A remotely-engaging handle for a fifth wheel hitch system is provided. The remotely-engaging handle may comprise a body and a latching assembly that may be securely attached to the body and capable of engaging with a fifth wheel hitch. The latching assembly may comprise a locking member and an actuating member. The actuation of the actuating member may position a portion of the locking member from an unlocked position to a locked position. The locking member may comprise a latching arm rotating about a pivot point and a biasing member operatively attached the body. The biasing member may bias the locking member into a transitory position. In one embodiment, the actuating member may further comprise an electrically-operated button or a software-based interface. In particular embodiment, the locking member may further actuated by a solenoid and the connecting member may further comprise a wireless device.

A security lock system for a fifth wheel hitch is system that restricts access to the connection between a fifth wheel hitch and a truck bed. The system includes a receiver lock, a fifth wheel hitch, a first sleeve, a second sleeve, a lock engagement channel, and a key. The receiver lock shields a securing mechanism of the fifth wheel hitch. The receiver lock connects with a base frame of the fifth wheel hitch through the lock engagement channel. The first sleeve and the second sleeve uphold the receiver lock against the lock engagement channel. A retractable locking bolt and a locking assembly are connected to each other with the key. The retractable locking bolt and the locking assembly remain stationary as the retractable locking bolt includes a first tubular body and a first stopper, and the locking assembly includes a second tubular body and a second stopper.

A safety chain engaging device for a towing vehicle having a gooseneck hitch attached with a rail of the towing vehicle is shown and described. The safety chain engaging device may include a first bracket configured to be secured with the rail of the towing vehicle, and a second bracket attached with the first bracket, the second bracket including a plate member spaced from the first bracket. The safety chain engaging device may also include at least one safety chain engaging member secured with the plate member, where the safety chain engaging member is configured to be laterally spaced from the rail upon securement of the first bracket with the rail.

A system for immobilizing a semi-trailer kingpin on a transport vehicle includes a balance arm and a substantially horizontal rigid linking structure designed to guide the vertical movement of the receiving nacelle, hold it in position above the lifting system in a horizontal plane and take up the forces exerted thereon. The longitudinal rigid linking structure is hingedly linked to the receiving nacelle and to the transport vehicle in order to take up the longitudinal forces from same, and the balance arm includes preloaded springs that take up the forces exerted on the balance arm when the receiving nacelle is temporarily inclined relative to the horizontal plane. The lifting system for lifting the receiving nacelle is mounted pivoting on the railway unit at a pivot pin transverse to the longitudinal axis of the transport vehicle.

A safety apparatus for a fifth wheel coupling having locking jaws arranged to detachably couple to a trailer having spring applied air brakes, the fifth wheel coupling comprising a locking component that is moveable between a first position whereat the locking jaws are in a coupled state and a second position whereat the locking jaws are in a decoupled state, the safety apparatus comprising a pneumatic valve arrangement pneumatically coupled to both a constant air pressure supply and an air park brake supply that supplies pressurised air to the spring applied air brakes, and a mechanical actuator mechanically coupled to the locking component and configured to mechanically actuate the pneumatic valve arrangement when the locking component moves from the first position to the second position, thereby causing the pneumatic valve arrangement to block flow in an air park brake supply line for preventing the spring applied air brakes from releasing.
