Abstract
A tailgate closure mechanism for a tailgate hoist serves to move the tailgate from the horizontal position in which it functions as a platform to the upright position in which it functions as a gate. The closure mechanism includes a closing slide which is slidably mounted on at least one of the tailgate support slides and a connecting link that connects the slide to the tailgate. A drive mechanism is provided to drive the closing side toward its raised position. The drive mechanism may be in the form of an hydraulic ram, a compression spring or a combination ram and spring.
