(54) Title (EN): JACK SYSTEM
(54) Title (FR): SYSTÈME DE VÉRIN

(57) Abstract:
(EN): The present jack apparatus is particularly adapted for heavy duty lifting. The jack apparatus includes a base; a pair of screw jacks; a yoke supported by the screw jacks; a lifting tube supported on the yoke; a shaft coupler coupling the screw jacks; a power unit driving one of the screw jacks and through the shaft coupler also driving the other screw jack; and a housing covering the screw jacks and other components. The pair of screw jacks each have threaded lifting shafts designed to eliminate risk of unexpected lowering of the jack's lifting tube even if power is lost. A jack system is described including two or more of the jack apparatus controlled by a single control for simultaneous operation.
(FR): La présente invention concerne un appareil de vérin, lequel appareil est particulièrement apte à un levage de forte puissance. L'appareil de vérin comprend une base ; une paire de vérins à vis ; une culasse supportée par les vérins à vis ; un tube de levage supporté sur la culasse ; un coupleur d'arbres couplant les vérins à vis ; un vérin de commande entraînant l'un des vérins à vis, et entraînant également, par l'intermédiaire du coupleur d'arbres, l'autre vérin à vis ; et un boîtier recouvrant les vérins à vis et d'autres composants. La paire de vérins à vis présentent chacun des arbres de levage filetés conçus pour éliminer le risque d'abaissement imprévu du tube de levage du vérin, même si de l'énergie est perdue. L'invention concerne également un système de vérin comprenant deux ou plusieurs des appareils de vérins commandés par une commande unique pour un fonctionnement simultané.
