Unit Load Devices (ULD)

A ULD (Unit Load Devices) is a device used to move cargo being shipped as airfreight. More specifically, a ULD is used to consolidate cargo in order to assist with the loading process onto an airplane.

The first three letters of a ULD code are perhaps the most important. They are used to identify the type, size and shape of the ULD. This information is vital in determining not only the type of cargo it can contain but also the aircraft it is compatible with

 

Unit Load Devices (ULDs) come in two forms: Containers and Pallets.

Both pallets and containers allow a large quantity of cargo to be bundled into a single unit, which can be used on wide-body aircraft and certain narrow-body aircraft.

Cargo on pallets are secured by a net, which is attached to the pallet’s rim. Containers, also known as cans and pods, are typically lightweight structures comprising a base, a frame with side and roof panels, and a fabric or solid door. There are many different types of containers. Some are collapsible, some are insulated, and others are ventilated or refrigerated and so on.
