Lift devices for containers

A connection structure (25.6) for use with a container (5) with a mounting block (7, 8), wherein the mounting block (7, 8) comprises an elongate mounting hole (8.2), the connection structure (25.6) comprising:

• a flange (25.6) comprising:
• a threaded hole (25.6-3) that defines a bolt axis (25.6-4);
• a rotational plane (25.6-5) perpendicular to the bolt axis (25.6-4);
• a first (obstruction) portion (25.6-1) shaped to:
• pass through the elongate mounting hole (8.2) in a first rotational orientation within the rotational plane (25.6-5);
• and
• be prevented from passing through the elongate mounting hole (8.2) in a second rotational orientation within the rotational plane (25.6-5);
• a second (seating) portion (25.6-2) shaped to seat into the elongate mounting hole (8.2) when the flange (25.6) is in the second rotational orientation, and thereby preventing rotation of the flange (25.6);
• and
• a bolt (25.5) disposed in the threaded hole (25.6-3);
• wherein the flange (25.6) comprises:
• an insertion configuration, wherein the flange (25.6) is in the first rotational orientation, and the first (obstruction) portion (25.6-1) and the second (seating) portion (25.6-2) pass through the elongate mounting hole (8.2);
• a seating configuration, wherein the bolt (25.5) is rotated (25.10) to place the flange (25.6) in the second rotational orientation (25.9), seating the second (seating) portion (25.6-2) into the elongate mounting hole (8.2) and preventing the rotation of the flange (25.6);
• and
• a secure configuration, wherein the bolt (25.5) is rotated (25.9), causing the flange (25.6) to (1) move along the bolt axis (25.11) and (2) press against an interior wall of the mounting block (8.2-1).
