Abstract
The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “A twistlock and corner casting together form a standardized rotating connector for securing shipping containers. The primary us es of twistlocks are for locking stacked containers on a container ship. “Many types of twistlocks, such as manual twistlocks, semi-automatic twistlocks or fully automatic twistlocks, can be used between the containers in a stack. “In the stack” means that there will be a container both above and below the twist lock. Each type of twistlock has many different structures. It is tedious and da ngerous work to install or remove the twistlock on or from the container.
