Container transportation is the safest way of modern cargo transportation. Safety is the "lifeline" of container transportation. Therefore, the container carrying more than ten tons of cargo must be connected and fixed with the vehicle body through a special lock. Semi-trailer vehicles engaged in container transportation are required to be equipped with the twist lock to secure the container.
A twist lock is a standardized rotating connector for securing shipping container. The semi trailer container twist lock main function is locking a container into place on container ship, semi-trailer truck or or railway container train; and for lifting of the containers by container cranes and side lifters.

For the international container specifications, there are: 20-foot container and 40-foot container, 40-foot high container and 45-foot high container. According to different container specifications, transport vehicles are equipped with a corresponding quantity of twist locks, usually 4, 8, 10, or 12 pieces twist lock. A semi-trailer can be equipped with twist locks of the same type, or different types of twist locks can be used together, all for the purpose of ensuring that the container is tightly connected during transportation.
There are many ways to connect the container twist lock to the trailer body. Some are directly welded to the vehicle body. The lock head can only rotate but cannot move longitudinally. This is called a fixed type;
Some twist locks are fixedly connected to the vehicle body through a bracket, the lock head can not only rotate but also longitudinally stretch, and when not in use, the lock head can be lowered below the bearing surface to suit different standard box types. This type is called lift type;
Some twist locks are hinged on the vehicle body or made to be movable, so that the fastening position can be adjusted, thereby greatly improving the utilization rate of the vehicle;
When the container is hoisted onto the semi trailer loading surface, the corner fitting hole at the bottom of the container just falls at the position where the twist lock is installed. By rotating the handle of the twist lock, the lock head will be fixed at a specified corner position (usually 90 degrees or 70 degrees) ) To make the twist lock in a locked state. For the lift type twist lock, push the handle longitudinally to raise the lock head, extend into the inner cavity of the bottom corner piece of the container, and then rotate to a specified angle to lock the corner of the container. Some swivel locks are equipped with a tightening device. By tightening, the lock head can press down on the bottom surface of the inner cavity of the corner piece to prevent the corner of the box from lifting, which ensures that the locking is more secure and reliable.
