ビデオの説明:
This short presentation tells the story behind the DH80-7 excavator swing gearbox design and its intended use cases. You'll see a detailed breakdown of the core components including sun gear, planet gears, ring gear, and built-in brake system. We demonstrate the working principle from hydraulic input to final rotation output, and explain common operational faults like abnormal noise, oil leakage, and slow slewing - helping equipment managers understand maintenance needs and maximize uptime in construction and mining applications.
