Title:
DEVICE FOR THE CONTINUOUS, PERMANENT MONITORING OF STEEL CABLES USED IN INSTALLATIONS FOR THE TRANSPORT OR LIFTING OF PEOPLE AND MATERIALS
Document Type and Number:
WIPO Patent Application WO2007012685
Kind Code:
B1
Abstract:
The invention relates to a device for the continuous, permanent monitoring of steel cables used in installations for the transport or lifting of people and materials. The invention consists of an inductive magnetic head comprising an assembly of permanent magnets (1) which are disposed such as to generate a magnetic field flux (2) through the steel cable (4) to be monitored. Flux variations caused by cable defects are detected by the different inductive sections (5). The position of the cable defects can be ascertained without the use of physical contact mechanisms, but instead by comparing the signals from the two sensor elements having identical characteristics. A software program is used to interpret the signals obtained from the device, such as to equip the operator with a tool that enables the cable to be permanently monitored.
