Abstract: A gooseneck for connecting a tractor to a trailer. The gooseneck has a remotely controlled unit for operating the hydraulic and pneumatic systems that provide for moving a slidable king pin plate to different loading positions so as to balance the load for over-the-road transport. The gooseneck also has a pivotal rear end to assist in connection of the gooseneck to the trailer. A pivotal gooseneck stinger arm maintains the gooseneck in position for accurate placement during connection and disconnection of the gooseneck and trailer. All of the necessary movements for connecting and disconnecting the tractor and trailer can be accomplished remotely with a minimum of effort by the tractor trailer operator.
