A locking device for preferred securement to the locking bars located on the doors of shipping container. The device includes a main frame and two preferably J-shaped plates. The a hub portion along with a first plate define an first securement area for the locking device to a first locking bar and a movable member along with a second plate define a second securement area for the second locking bar. A lock having a main shaft is inserted into the main frame and prevents the plates from being pulled outward. The lock is maintain in positioned by a solenoid which is disposed within a portion of the main frame in a closed/locked position preventing the lock and main shaft from being pulled out of the main frame. Upon receipt of an authorized remote command or password the solenoid is caused to be retracted allowing the main shaft to be move and freeing the two plates so that they can be pulled outwards allowing the locking device to be removed from the locking bars.

Cargo locks are general massive, virtually armor plate grade materials, cables, tags, etc. hung on the outside of any configuration of cargo containers, enclosed cargo trucks, vans, semi-trailers, boxcars, etc. A few internal cargo area lock systems have been offered but are cost prohibitive, massive and not practical for other than a stationary installation. This makes them impractical for cargo containers, boxcars, and most semi-trailers because they are rarely re-used by the same party who invested in an elaborate stationary lock system. In a further development of U.S. Pat. No. 9,683,394, virtually anyone can install this flexible Lock Mechanism and Electronic Control (LM&EC) and achieve a secured cargo area by making all locks inaccessible from the outside. Similarly, the LM&EC system can be readily removed for reuse elsewhere or its access and control components modified to adapt to the reuse application or improve security for the present application.

The current disclosure relates to a tank trailer for transporting meat packaging by-products. The tank trailer has a cylindrical body having a sloped rear end. An opening is formed in the sloped rear end, and a gate selectively blocks the opening. A locking mechanism is provided to securely lock the gate to the cylindrical body, thereby sealing the cylindrical body. The sloped rear end forms a chute through which meat by-products can be poured. The chute extends for a distance rearwardly of the trailer's rear wheel assembly.

According to some embodiments, an apparatus for railcar doors comprises a locking plug configured to be disposed within a square key hole. The locking plug comprises a front portion defining a recess having a recess shape. The apparatus comprises a key element. The key element comprises a key element shaft having a shape corresponding to the recess shape. The key element is configured to be inserted into the locking plug and to transfer a torsional force from the key element to the square key hole. In particular embodiments, the locking plug may comprise a back portion. The locking plug is disposed within the square key hole by a weld connecting the back portion of the locking plug to a portion of the square key hole.

Disclosed is a closure for a door of a shipping container. The closure includes a housing, an outside handle pivotally mounted relative to the housing, an inside handle pivotally mounted relative to the housing, and a catch connected to the inside handle. The closure is configured so that movement of the inside handle between a first position and a second position causes corresponding movement of the catch. A locking mechanism can releasably fix the inside handle relative to the outside handle, such that when in a locked position rotation of the outside handle causes corresponding rotation of the inside handle and when in an unlocked position the inside handle can be rotated independently of the outside handle.
