Floating j-hooks between two bushings in housing with a single piston

A lock mechanism for locking at least one door of a container in a closed position, the lock mechanism comprising:

• a body;
• a locking mechanism coupled to the body, the locking mechanism comprising:
• first and second members slidably coupled to each other to move relative to each other, and
• a latching mechanism configured to prevent the two members from moving relative to each other in at least one direction when the latching mechanism is in a locked state;
• first and second lock members, each of the lock members including a first end and a second end, the first ends of the first and second lock members protruding through the body, the second end of the first lock member being coupled to the first member of the locking mechanism, the second end of the second lock member being coupled to the second member of the locking mechanism, the first ends of the first and second lock members configured to engage portions of the container to lock the at least one container door in a closed position, the body being sized and disposed to support the first and second lock members to prevent rotation of the first and second lock members about points where the first and second lock members are attached to the first and second members of the latching mechanism;
• and
• a lock circuit at least partially enclosed within the body, the lock circuit comprising a lock controller coupled to the latching mechanism and configured to receive commands related to the operation of the lock mechanism, wherein the lock controller is configured to cause the latching mechanism to be in the locked state in response to the received commands.
