Intermodal is a transportation method that combines multiple modes of transportation of cargo shipping. It is particularly effective for long-distance travel, saving up to 30% in fuel costs. The use of intermodal or ISO containers is crucial in the transportation industry to achieve strategic goals and manage traffic. It also promotes sustainability and enhances supply chain operations.
This blog post provides a thorough and concise guide on intermodal containers, covering different types, and potential advantages for your business.
What is an Intermodal Container?
Intermodal containers and ISO containers refer to the same type of freight containers that are designed to be easily transferred between different modes of transportation without having to unload and reload the contents.
The containers are made following the standards of the International Organization for Standardization (ISO), which ensures that they have strong structural integrity, can withstand various weather conditions, and have the appropriate size and durability.
ISO containers are designed with standard sizes so that they can be easily transported via rail, road, or sea. They come in two lengths, 20 feet, and 40 feet, with different width and height options. The most commonly available dimensions are 1 TEU, which is 20 feet long, 8 feet wide, and 8 feet 6 inches high, and 2 TEU, which is 40 feet long, 8 feet wide, and 8 feet 6 inches high. There is also a High Cube option, which is 20 feet long, 8 feet wide, and 9 feet 6 inches high.
The term TEU, which stands for Twenty-foot Equivalent Unit, refers to the standard unit used to measure a container’s capacity. This measurement is based on the volume of containers that are 20 feet in length. It is recommended for manufacturers have their containers inspected every 30 months to ensure their quality and standardization.
Intermodal Container Types
Dry Freight Intermodal Containers
The Dry Freight Intermodal Container, also referred to as a general-purpose container, is a type of intermodal freight container that is utilized for transporting a variety of manufactured goods and materials. It should be noted that there are two different door configurations available for this type of transportation.
- Dry Freight Intermodal Container with one set of double doors on one end
The Dry Freight Intermodal Container with one set of double doors on one end is the most popular choice for transporting goods across sea, land, or rail. These containers are designed with a secure locking mechanism that ensures the safety of your cargo during transportation. Moreover, these containers are also useful for storage purposes.
- Dry Freight Intermodal Container with doors on both ends/tunnel container
The Dry Freight Intermodal Container with doors on both ends, commonly referred to as a tunnel container, is very convenient because of its dual doors that facilitate loading and unloading from either direction. It is an ideal option for businesses that prioritize convenience when transporting cargo.
Refrigerated Intermodal Containers
Refrigerated Intermodal Containers, also called Reefers, are made of stainless steel and aluminum. They have a powerful electric cooling unit that maintains an insulated environment of R30. They have temperature control and are ideal for transporting perishable items over long distances because they can regulate the temperature from -15 to 65 degrees Fahrenheit to keep the goods safe.
Some refrigerated intermodal containers do not have a working refrigeration system and are referred to as “insulated non-working refrigerated intermodal containers. “They usually have double doors on one end and are also called “insulated containers” or “non-operating reefer containers (NOR).”
Open-top Intermodal Containers
An open-top intermodal container is a cargo box that lacks a metal roof and instead has an all-weather tarpaulin and extractable bows. It is ideal for the effortless transfer of large or tall items that typically require a crane for lifting. This container has a more extensive storage capacity than regular vans since it has a removable roofing system.
Open-side Intermodal Containers
An open-side intermodal container is similar to enclosed metal storage containers, except for one side which has bi-fold doors instead of a wall. These doors can be partially opened or removed completely as needed. This type of container is called a side-access container, full-side access container, or side-opening storage container.
Duo-Con Intermodal Containers
Duo-Con intermodal containers are a great choice for businesses that need a 10-foot storage space. These 20-foot containers can be easily divided into two 10-foot units by removing specific panels. The containers also come with front walls that need to be welded on to turn them into standard metal boxes, suitable for use as regular 10-foot shipping containers.
Tank Intermodal Containers
Tank containers, also known as intermodal ISO tanks, are customized stainless steel storage units that are designed to transport liquid materials such as gases. These tanks are safe for transportation as they are made according to international standards and are equipped with an ISO frame that makes handling easy, whether the material is hazardous or non-hazardous.
Intermodal Container Chassis
Intermodal container chassis are custom trailers designed to transport heavy containers, such as 20′, 40′, and 45′-foot sizes, as well as 53′ High Cube containers.
Benefits of Using Intermodal Containers
Save Time and Effort
Intermodal containers allow you to load your cargo and use the same container for transportation by sea, rail, or road. This eliminates the need for frequent loading and unloading, saving you time and effort. Additionally, using intermodal containers reduces crane time and truck turnaround time, making the transportation process quicker and more efficient.
Saving Costs
As stated previously, intermodal containers can save money by not requiring extra operations and avoiding empty miles. Therefore, many in the logistics industry consider ISO containers to be the most economical choice.
Higher Capacity
Intermodal transportation includes the rail industry, allowing for the transportation of bulk cargo all at once.
Dependable and Efficient
Intermodal transportation and the use of containers rely on reliability and effectiveness, which are crucial for a successful business. Compared to over-the-road (OTR) transportation, intermodal shipping is more efficient and faster, removing many roadblocks in the process.
Secure and Hassle-Free
Intermodal containers adhere to strict ISO guidelines and standards, ensuring that there is no risk of leakage or hazardous accidents. In addition, the implementation of IoT and big data in shipping enables real-time tracking of the entire journey.
