TELESCOPIC MAST (EMBODIMENTS) Russian patent published in 2019 - IPC H01Q1/10 

FIELD: physics.

SUBSTANCE: invention relates to antenna engineering and can be used in telescopic masts attached to chassis or car body or installed independently and designed to lift payload, for example, antenna devices, video surveillance equipment, lighting, etc., to a given height. Telescopic mast comprises sections including fixed section 1, movable sections 2, 3, 4, 5, as well as system of blocks consisting of blocks 6 of upper part and blocks 7 of lower part, rope 8, winch 9, tensioning device 10 comprising bracket 11 with roller 12 arranged therein, first resilient element 13, cup 14, second resilient element 15, drive 16 including threaded part 17 and carriage with system of units 18. Units 6, 7 of upper and lower parts of fixed section 1 and every movable section 2, 3, 4, 5 are located opposite each other and together with units 7 of tension device 10 form mechanism of tackle. Tensioning device is arranged in upper movable section 5.

EFFECT: technical result is higher lifting capacity of mast, as well as increased efficiency of post-lining system of mast and increased resistance to skews and jamming during movement of mast sections during its deployment and coagulation.
