Zusammenfassung:	A lifting device is provided which can obviate the need for a permanently installed large hoist. The lifting device (12) is used to lift and lower a submerged pump (2), which is used for transferring a liquified gas, inside of a pump column (3). The lifting device (12) is provided with a cable (13) and a hoist (14) connected to the cable (13). The cable (13) is provided with multiple split cables (13B), and multiple connecting links (16) which detachably connect the multiple split cables (13B). L'invention concerne un dispositif de levage qui peut éviter le besoin d'un grand treuil installé de façon permanente. Le dispositif de levage (12) est utilisé pour relever et abaisser une pompe immergée (2) qui est utilisée pour transférer un gaz liquéfié, à l'intérieur d'une colonne de pompe (3). Le dispositif de levage (12) est pourvu d'un câble (13) et d'un treuil (14) relié au câble (13). Le câble (13) est pourvu de multiples câbles divisés (13B), et de multiples liaisons de raccordement (16) qui relient de manière détachable les multiples câbles divisés (13B).
