Basically, they are working on the container vessels.The materials they use are,'container lashing turnbuckle', 'container lashing bar', 'base corn', 'semi-auto twistlock'.
The materials for container lashing are usually bigger and heavier than conventional vessel's one.
The basic tools they use are,'unlocking pole for twistlock', turn-stick'.
Have you ever seen the inside of a container vessel?Have you ever imagined what is happening there? No?
OK, Let's go and have a look! This is one of the "on deck lashing".
The first container is hanging by the gantry crane.
Also, the lashers are ready to go now.
(photo.1)The box is just placed in the position. The lashers have been working on the container. They are putting on the lashing bars.
(photo.2)They have put the bars and turnbackle together. And they are tightening the turnbackles up now.
(photo-3)They are working on the 2nd tier boxes.As you can see, the lashers are working in such a small space.
(photo-4)They are putting the 3rd tier lashing now.
We are required to put the 3rd tier lashing as the wind lashing that the containers are placed on the edge of the decks.
In case of the end deck working, we must be careful for our safety. Because, the deck 's are more than 8m above the surface of the sea. This height is like the 4th floor of a normal building.
He is setting the semi-auto twist-locks on the land side. The twist-locks connect the containers vertically.
(photo-5)This is the inside of the container vessel. You can compare with the conventional vessel's cargo hold.The difference between the container and conventional ship is the "cell guide". The cell guide is the guide rail for placing during the handling. And in the voyage, they also work as the equipment of the lashing. (photo-6)This is also the photo of the cargo hold. As you can see, 7 high cube(9'6 feet) containers in a line. This cargo hold enough for 8 normal height (8'6 feet) box in a line.
