Fuwa landing gear manufacturers

Selecting the right capacity is critical for safety. You must distinguish between Static Load (the maximum weight the gear can support when stationary, typically 80 tons) and Lifting Capacity (the weight the gear can actually raise, usually 24-28 tons). For heavy-duty semi-trailers, always ensure the lifting capacity exceeds your maximum expected tongue weight to prevent mechanical failure.

Focus on the gearbox design; high-quality units feature an internal or external gearbox with high/low speed ratios for efficiency. Verify the travel length (standard is often 17 inches or 19 inches) to match your trailer height. Additionally, ensure the mounting plate dimensions are compatible with your trailer chassis to avoid costly structural modifications.

The outer and inner legs should be made of high-strength alloy steel. To prevent corrosion in cross-border shipping and long-term use, specify electrophoretic coating (E-coat) or powder coating. For the internal screw mandrel, ensure it is forged steel with a high-precision thread to guarantee smooth operation under pressure.

Suppliers should ideally hold ISO/TS 16949 or IATF 16949 certifications, which are the gold standards for the automotive and trailer component industry. Request salt spray test reports (minimum 96 hours) and cycle life test data to ensure the gear can withstand thousands of extensions and retractions without failure.

Fuwa is a highly recognized brand, making it a target for counterfeits. Always verify the supplier's authorization or factory credentials. Look for stamped serial numbers and official logos on the gearbox. Conduct a third-party factory audit via services available on Made-in-China.com to ensure the manufacturer has the technical capability to produce genuine-spec components.

Landing gear is heavy and dense, making sea freight (LCL or FCL) the most economical choice. Ensure the supplier uses fumigated wooden pallets and heavy-duty steel strapping. To prevent rust during long sea voyages, require the use of VCI (Vapor Corrosion Inhibitor) bags or a thick layer of marine-grade grease on all moving parts.

Use Secured Trading services on Made-in-China.com to protect your funds. Negotiate a 30% deposit and 70% balance payment after a successful pre-shipment inspection (PSI). Ensure the contract includes a 12-month warranty period and clearly defines the process for replacing defective units, including who covers the international return shipping costs.
