A lifting device (1) for goods containers (35) includes a body member (2). Four inner pickup elements (7, 8, 9, 10) are movably mounted on the body member (2). Two first extendable members (3, 4) are movably mounted on the body member (2) for movement between a first position in which the first extendable members (3, 4) are not extended from the body member (2) and a second position in which the first extendable members (3, 4) extend from opposite ends of the body member (2). Two second extendable members (5, 6) are provided with one second extendable member (5, 6) being mounted on each of the first extendable members (3, 4). Each second extendable member (5, 6) is movably mounted on the respective first extendable member (3, 4) for movement between a first position in which the second extendable member (5, 6) is not extended from the first extendable member (3, 4) and a second position in which the second extendable member (5, 6) is extended from the first extendable member (3, 4). Each second extendable member (5, 6) has two outer pickup elements (17, 18, 19, 20) mounted adjacent the end furthest from the body member (2) when the second extendable member (5, 6) is in the second position. In addition, two of the inner pickup elements (7, 9) are fixedly coupled to one of the first extendable members (3) for movement therewith and the other two inner pickup elements (8, 10) are fixedly coupled to the other of the first extendable members (4).

La présente invention concerne un dispositif (1) de levage destiné à des conteneurs (35) de marchandises qui comprend un corps (2). Quatre éléments (7, 8, 9, 10) intérieurs de ramassage sont montés mobiles sur ce corps (2). Deux premiers éléments extensibles (3, 4) sont montés mobiles sur ce corps (2) permettant un déplacement entre une première position dans laquelle ces premiers éléments (3, 4) extensible ne sont pas dépliés à partir du corps (2) et une deuxième position dans laquelle ces premiers éléments (3, 4) se prolongent à partir des extrémités opposées de ce corps (2). Deux seconds éléments (5, 6) extensibles sont prévus avec un second élément (5, 6) extensible monté sur chacun des premiers éléments (3, 4) extensibles. Chaque second élément (5, 6) est monté mobile sur le premier élément (3, 4) respectif de façon à permettre un déplacement entre une première position dans laquelle le second élément (5, 6) extensible n'est pas déplié à partir du premier élément (3, 4) et une seconde position dans laquelle le second élément (5, 6) est déplié à partir du premier élément (3, 4) extensible. Chaque second élément (5, 6) extensible possède deux éléments (17, 18, 19,20) de ramassage montés près de l'extrémité la plus proche du corps (2) lorsque le second élément (5, 6) extensible est dans la seconde position. Deux des éléments (7, 9) intérieurs de ramassage sont, en outre, couplés de façon fixe à l'un des premiers éléments (3) extensibles de façon à permettre un déplacement avec celui-ci et les deux autres éléments (8, 10) intérieurs de ramassage sont couplés de façon fixe à l'autre des premiers éléments (4) extensibles.
