What are floor slots in a 20ft container?

Floor slots in a 20ft container are designed to secure cargo and prevent shifting during transport. They are specifically designed to accommodate the feet of pallets, ensuring stability and safety.

How is dimensional weight calculated for a 20ft container?

Dimensional weight is calculated by multiplying the dimensions of the cargo in cubic meters by a dimensional weight factor, which is 167 kg per cubic meter in this case. This helps determine the shipping cost based on volume rather than just weight.

What does the payload limit refer to?

The payload limit refers to the maximum weight that a 20ft container can safely carry. This figure is a planning guideline and should be verified with actual cargo weight to ensure compliance with safety regulations.

Each rectangle is one pallet slot on the floor. A second level uses the same footprint when the stackable toggle and the internal height both allow it.

Show the deterministic formula

Floor slots are a non-overlapping grid. The count is the better of one orientation, two orientations side by side, or repeated columns across the internal width. Euro 1200×800 mm resolves to 11 slots in a 20 ft dry container and 25 in a 40 ft dry container.

Cartons per pallet are the same grid on the pallet deck, times the layers that fit above a 150 mm deck and below the internal height, with 50 mm of clearance. Stackable freight uses two levels only when both levels fit.

Cargo volume is the carton cube. Volumetric weight is 167 kg per cubic meter. Billable weight is the greater of actual payload, including pallet tare, and volumetric weight. A per-cubic-meter rate uses the carton cube. A per-tonne or per-pound rate uses the billable weight. Payload limits are planning figures, not a carrier scale ticket.

Engineering notes

When loading a 20ft container with GMA pallets, it is essential to consider the dimensional weight and the specific limitations of the container. The dimensional weight for this container is calculated at 167 kg per cubic meter, which means that the weight of the cargo must be assessed against this metric to ensure compliance with shipping regulations.

Additionally, the payload limit provided is a planning figure, which should be used as a guideline for loading. It is important to verify the actual weight and dimensions of the cargo to avoid exceeding the container's capacity.
