Section 2: Using Cargo Containers
Cargo containers are not only used to move goods but to do so efficiently, safely, and by optimizing the entire supply chain. In this section, we explore the practical aspects of using these containers, from loading and unloading to advanced tracking technologies that monitor them worldwide.
Loading and Unloading Containers
The efficiency of the global supply chain largely depends on the container loading and unloading process, involving both the physical movement of containers and the planning and execution to minimize damage and delays. For efficient packing, it is crucial to distribute the weight evenly within the container, placing heavy items at the bottom and center, while lighter items can be placed on top.
Additionally, every inch of space inside the container should be used to prevent movement during transit, using packing materials and security straps to fill gaps and secure items. Each item loaded into the container should be documented and verified against a packing list to ensure inventory management.
To secure the load within the containers, built-in locking mechanisms for the doors, ties, and supports should be used to prevent internal movement, and desiccants or moisture-absorbing materials should be used to control humidity and prevent water damage. It is essential to avoid common mistakes such as improper weight distribution, inadequate securing of items, and poor planning that can cause delays and additional repacking costs.
Transport and Handling
Once containers are packed and sealed, they are ready for the journey. Containers are designed for seamless transfer between ships, trains, and trucks, making multimodal transport possible. On ships, containers are carried by container ships equipped with cranes for loading and unloading. On trains, containers are transferred to rail cars designed for intermodal transport, offering a cost-effective alternative to truck transport. At both ends of the journey, trucks transport containers to and from ports and rail terminals, using chassis to facilitate quick transfer between modes.
For container handling, cranes are used at ports to move them between ships and the dock, forklifts and reach stackers to move containers within the port or terminal, and straddle carriers to lift and carry containers within the terminal, improving mobility and reducing the need for crane repositioning. Cargo security is ensured through unique security seals for each container, which should only be broken by the authorized recipient, and additional locking mechanisms for high-value loads.
Storage and Warehousing
Not all containers are immediately loaded onto a ship or delivered to a customer; many spend time in storage or warehousing facilities where they are kept secure and accessible. Short-term storage is done at the port or a nearby facility, designed for easy access and quick turnaround, while long-term storage requires good ventilation, regular maintenance checks, and security measures to protect containers and their contents from weather and theft.
For stacking and storing containers, stacking rules must be followed to allow containers to be stored several high, depending on their type and storage area requirements. The access and design of storage areas should allow easy access to each unit, organizing containers based on departure time or destination. Additionally, it is important to consider temperature control for sensitive loads and protection against moisture and extreme weather.
Container Tracking and Technology
The ability to track and manage containers globally is a key component of modern logistics. GPS tracking and RFID tags are fundamental technologies for monitoring the location and conditions of containers in real time. GPS tracking systems provide real-time location data, helping with route planning and risk management, while RFID tags allow for faster scanning and identification of containers at various checkpoints.
Container management software solutions enable companies to manage their entire container fleet, including features such as tracking, scheduling, and maintenance management. These solutions are often integrated with broader logistics platforms that include inventory management, order processing, and transportation management.
Future trends in container technology include integrating the Internet of Things (IoT) with sensors that monitor conditions such as temperature, humidity, and door openings, as well as increasing terminal automation with automated cranes and autonomous straddle carriers, improving efficiency and reducing human error.
