  "description": "自動車工場用の独立した車輪付きエンジンクレーン。開いたH形の脚、折りたたみ部のヒンジとピン、斜め補強を持つマスト、伸長した角形ブーム、油圧ラム、ポンプレバー、短い鎖と空のフックを造形。脚やブームは固定配置で可動しません。エンジン、車両、吊り荷、吊り具一式は含みません。外観用の静的プロップで、荷重定格・実動作・安全認証を持たず、製作・揚重・操作・安全の指示を提供しません。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）0.960 × 1.924 × 1.676 m、27,868三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A standalone wheeled engine crane for automotive workshops. Its open H-frame has folding-leg hinge plates and pins, a braced mast, extended square boom, hydraulic ram, pump lever, short chain and empty hook. Legs and boom are fixed in the shown pose with no articulation. No engine, vehicle, suspended load or complete rigging kit is included. This static appearance prop has no load rating, functioning mechanism or safety certification and supplies no engineering, lifting, operation or safety instructions. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.960 × 1.924 × 1.676 m; 27,868 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
