DEVICE FOR ELEVATOR SUSPENSION AND/OR ACTUATION Russian patent published in 2016 - IPC B66B7/06 

FIELD: transport.

SUBSTANCE: elevator system comprises the cabin, one or several pulleys and one or several belts coupled with the cabin to interact with one or several pulleys for suspension and/or actuation of elevator cabin. One or several belts include wires integrated in one or several strands and sheath which, in fact, retains at least one or several strands. In compliance with the first version of the system and the belt production process, the D/d_c radio for a strand between the minimum diameter D of one pulley or several pullets interacting with the belt and the maximum diameter d_c of one or several stands is smaller than 55. The D/d_w ratio for the wire between the pulley minimum diameter D and the wire maximum diameter d_w varied from approx 160 to approx. 315. The belt ratio between the strand maximum diameter and the wire maximum diameter makes approx. 4-7.65. Every strand includes approx 49 wires while wire diameter makes approx. 0.68 mm.

EFFECT: lower production costs.
