Wire Ropes Magnetic – Inductive Inspection

Wire Ropes Magneto-Inductive Inspection Method

Swiss Approval Advanced NDT Laboratory, offers Wire Ropes inspection and Certification services, for Rope-Ways & Industrial Lifting & People Lifting equipment.

This specific Laboratory activities are based in Greece, and an significant number of qualified inspectors, offering inspection services in lifting equipment, are in place.

Our advanced System, is usually able to perform tests on wire ropes up to 20mm in diameter, and from 20mm up to 40 mm in diameter.

For larger Diameters for Naval and Offshore Sector, we can also offer inspection services with additional tools, specifically designed for wire rope diameters from 40 to 80mm or higher.

The ordinary System, the so called Detector, with Weight approx. of 17.5 kg, allows the measurement of the LF Signal (Localized Fault), which is an objective identification of broken wires (internal and/or external). The main characteristics of the services delivered through our devices are:

  • Digitally acquired LF Signal
  • Extreme lightness (due to the FEM optimization of the magnetic structure) able to be used in mobile configuration;
  • Rope Centering System (wheel mechanical guiding system) that allows big improvements both in signal quality than in friction reduction in the internal device bushings;
  • Presence of an Encoder system for defect localisation

The Data ACQUISITION SYSTEM, coupled with the Detector, consists of:

  • Personal computer;
  • Acquisition board;
  • Dedicated Software (ROPE L&R Monitor 1.11) for real time monitoring, storing, post-processing and reporting of the LF signals.

The ROPE device allows a safe, reliable and objective control of the rope integrity, by highlighting the presence of internal and external broken wires, wear and corrosion, in according to the UNI ISO 4309 standard.

The devices are certified in according to the EN 12927-8 regulation.
The detector with Max speed: 8 m/s, is wired connected to a record unit, that allows to acquire, show and store the data in order to give to the operator a complete management of the signals.

Calibration Blocks

Swiss Approval Advanced NDT Laboratory Staff, is working consistently to guaranty the maximum efficiency and reliability of our Testing Results.

Specific Calibration Blocks for each method and different materials, related to different International Standards, are designed and developed within our Laboratory, in order to build in house our Know-How, necessary for service delivery of excellence.

Development of inspection capacity for this category of materials, usually includes many, if not all, of the following:

  • Modelling,
  • Simulation,
  • Fabrication of mock-ups and samples containing realistic defects,
  • Procedure development,
  • Validation and subsequent training.

Such development of inspection resources and capacity represents for Swiss Approval Top Management, substantial commitments of time, high qualified personnel and significant capital investment.

Accreditation ISO 17025

Swiss Approval Advanced Laboratory based in Europe, is currently under ISO 17025 accreditation process.
