The present invention relates to an
assembly (20) for lifting a load element (11, 12, 1A, 1B, 15) from a base region of a construction (1), in particular a
tower of a wind
turbine, to another region of the construction (1), and / or for lowering the load element (11, 12, 1A, 1B, 15) from said other region of the construction (1) to the base region of the construction (1), the
assembly comprising: a platform element (20A) for supporting the load element (11, 12, A, 1B, 15); lifting means for lifting the platform element (20A) from the base region of the construction (1) to said other region of the construction (1) and / or for lowering the platform element (20A) from said other region of the 10 construction (1) to the base region of the construction (1); and a shifting element (27) arranged to be able to change its position with respect to the platform element (20A) in order to move the load element (11, 12, 1A, 1B, 15) in said other region of the construction (1) from a load lifting position on the platform element (20A) to a load installation position on the construction (1), wherein the lifting means are supported by an anchoring
assembly (2) able to be secured in the top region of the construction (1) and in that, in the load installation position, the platform element (20A) is disposed at least partly below the top of the construction (1). At the same time, the present invention also relates to a corresponding lifting and / or lowering method.
