Utility arm apparatuses for securement to a kingpin of a fifth wheel coupling of a trailer and related methods are provided herein. A utility arm apparatus can include an elongate body having an attachment end and a utility end. The attachment end can include a recessed portion for receiving a neck portion of a kingpin of a fifth wheel coupling secured to the trailer such that the utility end extends outward from the kingpin past an end of the trailer. The utility arm apparatus can further include a utility device secured to the utility end of the elongate body such that the utility device is positioned past the end of the trailer when the attachment end of the elongate body is secured to the kingpin.

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 plug-in coupling system for a commercial vehicle includes a primary coupling device having a plug console with transmission contacts that point in a plug-in direction, a secondary coupling device having a connection console configured such that the plug console and the connection console are connected to one another so that information and/or energy can be transmitted between the plug console and the connection console, or disconnected from one another where no information and/or energy can be transmitted between the plug console and the connection console, and a locking device is configured to move between a locking position to prevent a transfer from the coupling position to the disconnecting position and a release position to permit a transfer from the coupling position to the disconnecting position.

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.
