior"}],"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":46680,"triangles":840,"vertices":2520,"meshes":9,"materials":4,"textures":0,"animations":["idle"],"boundingBox":{"min":[-1.1000735454281085,0,-0.8199807671952601],"max":[1.1000735454281085,5.080023786664886,1.5000198370311595]},"sizeMeters":[2.2,5.08,2.32],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5 (1M context)","downloads":0,"publishedAt":"2026-09-06T13:56:50.933Z","updatedAt":"2026-09-06T13:56:51.278Z","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/8478/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 CounterweightedMastPlatformAnimatedMechanismsKit(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/8478/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/8478/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/8478/v1/model.glb\" alt=\"Counterweighted mast platform (Animated Mechanisms Kit)\" 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/8478/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/8478/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
