What does the term "coil shifting" refer to in transportation?

The term "coil shifting" refers to the movement of unsecured cargo during transportation. This phenomenon primarily occurs when coils, which are often heavy and have a rounded shape, are not adequately secured within the transportation vehicle. When the vehicle experiences movement, such as during acceleration, deceleration, or cornering, these unsecured coils can shift from their original position, potentially leading to damage, hazards, or accidents.

Understanding coil shifting is crucial for ensuring the safety of the transportation process. Properly securing cargo, particularly heavy items like metal coils, is essential to prevent shifting and maintain the integrity of the load during transit. Recognizing the risks associated with coil shifting allows carriers and shippers to implement necessary precautions, such as using appropriate strapping and securing techniques to keep the cargo stable.

Notably, the other choices focus on different aspects of cargo handling and transportation that do not specifically capture the essence of "coil shifting" as it pertains to the risks associated with unsecured cargo.
