A cargo containment structure swinging door system having one or more doors capable of swinging on double pivoting hinges such that said door or doors can be opened both outward of the cargo containment structure and inward into the cargo containment structure. The doors are capable of being secured by a latching mechanism in a closed position. The cargo containment structure may be a semi-trailer, cargo shipping container or straight van body of a cargo carrying truck.

Enhanced methods and systems for securing and monitoring cargo are described. Some examples provide a cargo monitoring system (CMS) that is configured to track, identify, and report about anomalous conditions or events related to cargo shipments. The CMS may include a software system that receives conditions information from electromechanical locks that secure cargo. The locks include data terminals that facilitate near real time monitoring of cargo. The electromechanical locks are installed on the bars or other mechanism (e.g., door rings) that lock the doors of a cargo container, train car, van door, or the like. The data terminals include logic that is configured to transmit to the CMS information about current conditions, such as location, temperature, lock status (e.g., open, closed), tamper attempts, and the like. The cargo monitoring system interprets the received information and performs various actions based thereon, such as to transmit alerts if anomalous conditions are detected.

A lock for permanent attachment to a movable freight container cargo door as a replacement for a prior art hasp or a prior art keeper. The lock is configured for permanent attachment to the cargo door using pre-existing hole locations for the prior art hasp or keeper. The lock comprises a straight shackle and a c-shaped lock body and is configured to retain a door handle between the shackle and the back of the c-shaped lock body. The shackle is locked into the lock body using a shackle lock element that engages with a groove in the shackle. The shackle groove is perpendicular to the shaft of the shackle. The shackle lock element is pressed into the groove using by one or more springs in linear direction that is perpendicular to the length of the shackle and perpendicular to the groove, and released from the groove through by a lock module, which could be a lock cylinder or an electronic lock module. Axial movement of the shackle to prevent the shackle from being completely removed from the lock body is accomplished by a screw in the lock body that rides into a longitudinal slot in the shaft of the shackle.
