Claim:
1. Apparatus for transporting a device along a tower, which comprises: at least one rail, which is extended, according to a substantially rectilinear guide direction (X), between a lower end thereof and an upper end thereof, and is provided with fixing elements by means of which said rail is susceptible of being fixed to the tower with said upper end placed at a top of said tower; at least one trolley slidably constrained to said rail, and adapted to support the device to be transported provided with at least one power cable; movement system mechanically connected to said trolley and actuatable to move said trolley to slide along said rail between a lowered position, in which said trolley is placed at the lower end of said rail, and a raised position, in which said trolley is placed at the upper end of said rail in order to arrange said device at the top of said tower; said rail comprising at least one hollow shaped profile with elongated form, which is longitudinally extended according to said substantially rectilinear guide direction (X) between a lower edge thereof and an upper edge thereof, and is provided with an external surface and an internal surface which defines a guide seat in which said trolley is slidably housed and in which the power cable of said device is susceptible to pass; wherein said trolley comprises a support bracket provided with a projecting portion to which said device is susceptible to be fixed; said projecting portion being extended outside the guide seat of said hollow shaped profile through a longitudinal slit obtained on said hollow shaped profile and being extended parallel to said substantially rectilinear guide direction (X); wherein said movement system comprises at least one pulley provided with an actuation device arranged at the lower end of said rail, with a transmission pulley fixed at the upper end of said rail, and with a drive rope supported on said transmission pulley, and provided with a first end constrained to said actuation device and with a second end fixed to said trolley; said drive rope being provided with a first section being extended parallel to said substantially rectilinear guide direction (X) between said actuation device and said transmission pulley, and with a second section being extended parallel to said substantially rectilinear guide direction (X) between said transmission pulley and said trolley; wherein the hollow shaped profile of said rail is provided with at least one first passage seat being extended in a through manner between the lower edge and the upper edge of said hollow shaped profile according to said substantially rectilinear guide direction (X), and housing therein the first section of said drive rope.
