Abstract

Gooseneck trailer having a horizontally extending deck with a plurality of longitudinally extending frame members including outer side rails which extend along opposite sides of the deck, lower gooseneck beams rigidly connected the outer deck rails by couplings that can be selectively engaged and disengaged, elongated upper gooseneck beams pivotally connected to the lower beams, with one end of each of the upper beams being pivotally connected to a pulling vehicle, operating cylinders connected between the upper and lower beams for raising and lowering the lower beams and the trailer deck when the upper beams are connected to the pulling vehicle, and latches for locking the upper and lower beams in different positions relative to each other. Each of the latches has first and second elongated ratchet blocks disposed side-by-side with mating teeth along confronting edges of the two blocks and upper and lower ends of the blocks being pivotally connected to respective ones of the beams for movement longitudinally with the beams and laterally toward and away from each other, and actuators for pivoting the blocks to bring the teeth on the two blocks into and out of engagement with each other to lock the beams in the different positions.
