Abstract
A jack configuration, which may be characterized as a half scissor jack, which achieves the objects of simplifying manufacture by reducing component parts and limiting overall size of the jack while providing the requisite load bearing and height variation characteristics appropriate to the intended vehicle lifting and which furthermore reduces the potential for a torsional deflection in the base channel. Torsional deflection is reduced by creating a box section in the base channel, preferably by providing a channel bracket structure that spans the base channel to maintain the spacing of the side walls of that component.
