A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The rated load capacity is 1.5–3.5 t, but this is a reference range. Confirm the exact capacity for your specific model and application with the manufacturer.
The operating pressure is 1.0–1.6 MPa. Ensure your loader's hydraulic system can supply this pressure. Verify with the manufacturer.
The IP rating is IP65 per IEC 60529, meaning it is dust-tight and protected against water jets. This indicates suitability for dusty and wet environments, but verify for your specific conditions.
Check the coupler width (200–400 mm) and locking pin diameter (30–50 mm) against your loader's arm spacing and attachment pin size. Always consult the manufacturer for compatibility.
