Title
(EN) LIFTING ASSEMBLY
(FR) ENSEMBLE DE LEVAGE
Abstract
(EN)
A lifting assembly (1) for gripping and lifting an object (2) comprising, a primary component (3), a secondary component (5) connected to an moveable away from the primary component to an engagement configuration in which it grips the object and moveable towards the primary component to a disengagement configuration in which it releases the object, a plurality of arms (21) pivotally mounted (22) on the primary component and depending therefrom, splay means (30, 31, 32) provided on the secondary component adapted to splay the arms with respect to each other when the secondary component is in the disengagement configuration, and de-coupling means (17) attached to the secondary component the de-coupling means being adapted to move the secondary component to the disengagement configuration, wherein the construction is such that when the lifting assembly is lifted in the absence of activation of the de-coupling means, the lifting assembly assumes the engagement configuration through the primary component moving away from the secondary component thereby causing the arms to pivot inwardly so that they grip the object.
(FR)
La présente invention concerne un ensemble de levage (1) pour préhender et soulever un objet (2) comprenant un composant principal (3), un composant secondaire (5) relié de façon à pouvoir s’écarter du composant principal dans une configuration d’engagement dans laquelle il préhende l’objet et à se rapprocher du composant principal dans une configuration de relâchement dans laquelle il relâche l’objet, une pluralité de bras (21) montés de façon pivotante (22) sur le composant principal et dépendant de lui, des moyens d’écartement (30, 31, 32) prévus sur le composant secondaire et adaptés pour écarter les bras les uns par rapport aux autres lorsque le composant secondaire est dans la configuration de relâchement et des moyens de découplage (17) fixés au composant secondaire, les moyens de découplage étant adaptés pour amener le composant secondaire dans la configuration de relâchement, la construction de l’ensemble de levage étant telle que lorsqu’il est soulevé sans activation des moyens de découplage, l’ensemble de levage prend la configuration d’engagement par l’intermédiaire du composant principal s’écartant du composant secondaire, amenant ainsi les bras à pivoter vers l’intérieur de manière à préhender l’objet.
