Empty-weight comparison
GCFP weight status: Engineering-calculated
Reference material: CFRP
Reference basis: Published individual specification
Reference weight depends on manufacturer, materials and configuration. Calculated or estimated weights are identified above. Maximum gross weight includes the container and cargo.
AVULD LD4 is part of Avimetal’s proposed collapsible graphene carbon fiber ULD range, designed to reduce empty-container weight and storage space. Contact Avimetal for development, manufacturing and partnership inquiries.
Supplied chart: Rectangular container; IATA code ALP; classification LD4; rate class Type 8. Chart internal volume 5.7 m³ (201 ft³ as printed); maximum gross 2449 kg (5399 lb as printed). Chart envelope labels 96 × 60.4 × 64 in. Imperial and metric figures are rounded and may differ.
Boeing 767, 777 and 787. ANA identifies B787 lateral loading at 2449 kg and longitudinal loading at 1587 kg for its reference configuration. The chart identifies ALP rather than DQP; reconcile exact code and geometry before claiming the same limits. Airbus and 777X applications require model-specific review.
Chart forkable variant codes: ALB, ALC, AWB, AWC. Forklift capability of the AVULD design remains to be.
Conventional empty-weight reference: ANA Cargo LD4 DQP, lower end of published tare range. ANA publishes 120–130 kg for its DQP LD4. Numeric reference uses the lower bound, 120 kg, not an average. Attachment calls LD4 ALP; ANA uses DQP. Exact model, coding and configuration must be reconciled before a final comparison. ANA internal volume is 5.5 m3; chart value 5.7 m3 is retained as a reference target. ANA door opening 2310 x 1480 mm is conventional reference only.
Aircraft scope: A320neo/A321neo (including LR/XLR variants) use reduced-height LD3-45W/AKH configurations where a container loading system is installed; the full-height 64 in ULDs in this catalog are not interchangeable with LD3-45. Boeing 737 MAX and Airbus A220 are not added as standard lower-hold applications for this catalog.
