Problems solved by technology

But the twist locks of the prior art are all used to fasten and unlock the end corner fittings of the container, while the fastening positions of these non-ISO containers are in the middle of the box. Fastening will make it difficult to unlock the locked turnlock, which will bring great difficulties to transportation
Because the twist lock is not at both ends of the container, the twist lock of the prior art will not be able to be opened, that is, after the ultra-long container is transported to the port of destination by a container ship, it will not be able to unload the ship because it cannot be unlocked
