Twist locks are mechanical devices used to secure two objects together, commonly found in shipping containers and trailers. They operate by twisting a handle or lever, which engages a locking mechanism that holds the items firmly in place. This design ensures that the contents remain secure during transport. These locks are often made from durable materials like steel to withstand harsh conditions. Twist locks are essential for maintaining safety and stability in logistics, as they prevent accidental openings and potential damage to cargo. They are widely used in the shipping industry, particularly with shipping containers and intermodal transport.
