The “Other” category for Airport Ground Support Equipment (GSE) covers miscellaneous, specialty machines and carts that don’t fit standard classes like tugs or belt loaders. Items include potable water trucks, lavatory service carts, ground cooling units, maintenance stands, cable reels, and custom service trailers. These units are critical for turnarounds, often aircraft-specific, and buyers should verify compatibility, power type, and regulatory compliance before purchase.
Check service records, hours, electrical and hydraulic systems, connector types, structural corrosion, safety features, and whether fittings match the aircraft you service.
Use a heavy-equipment carrier experienced with airport gear, provide exact weights and dims, consider partial disassembly, secure export/customs paperwork, and insure the shipment.
Availability varies. Check OEM support and aftermarket suppliers. Many parts (filters, pumps, hoses) are generic, but aircraft-specific fittings and control modules may be scarce.
Perform a full inspection, change fluids and filters, test batteries and electrical systems, replace worn hoses and seals, treat corrosion, and confirm all safety interlocks.
Airports typically require maintenance logs, safety decals, emissions/noise compliance where applicable, operator training records, and proof that connectors and voltages meet airport standards.
