A locking system and method for a movable freight container door comprises an electronic module and a mechanical lock element. The mechanical lock element comprises a shaft, at least of portion of which is configured to be inserted through an aperture in the electronic module, across a door handle retention region, and into a cavity in the electronic module. The shaft is securely retained in the electronic module by moving a lock mechanism to a locked position. At least one magnetic field sensor in the electronic module is used to read the position of the shaft in the cavity by sensing or not sensing one or more magnets in the shaft. A wireless communication component in the electronic module wirelessly transmits magnetic field sensor information.

The present disclosure provides a hinge, a freight container that includes the hinge and a freight container that includes a locking rod and optionally the hinge. The hinge includes a locking pin, a first wing, a second wing and a first hinge pin that pivotally connects the first wing to the second wing. The hinge further includes a pair of hinge lugs each having a first set of surfaces defining openings through which a second hinge pin passes and at least one of the pair of hinge lugs having a surface defining an opening through which a locking pin reversibly travels.

A bar lock includes an upper strap and a lower strap that receives the bar. The upper and lower strap hingedly engage to hinge butts at an opening of a truck. The upper strap forms an upper cylindrical passage that receives the bar. The upper cylindrical passage includes an upper opening and a lower opening. An upper weld is between the upper opening of the upper cylindrical passage and the bar. The lower strap forms a lower cylindrical passage that receives the bar. The lower cylindrical passage includes an upper opening and a lower opening. A lower weld is between the lower opening of the lower cylindrical passage and the bar.

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.

A supplemental locking device particularly suited for use on a cargo container. The device consists of a three-sided channel, made of heavy-gauge steel that fits over the locking mechanism of a cargo container capable of being slipped over this locking system with the aid of oval cut slots on the sides that accommodate any horizontal members.

An inner lock of a door of a container is provided, in which the door of the container includes: a plurality of locking rods installed on an outer side of the door; a handle formed on the locking rods; a retainer which is coupled to the door and on which the handle is seated; and a handle hatch which is rotatably coupled to an upper side of the retainer and binds or releases the handle, and the inner lock includes a rotation shaft passed through the door and extended to an inner side and an outer side of the container; a plate coupled to the rotation shaft extended to the inner side; a lifting member rotatably coupled to the plate; and a locking bar coupled to a lower side of the lifting member to lock or unlock the door by being fixed to or separated from a lower frame, in which the handle hatch is coupled to the rotation shaft extended to the outer side such that the locking bar is manipulated by rotating the rotation shaft from the outer side of the door.

A railcar locking system that includes a railcar with a first radial door and second radial door. The first radial door includes a first keeper on the first radial door and a second keeper disposed above the first keeper on the first radial door. The second radial door includes a first hinge on the second radial door and a second hinge disposed above the first hinge on the second radial door. The second radial door further includes a locking rod that includes a first cam disposed at a first end of the locking rod and a second cam disposed at a second end of the locking rod. The first cam is configured to engage with a first lobe of the first keeper and the second cam is configured to engage with a second lobe of the second keeper when the locking rod is in the locked position.

The first radial door includes a first keeper on the first radial door and a second keeper disposed above the first keeper on the first radial door. The second radial door includes a first hinge on the second radial door and a second hinge disposed above the first hinge on the second radial door. The second radial door further includes a locking rod that includes a first cam disposed at a first end of the locking rod and a second cam disposed at a second end of the locking rod. The first cam is configured to engage with a first lobe of the first keeper and the second cam is configured to engage with a second lobe of the second keeper when the locking rod is in the locked position.

A cover for a handle of a cargo door to cover hasp elements and a lock. The cover includes a first housing with a first front wall, first side walls each having a front and rear edge, and a top end wall and define a first housing interior. A guide leg and a latch is disposed on the first housing. A second housing includes a second front wall, second side walls, and a bottom end wall that define a second housing interior. The second housing includes a guide socket configured to receive the guide leg and a catch configured to receive and retain the latch. The housing interiors define a cover interior that covers the hasp elements and an installed lock with one of the guide leg and the latch disposed behind the handle and the other of the guide leg and the latch disposed in front of the handle.
