When sourcing used garbage trucks from Japan (such as ISUZU, HINO, or FUSO), you must prioritize the Compactor Mechanism (press-type vs. slider-type) and the Discharge System. Check the Compression Ratio (typically 3:1 to 5:1) to ensure operational efficiency. Verify the Engine Model and Emission Standards (e.g., Euro 4 or Euro 5 equivalent) to ensure the vehicle meets your local environmental regulations. Additionally, inspect the Hydraulic System for leaks and the Chassis Rust Condition, as Japanese vehicles are often exposed to coastal humidity.
