Container Twist Lock
In simple terms, Twist Lock is a mechanical locking device firmly fastened at the corners of a shipping container. These mechanical devices are used to secure containers on ships, semi-trailer trucks, and container trains. It also helps to lift containers by cranes and side-lifters. They are conical in shape and primarily serve the purpose of positioning and fastening containers during transportation in ships. It incorporates a rotating mechanism that secures itself into each corner casting of the containers, and are mostly used on the deck of a vessel.
These devices are strong, durable, and work efficiently in spite of long periods of exposure to extreme weather conditions that the containers undergo during long voyages and storage.
Types of Twist Locks:
* Standard Intermediate Twist Lock
* Semi-automatic Twist Lock
* Fully automatic Twist Lock

Semi-automatic Twist Locks are used between two containers to join and secure them in place.
