Which of the following is an example of a securing device?

Twistlocks are a type of securing device that are specifically designed for the purpose of securing containers to chassis or within stacking structures in intermodal transport. They play a crucial role in ensuring that cargo containers remain safely attached to the chassis during transit, preventing any unintended movement that could occur on the road.

Twistlocks typically integrate into the design of chassis used in freight transport and feature a locking mechanism that engages with the container's corner fittings. This ensures stability and security, which is vital for safely transporting goods over long distances. The use of twistlocks helps compliance with international shipping standards, thereby further emphasizing their importance in the logistics and transport industry.

While other options may also refer to securing items, twistlocks are uniquely tailored for the requirements of containerized cargo, distinguishing them as the correct example of a securing device in this context.
