MAST WITH DIRECTION STABILIZED UPPER WORKING PLATFORM Russian patent published in 2018 - IPC E04H12/00 

FIELD: construction.

SUBSTANCE: invention relates to high-rise facilities for the placement of technical means requiring, for its normal operation, installation with a certain directivity, namely for: antennas with a narrow beam pattern; aerial optical communication devices; optical surveillance devices of the visible and infrared ranges cameras type used for the protection of various objects and the state border, inclusive. Said technical result is achieved by fact, that the mast with the direction stabilized upper working platform, including the upper working platform, vertical posts, articulated to the vertical posts horizontal struts, and side extensions connected to the base, consists of two pairs of vertical posts. At that, the each pair both posts are pivotally connected by identical horizontal struts. Vertical posts pairs are connected to each other either by pivotally fixed pairs of identical additional horizontal struts, or by platforms articulated onto the vertical posts pairs horizontal struts. At that, the topmost mast platform is the working platform.

EFFECT: technical result of the invention consists in a significant increase in the mast upper platform position angular stability under any permissible in a given location wind loads and other negative natural factors, with simultaneous significant reduction in the structure metal consumption and simplification of its assembly on site.
