Positioning assembly for positioning a container on a platform

A positioning assembly for positioning a container on a platform, the container having a corner fitting, said positioning assembly comprising:

• a first connecting rod having a container-connecting end that is adapted to be connected to the corner fitting of the container, and a threaded end section that is opposite to said container-connecting end;
• a second connecting rod having a platform-connecting end that is adapted to be connected to the platform, and a threaded end section that is opposite to said platform-connecting end;
• an elongated adjusting member with two opposite threaded ends that threadedly engage said threaded end sections of said first and second connecting rods, respectively, so as to permit tightening and loosening of said positioning assembly on the container and the platform, said adjusting member further having an elongated intermediate section extending between said threaded ends of said adjusting member;
• and
• a restricting member mounted on one of said first and second connecting rods and releasably engageable with said intermediate section when said one of said first and second connecting rods rotates relative to said adjusting member in a loosening direction due to undesired movement of the container on the platform, thereby preventing further rotation of said one of said first and second connecting rods relative to said adjusting member.
