FIELD: transportation. ^ SUBSTANCE: invention proposes a device and a method to monitor the lift suspension system state and the lift cab suspension assembly unit made in compliance with the said device. The monitoring is based on measurement of an electric parameter, e.g. a suspended system resistance with ruling out the dependence upon the system temperature. The system resistance in primary state is calculated for the system monitoring temperature conditions and for those wherein the system exists in the monitoring process. The result is subtracted from the system measured cab suspension system resistance, the monitoring of which is being effected. To simplify the calculations and monitoring of the cab suspension resistance in primary state and the suspension system the monitoring of which is being effected can be converted into values of reference temperature. ^ EFFECT: higher quality of monitoring and safer lift operation. ^ 19 cl, 4 dwg |
