I. Tesla's Gigafactory: The "Future Lab" of Global Manufacturing
1.1 Scale and Efficiency Challenges
Data Comparison: Tesla’s Berlin Gigafactory spans 300 hectares (equivalent to 420 soccer fields) and produces 90 Model Y bodies per hour—three times faster than traditional auto plants.
Core Challenge: How to achieve precise, rapid material handling in vast spaces? Conventional forklifts and conveyors proved inadequate.
1.2 Strategic Role of Overhead Cranes
Load Requirements: EV battery packs exceed 500kg, while motors demand positioning accuracy within 2mm.
Tesla’s Solution: 32 intelligent double-girder overhead cranes form the factory’s logistical backbone, spanning from stamping shops to final assembly.
II. Decoding 5 Breakthrough Technologies in Tesla’s Custom Overhead Cranes
2.1 AI-Powered Dynamic Path Planning
