FIELD: electricity.
SUBSTANCE: method of regeneration of elevator motion current with use of a DC generator when lowering cargo, a DC motor - when lifting cargo and an intermediate electric power accumulator. Mechanical connection between cable pulley, generator and motor is ensured by an open single-stage gear between the rim fixed at the end of the cable pulley, and gears fixed on shafts of the generator and motor.
EFFECT: invention is aimed at improving energy efficiency of lift installation irrespective of elevator winch design.
