HOISTING-AND-REMOVAL DEVICE FOR TELESCOPIC MAST Russian patent published in 2020 - IPC H01Q1/12 

FIELD: antenna equipment.

SUBSTANCE: lifting-and-extending device is intended for use in mobile antenna installations. Device comprises a base with a vertical axis, on which a cantilever beam, a yoke with possibility of rotation in a vertical plane, pivotally articulated rods, and a bracket is installed with a possibility of fixation in the transport and working position. Device is equipped with a flange, a turning mechanism and a lifting mechanism with a support. Mechanism of rotation is connected to the bracket and through the flange to the cantilever beam, the free end of one of the tie-rods is attached to the flange, and the free end of the other tie-rod is rigidly connected to the base. Lifting mechanism is equipped with actuator with reduction gear, actuator rod is connected with yoke for reciprocation of yoke. Actuator is connected to the bracket by means of a turnbuckle and rigidly connected to the support, in which the guides connected to the yoke are installed with possibility of movement.

EFFECT: higher carrying capacity of the device, improved operational capabilities of the device by providing an electromechanical turn of the mast from horizontal to vertical position, as well as electromechanical lifting or installation of the mast on the ground in the working position.
