Shipping containers have revolutionized the way goods are transported around the world. Before the advent of shipping containers in the 1950s, cargo was typically loaded and unloaded by hand, making shipping a slow and labor-intensive process. With the introduction of standardized shipping containers, goods can be loaded and unloaded quickly and efficiently, reducing the time and cost of shipping.
Commonly Used Shipping Containers
There are several types of shipping containers available, but the most commonly used ones are the standard, high cube, flat rack, and open top containers. The most popular container sizes are 20-foot, 40-foot, and 45-foot containers. Each type of container is designed to accommodate different types of cargo, and the container sizes vary depending on the amount and size of the cargo being transported.
Internal Packing Sizes and Weight Loadings
It's important to know the internal packing sizes and weight loadings of shipping containers to ensure that you can transport your cargo safely and efficiently. The maximum weight loadings for each container size vary, and it's crucial to make sure that you don't exceed the weight limit. Exceeding the weight limit can result in safety hazards, damage to the cargo, and additional shipping costs.
Note that the actual internal dimensions and volume may vary slightly depending on the manufacturer and specific model of the container. It's important to verify the specifications with the container supplier before making any decisions about cargo loading and transportation.
Specialized Containers
In addition to standard containers, there are also specialized containers that are designed for specific cargo types. For example, refrigerated containers are used to transport perishable goods that require temperature control, while tank containers are used to transport liquids and gases. Open-side containers are used for cargo that requires easy access from the side of the container.
