ENERGY STORAGE SYSTEM WITH LIFTING SYSTEM FOR ELEVATOR Russian patent published in 2024 - IPC B66C13/28 F03G3/04 

FIELD: lifting devices.

SUBSTANCE: energy accumulation and delivery system includes an elevator, made with possibility of operation for movement of units from lower elevation to higher elevation for energy accumulation and from higher elevation to lower elevation for power generation. Winch assembly is connected with the possibility of movement with a cable, which is connected to the elevator. Winch assembly has planetary gearing assemblies, brakes, which selectively engage with at least part of planetary gearing assemblies, and drum connected to cable. Drive shaft extends between motor-generator and winch assembly. Brake is configured to operate so that the drum rotates to wind the cable for lifting the elevator to move the unit from a lower elevation to a greater elevation for energy accumulation or for operation so that the drum rotates to unwind the cable for lowering the elevator to move the unit from a higher elevation to a smaller elevation for power generation.

EFFECT: simplified control of the block lifting and lowering system.
