Patent attributes
The invention provides a mast comprising a modular, hollow tubular body having cylindrical, outer wall segments with an outer surface and enclosing an axially extending cavity, said tubular body comprising in its cavity a first mast segment arranged in between a base segment and a second mast segment and releasably connected thereto. Each of the base, first and second mast segment has an internal structure for bearing the weight of the mast, the internal structure of the first mast segment comprises in the cavity an axially extending inner cylinder connected via radially extending ribs to outer cylinder portions at a first respectively a second end of the inner cylinder and said ribs axially extending from said first end to said second end. Said inner structure being surrounded by a removably mounted, outer wall segment. The inner cylinder by a core wall of the inner cylinder encloses an axially extending core cavity for enabling cabling to pass through from the cavity in the base segment to the cavity in the second mast segment. In mounted position the first part is connected with the first end of its core wall directly to the base part and with a second end of its core wall to the second mast segment.
