Abstract

Cet appareil comporte un vérin disposé verticalement et muni de moyens de fixation à un organe dont le déplacement relatif est à compenser par exemple le crochet de levage 19 d'une grue. Une pompe réversible 105 d'alimentation et un moteur de commande de la pompe sont supportés par le cylindre du vérin. Un détecteur de déplacement vertical 110 est monté sur l'organe mobile constitué par une barge 16, et engendre un signal qui commande ralimentation du vérin et provoque le déplacement de la tige 26 du piston de ce vérin qui sort ou rentre en fonction du déplacement détecté.This apparatus comprises a jack arranged vertically and provided with means for fixing to a member whose relative displacement is to be compensated for, for example, by the lifting hook 19 of a crane. A reversible feed pump 105 and a pump control motor are supported by the cylinder of the jack. A vertical displacement detector 110 is mounted on the movable member constituted by a barge 16, and generates a signal which controls the re-feeding of the jack and causes the displacement of the rod 26 of the piston of this jack which extends or retracts according to the displacement detected. .
