Unit load DEVICE

unit load DEVICE (short ULDs) pallets and containers , which are used, are to be loaded in order luggage, freight and post office on large-capacity aircraft. They make it possible that large quantities of transport property are bundled into large units. Their use leads to the fact that fewer units must be loaded, and they save ground personnel, time and expenditure for the dispatching enterprises.

Air freight container type AKH

table of contents


it gives 2 forms of ULDs: Pallets and containers. ULD pallets will were stabilized with aluminum plates with edges to engage designed over on the Frachtbüdelansätze too. ULD container, also admits as tons and bowls, is perfectly locked containers made of aluminum or a combination made of aluminum (edge) and plastic (walls), and depending upon the kind of the goods in it, can it to cooling units have inserted. Down are examples of frequent ULDs and their characteristics. Meanwhile also explosion proof containers were developed, were not created these to have it however yet to the routine employment in airplanes, which was predominantly also because of the price of the containers.

airplane compatibility

LD3s, LD6s and LD11s are suitable for Boeing 787, Boeing 777, Boeing 747, McDonnell Douglas MD-11, Lockheed L-1011 and all airbus of large-capacity aircraft. Boeing 767 due to its narrower trunk with LD2s and LD8s one loads. The less frequent LD1s was designed particularly for Boeing 747, but LD3s are used more frequently because of their Ubiquität in their place (she to have the same soil dimensions, therefore needs a LD3 equal much place as a LD1). LD7s become for Boeing 787, 777, 747, later models of the 767 (with the large door) and all airbuses used.

The exchange of certain ULDs between LD3/6/11 airplanes and LD2/8 airplanes is possible, if the freight must be conveyed fast to the next flight. LD2s and LD8s can be loaded both on LD3/6/11 of airplanes, but a large volume around loss develops.

ULD capacity

airplane loadings can of containers, pallets or a mixture of ULD types consist, depending upon simplicity. Down is a table with the maximum loading capacities of airplanes.

all ULDs is identified with their ULD number. A three-letter prefix identifies its type to differentiate followed of a serial number from 4 or 5 numbers around it also from the same type to and ends with a 2-Zeichen-Suffix around the ULD owner to identify. For example AKN means 12345 DL that it concerns a LD3 with the serial number 12345 with the owner Delta Airlines.
