ABSTRACT:
A trailer assembly is provided with means to lower the trailer platform to the ground where the gooseneck may be detached from the platform to facilitate loading. A rotatable detachable connection of the gooseneck to the platform is provided by interlocking hooks on the gooseneck frame and the platform. Raising and lowering of the platform is accomplished by hydraulic rams located in the gooseneck which, through a force amplifying linkage apply force to an arm, pivotally connected to the gooseneck, and bearing on the platform at a location remotely to the rear of the forward connection. A force couple is created about the interlocking hooks resulting in relative rotation of the platform and gooseneck and raising or lowering of the platform. The position of the gooseneck and platform is maintained for travelling by compression blocks which bear against the gooseneck frame and the arm isolating the raising and lowering mechanism from loads. A rod, which engages the platform frame and the arm restrains the gooseneck in the event of platform load reversal.
