About the LD-11
A full-width lower-hold container built to the ALP rectangular code, with a canvas door and a centre post that swings clear for loading.
The swinging centre post is the distinguishing feature: it opens the full width during build-up and then locks back to carry the structure in flight. A refrigerated version exists under the RWB, RWD and RWZ prefixes, fitted with a solid door.
What it carries
How it is built
- Full-width lower-hold unit, rectangular in section.
- The door is canvas, and the centre post swings clear so the full width is open during loading.
- The refrigerated version has a solid door and runs under the RWB, RWD and RWZ prefixes.
- Aluminium sheet panels on an extruded aluminium frame, kept as light as the structure allows because every kilogram of tare displaces revenue payload.
- A flat base plate with hardened edge rails that engage the aircraft's latch and roller system, so the unit locks into position without separate lashing.
- One or two sides angled to follow the curve of the fuselage, letting the unit fill the belly-hold cross-section rather than leaving dead space.
- A door that is either a canvas curtain with built-in restraint straps or a hinged solid panel, depending on the variant.
- Forklift channels on the variants marked forkable, so the unit can be handled by forklift as well as by dolly and loader.
Why it is used
- Fills the contoured belly space that loose cargo would waste.
- Loads and unloads in a single lift, which is what keeps aircraft turnaround times short.
- Restrains the cargo in flight, so individual pieces need no separate tie-down.
- Interchangeable between airlines and aircraft under the IATA ULD identification system.
What to check before booking
- Tare weight counts against the payload allowance — a heavier unit carries less cargo for the same rate.
- The load must stay inside the contour; anything above the profile will foul the hold and be rejected at build-up.
- A canvas door resists weather but is not a secure closure.
