Abstract

L'invention se rapporte à un mécanisme de déplacement pas à pas le long d'une tige, de préférence verticale. L'invention se particularise par un vérin à double effet à tige intérieure creuse coaxiale à la tige de déplacement, le corps du vérin étant monté solidaire d'un dispositif de blocage sur la tige de déplacement présentant un dispositif analogue solidaire de la tige du piston pour un mouvement d'avance pas à pas avec un verrouillage temporaire à chaque avance. Application: remplacement de vérins à grande portée, levage et mise en position de charges et d'outils.
