AMC Instruments designs, manufactures and sells systems for the detection of defects within ropes and metal manufactures. AMC has made an ad- hoc tool for the ropes adopted in the lifting of loads, cableway and people. The equipment helps the people involved in the maintenance or verification of ropes with a simple, quick and efficient of the ropes, highlighting internal and external broken wires or cross section reduction (e.g. corrosion or abrasion) The system is composed by a detector connected to an acquisition unit that allows to visualize real time signal and store the data in order to create a test report. The operating principle is based on the method called magneto-inductive which today is used for non-destructive testing of wire ropes of lifting equipment of people as cableway, chairlift, etc.
