ABSTRACT:
An improved tilt-bed trailer constructed of light weight and durable materials is disclosed. A trailer frame with an associated rotatably interconnected tongue is affixed with a tongue release and retention mechanism that slidably engages a portion of the tongue and a portion of the frame to hold them in a fixed position when engaged and to allow the frame to pivot with respect to the tongue when disengaged. The mechanism utilizes gripping members to cooperate with ridges on the tongue.
