FIELD: transport.
SUBSTANCE: invention relates to elevator installations control. The monitoring system (24) includes supporting wire belt, the first group of resistors (40a-h) and the second group of resistors (42) or pulse-width modulators to produce reference voltage, output nodal points (44a-g), sequence of comparators (46), light-emitting diodes (48). Each of the comparators (46) is made capable to compare voltage on at least one resistor of the resistors (40a-h, 42) with reference voltage and to produce output signal corresponding to specified comparison. Elevator installation belt is controlled for coating layer wear. Effective value of wire belt resistance can indicate actual resistance showed by supporting structure.
EFFECT: elevator supporting wire belt monitoring.
