Lift Devices for Containers

A connection structure is disclosed for use with a container having a mounting block with an elongate mounting hole. The connection structure includes a flange with a threaded hole that defines a bolt axis. A rotational plane is perpendicular to the bolt axis. The flange has an first (obstruction) portion constructed to pass through the elongate mounting hole in a first rotational orientation within the rotational plane and be prevented from passing through the elongate mounting hole in a second rotational orientation within the rotational plane. The flange also has a second (seating) portion constructed to seat into the elongate mounting hole when the flange is in the second rotational orientation, thereby preventing rotation of the flange. A bolt is disposed in the threaded hole.
