A gooseneck apparatus for connecting a lowboy trailer to a truck-tractor includes a horizontal section having a king pin connection and a vertical section. The horizontal section includes side rails. A hydraulically actuated lift mechanism is provided within the horizontal section for positioning the gooseneck apparatus with respect to the tractor bed. The vertical section includes a pair of open-top side box-like sections aligned beneath each side rail, and a pivot support connects the upper forward portion of each to the side rail. The pivot support axis is in the horizontal plane inclusive of the ling pin. Trailer lift cylinders are pivotally connected to the vertical section and side rails and are essentially vertically oriented in the transport position. The lift pivot connections are located with respect to the forward main pivot support to provide the necessary arcuate movement of the vertical sections. A forward slotted plate depends below a bottom support wall of each vertical section. The trailer includes a coupling pin aligned with the plate opening. A horizontal coupling includes a pneumatic operated vertical coupling pin interconnected to pin opening in trailer. The vertical sections include pivotally mounted vertical load walls aligned with the side rails and pivoted outwardly to a release position with the side rail dropping into the vertical section and permit collapse of the gooseneck apparatus and the trailer bed to allow separation of the trailer and gooseneck apparatus. The pivot connections between the horizontal and vertical sections and particularly the forward pivot connection with respect to the truck tractor connection are located with respect to each other to provide proper motion and movement in the coupling and decoupling of the trailer bed without requiring and creating relative movement of the tractor and trailer.
