Cargon

Each traverser carries two flat trays known as "cargons". These have wheels set into their undersides, and two cargons — each roughly 16 ft. long and holding some three tons of miscellaneous freight — together fill the hold of a Bristol Freighter.

Freight shippers are being urged to use trucks without trays, so that the cargon itself provides a combined tray and load that can be replaced by one withdrawn from an incoming aircraft.

For all SAFE'S freight-carrying, the basic equipment is the cargon (for New Zealand Railways) and the cargonette (for NAC). Both are made of lightweight aluminium, the cargonette being one quarter the size of the cargon.

The load is made up in the freight depot and stowed and tied down on flooring with rollers underneath, known as cargons. The complete load on its linked set of cargons is then transported to the aerodrome by road.

An unusual feature of the dairy is the use of 'cargons' — wheeled metal pallets that hold a stack of crates and enable them to be handled both in the dairy and at the depots without having to use fork lift trucks.

Engineers from New Zealand Government Railways then worked with SAFE to create the cargon system, a pallet and transfer system to speed up the loading and unloading process.
