Having done HK-Rotterdam sea trials, foldable FEU tested in Europe

4FOLD, world's first and only certified 40ft HC foldable container

• Sidewall-Roof lock: Used for locking the sidewall to the roof

• Sidewall-Endwall lock: Used for locking the sidewall with the endwall.

• Hammer lock: Similar to a lock used on a flatrack. As many standards parts as possible are used in the 4Fold container, to make it easy to maintain the 4Fold container worldwide.

• Toggle switch: With this lever it is possible to fold or unfold the container by only manipulating the roof.

• Forklift pockets: Because of limited height of some reach stackers, it is also possible to make a bundle of foldable containers with a forklifttruck

HOLLAND Containers Innovations (HCI), in partnership with CARU, is continuing to test its foldable 40-foot container, the "4Fold" that takes up a quarter of the space of one box when folded flat and stacked.

HOLLAND Containers Innovations (HCI), in partnership with CARU, is continuing to test its foldable 40-foot container, the "4Fold" that takes up a quarter of the space of one box when folded flat and stacked.

In the latest phase of the pilot programme, the "4Fold" boxes are being tested out on a route between Venlo in the Netherlands and Spain.

This follows a test at the end of last year between Hong Kong and Rotterdam, where they were unloaded from 8,500-TEU Cosco Prince Rupert, reports Lloyd's Loading List.

Empty containers on a ship can account for up to 50 per cent of its cubic load so the potential impact of "4Fold" is important not only in ocean freight but also for road and rail cargo haulage.
