Heavy Lifting Permanent Installation System Custom Example of Permanent Industrial Equipment Example of Permanent Elevator Installation Elevator Market

AMC AMC was born in 2007, as a start-up of the Polytechnic of Turin. We started producing ropeway devices, that requires MRT inspection and an EN12927compliant design. Our first challenge was the test to achieve the accuracy and the stability required by the ropeway market. After several phases of trials and errors, our equipment successfully passed the test with a signal-to-noise ratio bigger than 2. In the following years, AMC made its entrance in the Heavy Lifting and Elevators Market with standard and customized solutions. Thanks to our experience and knowledge, we became an examination...

The MRT method is a non destructive, magnetic and contactless procedure that allows to detect broken wires, distortions and corrosion on steel wire ropes. This magnetic method was introduced in the cableways sector to inspect the haulage and carriage and to identify external and internal defects. In the 80s this technique broadened the offshore heavy lifting market due to the increasing needs in terms of efficiency and safety. Most recent version of ISO4309 includes MRT as assessment method for the inspection of generic heavy lifting wire ropes. AMC introduced a lot of innovative concepts...

If the rope is magnetically saturated, when a local flaw appears, a part of the magnetic flux lines move from the inner part of the rope to the surrounding air. The quantity of this flux and its path depend on the characteristics of the damage. Inside the device, some probes acquire the flux distortions and traduce them in a measurable quantity (i.e. voltage or current). A diagram in the user-interface will then show the effects of the flaw. Each peak in the graph corresponds to one or more broken wires in the inspected wire rope. The LF signal is fully regulated by the EN12927 standard,...

Training A perfect MRT inspection is the combination of good acquisition and good interpretation. The user must know how the equipment works and look for all the causes that could affect its performance. For this reason, the signal interpretation is fundamental in order to define the rope status. A fully automatic interpretation is rarely possible, especially for mobile application. Thanks to our training, our customers will complete the journey to become MRT experts. Two different trainings and constant practice are the most important steps of this process.

3. Training A. Operative training: it teaches the correct use of the inspection system and the interpretation of the signal. The inspector will be guided through a 6 steps training. Each step will last approximately 1-2 hours. All the step can be done online. If it is possible, we suggest doing the technical-practical part on-field. After at least 6 months of practice, the inspector can attend the ISO9712 course.

3. Training B. II level training (ISO 9712): it is a strong technical course that allows the customer to work in full compliance of ISO9712 norm. C OU RS E G E N E R AL C HAR ACTE RISTI C S The ISO 9712 course (on-field) lasts 3 days, 8 hours per day.

Sectors MRT devices apply in all wire ropes sectors, which are: These areas use wire ropes in different ways, but the general aspects about safety and service continuity are very similar. Cableways carry people from one place to another and the condition of wire ropes is really important to avoid accidents. This applies also for elevators and heavy lifting, in which a failure of the rope could cause huge issues in terms of responsibility, human life and finance. Cableways Heavy Lifting → S E E P. 10

Heavy Lifting MRT made its first appearance in this sector in the '80s, especially for some specific applications. Although heavy lifting ropes don’t lift humans but loads, safety is really important because a failure can cause a disaster (imagine a steel mill, or a mine). A strong progress in technology in the early 2000 led to the availability of heavy lifting devices, compliant with cableways standards, in order to improve the final user experience and simplify the use of MRT systems in this environment. The updated version of ISO4309 (2017) indicates MRT as stateof-the-art method for...
