Title
(EN) AN ARRANGEMENT IN EXTRACTOR CRANES
(FR) AMENAGEMENT POUR LES DEPOUSSIEREURS
Abstract
(EN)
In an extraction crane (1) having an arm (2) on which to mount an extractor and other equipment, the arm (2) is hinged by means of its inner end (9) to a support (17) with the intermediary of a mounting bracket (14), so as to be allowed to pivot essentially in the horizontal plane. A retaining device (18) acts between the arm (2) and the mounting bracket (14) to retain the arm in the set pivotal position. The retaining device (18) comprises a rod (24) which carries friction washers (23) and which may be actuated by an actuator (20) via a rotationally mounted yoke (38) in order to move the friction washers (23) from their retaining frictional engagement with a plate (34) connected to the mounting bracket (14) and thereby allow the arm (2) to be pivoted as desired. The power actuator (20) is remote-controlled by a control unit positioned on the extraction hood of the extractor.
(FR)
Sur un dépoussiéreur (1) présentant un bras (2) sur lequel est monté l'appareil de dépoussiérage et des autres équipements, le bras (2) est articulé à son extrémité (9) sur un support (17) par l'intermédiaire d'une potence (14), de manière à pouvoir pivoter principalement dans un plan horizontal. Un dispositif de retenue (18) exerce son action entre le bras (2) et la potence (14), retenant ledit bras dans une position de pivotement déterminée. Le dispositif de retenue (18) se compose d'une tige (24) portant des rondelles de friction (23). Il peut être actionné par un vérin (20), par l'intermédiaire d'un arceau (38) pivotant, de telle sorte que les rondelles de friction (23) se dégagent de leur position de blocage par rapport à la platine (34) solidaire de la potence (14) et permettent ainsi le mouvement souhaité du bras (2) en pivotement. Le vérin (20) est commandé à distance par un boîtier logé sur le carénage du dépoussiéreur.
