MAST HOISTING DEVICE Russian patent published in 2017 - IPC H01Q1/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment, particularly to the stationary one, and can be used in mast-hoisting devices (MHD) mounted on a concrete foundation, a pile or a pile-screw ones to lift the equipment to a given height having a hoist in the kit for lifting the mast with a plane-parallel turn of the upper platform and its lowering for maintenance, repair and in case of force-majeure circumstances. Assigned task is achieved due to that the mast-hoisting device comprising a base, a sectional mast with fixed on it an upper mounting platform for the antenna system according to the invention further includes a hinged parallelogram enabling at lifting the sectional mast for the upper mounting platform retain the horizontal position.

EFFECT: technical result is simplification of the MHD design while maintaining its reliability.
