What Is A Container Twist Lock Used For?

Twist locks and corner castings combined make a standard rotating connector used to secure shipping containers. Their main uses include locking a container in place on semi-trailer trucks, container trains, or container ships, and for lifting containers either by side lifters or container cranes. Developed by transport engineer Keith Tantlinger, twist locks aim to make the world of trade and transport easier and more efficient. Since it can take months before a container can be inspected again, the major advantage of this device is that it doesn’t need regular maintenance to function effectively. Even after being exposed to weather for a long time, a container twist lock makes a container as simple to move as ever. But, when corrosion is extensive (to the point it’s visible,) twist locks can degrade and make it dangerous to move the crate.
