SYSTEM OF DRIVE TO BE ARRANGED IN SMALL ROOMS Russian patent published in 2007 - IPC B66B11/00 

FIELD: mechanical engineering; drives with compact motors.

SUBSTANCE: proposed system contains compact drive motor, driving sheave of smaller diameter with double winding through countersheave and wire rope suspension of cabin. Drive together with countersheave and fasteners of end of wire rope/and additional guide rollers at side of cabin and counterweight are mounted on common frame of base. Frame of base is installed on ceiling of room accommodating drive mechanism with use of without use of flexible gaskets and without fastening on room ceiling for drive mechanism. Driving sheave and countersheave are arranged at such a distance relative to each other that descending runs of wire rope correspond to center-to-center distance between cabin and counterweight developed for said system. Module of system is divided through frame into part with driving machine and countersheave and part with fasteners of ends of wire rope or/and additional guide rollers. Counterweight is directed between rear wall of well and rear wall of cabin or between side wall of well and side wall of cabin depending on accessibility of cabin.

EFFECT: simplified design of drive, increased service life.
