(FR) ACTIONNEUR
Abstract: front page image
(EN)An actuator (10) for use in installing or extracting piles and the like has a common member (12) supported at (14) and having jaws (16) for gripping a pile. Within the block (12) a double-acting piston (18) is located alongside a space (20) for a control valve arrangement which provides hydraulic fluid, in various ways described, to create vibratory or impact forces from the piston (18). The piston and the valve arrangements are both removable and replaceable by alternatives, to modify the mode of operation of the actuator (10).
(FR)Cet actionneur (10), conçu pour l'installation ou le retrait de pieux et d'éléments analogues, comporte un élément commun (12) fixé au point (14) et possédant des mâchoires (16) pour saisir le pieu. Au sein de l'élément bloc (12), un piston à double-action (18) est situé le long d'une cavité (20) logeant un système de valve de commande qui fournit un fluide hydraulique, de diverses façons, afin de créer des forces d'impact ou des forces vibratoires à partir du piston (18). Le piston et le système de valve sont amovibles et remplaçables par d'autres, ce afin de modifier le mode d'opération de l'actionneur (10).
