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 are the same type of freight containers. They can be moved easily between ships, trains, and trucks without unloading. This is called intermodal freight transportation.
These containers meet International Organization for Standardization (ISO) rules, making sure they are strong, weather-resistant, and the right size.
ISO containers have standard sizes so they can be easily moved by train, truck, or ship. They come in two lengths: 20 feet and 40 feet, with different widths and heights.
The most common size is 1 TEU, which is 20 feet long, 8 feet wide, and 8 feet 6 inches high. Another common size is 2 TEU, which is 40 feet long, 8 feet wide, and 8 feet 6 inches high. There is also a High Cube size, which is 20 feet long, 8 feet wide, and 9 feet 6 inches high.
TEU stands for Twenty-foot Equivalent Unit. It is a standard way to measure a container’s size based on the volume of a 20-foot container. It is recommended that manufacturers check their containers every 30 months to make sure they are good and meet standards.
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, including heavy machinery, 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.
Intermodal containers offer versatile and efficient solutions for transporting goods across multiple modes of transportation, including sea, rail, and road. By understanding the different types of intermodal containers—such as dry freight, refrigerated, open-top, open-side, duo-con, tank containers, and intermodal container chassis—you can select the best option for your business needs. The benefits of using intermodal containers include time and cost savings, increased capacity, and enhanced security and efficiency. These containers adhere to strict ISO standards, ensuring the safe and reliable transportation of your cargo.
