Typical cargo

Long or wide items loaded by forklift: building panels, pipes in frames, garden furniture, and goods that must be loaded and unloaded quickly.

In plain words

With the long side open, a forklift can place pallets anywhere in the container without working from the back to the front. This saves time and is useful for long or wide items that are hard to push in through the end doors. In the table, the door width is the side opening.

Open side containers are much less common than dry containers and are often supplied by leasing companies rather than shipping lines. Ask early about availability and price. Some models open on both long sides.

Example from real shipping

A building materials supplier ships 2.3 m wide insulation panels. Loading them through the end doors would be slow and could damage the panels. The forwarder sources a 20' open side container, and a forklift loads the panels from the side in under an hour.
