Container Loading Calculation Techniques and Methods

Container Loading Calculation Methods and Techniques

I. Container Loading Calculation Methods

1. Calculation of Cargo Volume

The volume of a container is generally calculated based on its internal dimensions, with the unit being cubic meters m³. Volume = Length × Width × Height. It should be noted that the actual internal dimensions of containers may vary slightly due to differences in production batches. During the loading process, we need to consider the shape coefficient of the goods, which is typically close to 1. If the goods are cylindrical in shape, the calculation will involve the use of a circular coefficient.

2. Coordination Between Door and Internal Dimensions

After determining the quantity of goods to be loaded, it is necessary to consider the coordination between the door and the internal dimensions of the container. Typically, the door of a standard container is located on one side of the container body, allowing for stacked goods up to approximately 2 meters in height. This must be taken into account during the loading plan.

3. Weight Distribution

To maximize cost savings and transportation efficiency, proper weight distribution is crucial. Generally, shipping companies set maximum loading weight limits for different types of goods. For example, the maximum weight limit for a 20-foot container is around 27 tons. When loading, it is necessary to allocate weights and volumes reasonably according to the size of the goods.

II. Container Loading Techniques

1. Avoid Over-height Loading

To make full use of the internal space of the container, it is recommended not to stack goods beyond the height limit of the container. If over-height loading is required, approval from the shipping company must be sought and obtained.

2. Proper Arrangement of Goods Placement

Based on the internal dimensions of the container and the position of the door, properly planning the placement of goods can effectively improve loading efficiency. For instance, larger-volume goods should be placed at the top and bottom of the container to reduce stacking height while ensuring safety.

3. Ensure Stability of Goods Stacking

To ensure the safety of goods during transportation, strict control over their stacking is necessary. Generally, lightweight goods should be placed on top, while heavy goods should be placed at the bottom. To avoid uneven loading, balance blocks should be placed in appropriate positions based on the actual center of gravity of the goods.

In conclusion, correct calculation methods and reasonable loading techniques are key to ensuring the safe and efficient transportation of goods. During the container loading process, we need to fully consider factors such as the volume, weight, and placement of goods, adhering to the regulations and requirements of shipping companies to ensure the smooth progress of transportation.
