Barrier with alarm-secured stopper grid used in highly-secure areas, has two hollow sections that form cross, and cables arranged inside respective hollow sections and following cross shape formed by two hollow sections

摘要

The barrier includes a first hollow section (1) and a second hollow section (2), in which the first hollow section has a larger cross-section than the second hollow section. The second hollow section penetrates the first hollow section, in which the first and second hollow sections form a cross (3). Cables (11,12) are respectively arranged and guided in the first and second hollow sections, in which the cables run along the longitudinal axes of the first and second hollow sections and follow the cross shape formed by the first and hollow sections.
