A pin box is provided having a removable and reversible hitch. The removable hitch has a kingpin end and a ball end. The pin box has a skid plate with an aperture with a receiver that can receive and affix the removable hitch. The skid plate is reinforced to the receiver to carry the load when the ball end of the removable hitch is being used. A pin is slidable between a locked position where the removable hitch is retained and an unlocked position where the removable hitch is removable. The pin extends through an aperture in the removable hitch to affix the removable hitch to the pin box.

A parked freight trailer stabilizer and restraint comprising: (a) a kingpin receiver configured to lock onto a kingpin of a parked freight trailer; (b) a jack operatively coupled to the kingpin receiver, the jack repositionable between a retracted position and an extended position; (c) a tail hold operatively coupled to the kingpin receiver, the tail hold repositionable between a stowed position and a restraining position, the tail hold configured to engage a ground mount; and, (d) a transport receiver configured to engage a transport vehicle.

A lock for a gooseneck style trailer may present a tow-ball interface on a base plate with an associated rod interface. The rod may be inserted through one of a plurality of holes along a circumference of the base plate so as to also interface with structure on the trailer. The rod then may be locked into position with a locking mechanism.

A trailer lock can be used as an anti-theft device to secure a mating feature of a trailer, such as a king pin, against unauthorized hookups by tractors. The trailer lock can include a base plate for mounting on a wall of the trailer; a swing bar pivotally connected to the base plate; and an engagement bar pivotally connected to the swing bar, which engagement bar includes an engagement feature, such as a ring, capable of fitting to the mating feature of the trailer. When the engagement feature is fitted to the mating feature of the trailer (for example, when a ring is placed over a king pin), it can prevent the mating feature from engaging a corresponding mating feature of a tractor, such as a fifth wheel.

A method for locking and releasing a securing device of a vehicle coupling of a vehicle includes switching the securing device between a locked state and a released state by a control command output by an authorization unit where the authorization unit outputs the control command after receiving an initiation command transmitted to the authorization unit by an interface and where a wireless communication interface and a local physical interface are useable as the interface. Sensor data, generated by a sensor that monitors surroundings of the vehicle, is transmitted via the wireless communication interface to a control center. The initiation command is transmitted to the vehicle by the control center via the wireless communication interface as a function of the sensor data. When there is no communication connection between the control center and the vehicle, it is only possible to output the initiation command via the local physical interface.

A kingpin locking system for securing a kingpin on a trailer to a tractor is provided. The system comprises a C-shaped member having a main body portion, a first jaw portion, and a second jaw portion. A first spring member is mounted between the center portion and the first jaw portion with the first spring member allowing the first jaw portion to move in a general direction toward and away from the second jaw portion. A key mechanism activates a locking mechanism to lock the first and second jaw portions together and deactivates the locking mechanism to unlock the first and second jaw portions. Upon positioning the C-shaped member about the kingpin and moving the first jaw portion into contact with the second jaw portion, the key mechanism activates the locking mechanism thereby securing the first and second jaw portion together and securing the trailer to the tractor.
