Passenger stair

When procuring passenger stairs, the most critical factor is the service height range, which must be compatible with the aircraft types in your fleet (e.g., 2,400mm to 5,800mm for wide-body aircraft). You should prioritize units with hydraulic telescopic systems for smooth height adjustment and anti-slip aluminum alloy treads to ensure passenger safety in all weather conditions. Additionally, verify the load capacity, which should typically support at least 75-80 passengers simultaneously or approximately 450kg per square meter.

The choice depends on your airport's operational frequency and budget. Towable stairs are cost-effective for low-traffic regional airports but require a tractor. Self-propelled (motorized) stairs, available in diesel or electric (lithium battery) versions, offer the highest efficiency for busy hubs, allowing for rapid positioning. Electric models are increasingly preferred to meet ICAO green airport initiatives and reduce long-term maintenance costs.

All units must strictly adhere to IATA AHM (Airport Handling Manual) standards, specifically AHM 910, 913, and 915. Ensure the product has CE certification or meets ISO 6966-1/2 for aircraft ground support equipment. Key safety features should include interlock systems (preventing movement while the stairs are raised), emergency manual pumps, and protective rubber bumpers at the platform edge to prevent fuselage damage.

To ensure a lifespan of 15-20 years, look for suppliers that use hot-dip galvanized steel frames or high-grade anti-corrosion coatings to prevent rust. Regular maintenance should focus on the hydraulic cylinders, stabilizer jacks, and braking systems. Choosing a supplier on Made-in-China.com that provides a comprehensive spare parts kit and detailed technical manuals is essential for minimizing operational downtime.

For high-value GSE (Ground Support Equipment), always mandate a Pre-Shipment Inspection (PSI) by a third party like SGS or Intertek. Request a video factory audit and a functional test report showing the stairs operating at maximum extension. Using Made-in-China.com's Secured Trading services can provide an extra layer of payment protection until the shipping documents are verified.

Passenger stairs are bulky and often classified as OOG (Out of Gauge) cargo. To optimize costs, inquire if the supplier can ship the unit in SKD (Semi-Knocked Down) condition to fit into standard 40HC containers. If shipped fully assembled, you will need Roll-on/Roll-off (RoRo) or Flat Rack containers, which incur higher freight costs. Ensure the Incoterms (e.g., CIF vs. FOB) clearly define who is responsible for specialized crane loading at the port.

Focus your negotiation on warranty extensions and after-sales technical support rather than just the lowest unit price. A 2-year warranty on core hydraulic and electrical components is a strong indicator of manufacturer confidence. Additionally, ask for customization on the canopy or livery colors to match your airline's branding, which many top-tier manufacturers will include for bulk orders of 3 units or more.

Since self-propelled stairs contain engines or large batteries, you must ensure the supplier provides a Certificate of Origin, MSDS (Material Safety Data Sheet) for batteries, and EPA/Euro 5 emission certificates for diesel engines. Failure to provide these can lead to heavy fines or seizure at customs. Always confirm the HS Code (typically 8428.90) with your local customs broker before the vessel departs.
