Unit Load Device/Airfreight Containers
Also known as ULD’s, unit load devices are pallets or containers used to load luggage, freight and mail on an aircraft. They enable cargo in large numbers to be arranged or bundled into one single unit. Since ULD’s lead to a decrease in how many units there are to load, it saves ground crews time and effort and help to avoid delayed flights. Each one is provided with an individual packing list, also known as manifest, so that all the contents can be tracked. ULD’s come in two forms: pallets and intermodal containers. Pallets are made of aluminum, while containers (known as cans or pods) are made of a combination of aluminum (frame) and lexan (walls). Some containers may feature built-in refrigeration units.
