The whole construction of the invention allows the embodiment of three-type antenna rising systems (manual, mechanical and electric rising system). Said construction is composed of the motor arrangement 3,4 comprising the respective rings 6,7, the hexagonal pistons 9, 11 initiated by the motor (mechanical rising system), and the box 3,4 with oil compressed by the press pedal 3 (pneumatic rising system). The gravity centre of the rising system is directed to the base 1 and thereafter conveyed inparts to the points 2,3,4,5,6,7,8,9,10,11, 12; correspondingly, all rising energy is vertically directed and the construction well fixed on the ground or the subsoil in order that weather problems and endogen influences such as seismic vibrations can be faced. The simple practical antenna rising construction is composed of the base 1 and a wire rope reel rotating at the points 2,3,4,5,6,7,8 (manual rising system). |
