Overview
ISO 6967:2006 - Aircraft ground equipment - Main deck loader - Functional requirements defines functional and safety-related requirements for self‑propelled main deck loaders used to handle aircraft unit load devices (ULDs) on international airport ramps. The standard sets minimum criteria for platform geometry, load capacity, conveyor systems, guide rails, stability and emergency features based on typical ramp conditions (surface, slope, weather, lighting, staff qualification). ISO 6967 is intended for manufacturers, operators and purchasers of aircraft ground equipment and complements other standards for safety and compatibility.
Key topics and technical requirements
- ULD base sizes and maximum gross mass: covers ULD sizes per ISO 8097 with representative base codes (A, M, R, G) and maximum masses up to 13 600 kg (30 000 lb) for the largest code.
- Platform geometry and movement:
- Front platform operating range: 2 100 mm to 5 600 mm (positioned at the aircraft door).
- Main platform elevating range: 508 mm to 5 600 mm.
- Loader must support two 2 438 × 3 175 mm ULDs on the main platform and one on the front platform simultaneously at maximum gross mass.
- Guide rails and stops:
- Retractable longitudinal guide rails with lateral adjustment to accept 2 438 mm and 3 175 mm widths (clearance +25 to +50 mm).
- Automatic ULD stops that coordinate with platform alignment and selected loading mode (end or side loading).
- Conveying system:
- Powered end and side loading capability; main-platform sections controllable individually or together.
- Conveying speed approximately 0.3 m/s (60 ft/min) and compliance with ISO 4116 for conveying surfaces.
- Mobility and stability:
- Drive capability up to 10 km/h unloaded; power steering; start-up on a 3° incline.
- Stabilizers required; operation and safety features to meet ISO 11995 stability objectives.
- Controls, safety and emergency:
- Driver and operator control locations, lighting, pictogram identification per ISO 7000, platform safety supports, emergency lowering, tow and brake‑release provisions, and emergency stop accessibility.
- Options: ULD rotation systems, automatic front‑platform compensation, extended height variants, enclosed cabins, and higher lift capacities.
Applications and users
ISO 6967 is used by:
- Manufacturers and designers of aircraft ground support equipment (main deck loaders).
- Airlines, ground handlers and cargo operators specifying procurement and operational requirements.
- Airport authorities and maintenance organizations ensuring ramp compatibility and safe operations.
- Procurement engineers and safety managers evaluating equipment conformity with international ramp conditions and interoperability with ULDs.
