ELEVATOR Russian patent published in 2020 - IPC B66B1/24 B66B9/00 B66B11/08 

FIELD: machine building.

SUBSTANCE: invention relates to lifting machines, particularly, to elevators. Lift comprises cabin (2) arranged to move in elevator shaft between landing floors. To the roof of the cabin by its end the upper part of the rope is attached, which passes through the lifting mechanism, which is rigidly fixed in the upper part of the shaft, after the lifting mechanism, the upper part of the rope is rigidly attached to the upper part of counterweight (7). When cabin (2) is lowered, counterweight (7) together with set of permanent magnets (16) rises upwards and its magnetic field crosses coils of electric winding (12), inducing an electromotive force in them, as a result, in the circuit consisting of electrical winding (12) and electric accumulator (15), electric current starts to flow, charging electric accumulator (15). When cabin (2) is lifted, control device (14) is actuated to disconnect electric circuit consisting of electric winding (12) and electric accumulator (15). As a result, electromechanical force preventing cabin lifting (2) is not created.

EFFECT: technical result consists in expansion of functional capabilities of device due to generation of electric energy.
