Abstract
Translation nut for a lifting unit. Translation nut remarkable due to the combination of a sliding block (1) with a threaded tubular casing (19) on which it rests by means of a ball bearing (22), said bearing and, by support, the sliding block being selectively engaged by coupling and uncoupling means through an intermediary coaxial piece moving axially in movements of coupling and uncoupling under the effect of said coupling and uncoupling means. This invention is of value to manufacturers and assemblers of truck bodies.
