III. Solutions when transporting OOG cargo

Usually, to transport items with super-heavy dimensions and weight, shippers often pack into the flat rack or open-top containers to safely transport goods during the trip.

Flat rack containers are a type of container that manufacturers provide to units such as shipping lines and shippers to carry goods of large size, bulky, and very heavyweight, exceeding the limit of normal containers.

The main feature of this type of container is that it has a rather thick steel floor for carrying super-heavy cargo. They are flexible with oversized cargo, disassembled, and securely assembled into flat rack containers.

This type of container is designed with two open walls and an open roof. Like other types of containers, flat rack containers are divided into 2 types, 20″ and 40″:

The following favorable specifications 20” flat rack container:

Outer Dimensions: Length: 6.06m, Width: 2.438m, Height: 2.927m

Weight of boxers: 2.75 Tons

Maximum allowable cargo weight: 31,158 tons

The following favorable specifications 40” flat rack container:

Outer Dimensions: Length: 12,192, Width: 2.438m, Height: 2,591m

Weight of boxers: 6.1 Tons

Maximum allowable cargo weight: 38.9 tons

Open top container: This is a type of container used by manufacturers to transport and pack oversized items that other types of containers cannot do. This type of container has an open-top design, to transport items that are oversized in height. This type of container is also divided into 2 types 20” and 40”.

IV. Additional cost

For oversized and overloaded goods at the yard:

– In case of packing/unloading goods with sizes exceeding the regulations of standard containers, forklifts must be used (from 5 tons to 20 tons): The charge for loading/unloading is agreed upon by the port with the customer but not 300% lower than the normal closing price.

– In case of packing wrong specifications, wrong load, difficult to load and unload, collect the customer according to the unit price agreed with the customer but not lower than 400% of the normal loading and unloading unit price.

– In case the port’s loading and unloading vehicles cannot perform, they must hire an outside crane, and collect the customer according to the unit price agreed with the customer equal to the normal loading and unloading unit price plus the crane rental unit of the satellite unit, but must not be lower than 400% of the normal loading and unloading unit price.

However, this service fee depends on each port and will be regulated differently, so you need to learn carefully about this surcharge to have the best preparation.
