Steel Cord Scanning

CBM Steel Cord Scanning has been designed as a standalone system, or as an integral part of a Condition Based Monitoring System.

The primary purpose of the Steel Cord Belt Scanning system is to detect steel cord, carcass  damage and splice  irregularities, by means  of  non destructive testing during the conveyor belts' normal operation, via our remote, semi remote or field inspection services, without (depending on service) the need to stop the conveyor belt or have personnel on site.

With shrinking maintenance windows and limited downtime access, CBM has developed a system to minimize interruption while scanning all forms of steel cord conveyor belting. Steel Cord Scanning via the Magnetic Flux Leakage system is designed to detect anomalies or damage within the steel cords and splices of conveyor belting, invisible to the naked eye.

new-steel-photoWhen the system is operating, it locates areas of cord breakage, partially damaged, corroded cords, integrity of splices and health issues of the carcass. This information is available instantly with no conveyor downtime (depending upon the system combination Remote, Semi Remote or Full conveyor inspection), enabling full production to continue with limited or no interruption.

The data is captured via intelligent software on site or sent remotely via data connection to be inspected by engineers for anomalies. Damage can be identified immediately for notification and inspection.  This is achieved through data comparison against the previously captured data.


CBM Remote Operation


















CBM engineers analyse and generate comprehensive reports using this data. The opening section of the report summarises our findings and lists recommendations in order of priority, to assist effective maintenance planning.

To the left is a sample page of findings from the inspection of an event, Event 80. The event's location and type of damage are described and there is both a sketch and a photogra


ph for further reference.


Below is the cord break data for the corresponding event.











Similarly, splices are monitored. Magnetic signatures are filed and form a reference for future scans. Changes in these signatures are related to cord movement and precede splice failure.splice-evaluationsplice-signature-1






















Periodic interrogation (with a remote or semi remote installation) of the conveyor is useful in monitoring ongoing cord damage, the condition of splices (new and old) and to predict the necessity of section replacement.

Frequently Asked Questions

Q What type of belts is this system designed for?
A This CBM System is suitable for both surface and underground applications.
Q Do I need to have all my belts scanned?
A Not at all, we only implement in a way that is going to suit your company's requirements.
Q What are the key benefits?
A Detection of splice and cord damage or change, and effective maintenance & budgetary planning.
Q Who owns the data?
A You do - we keep a back up of that data and it forms part of the database for our engineers to analyse and make comparative recommendations. You will receive regular reports at a frequency that best suits your site operations.
Q Do I have to shut down the belt for the scan?
A It depends upon which of our systems you have elected to implement. With the cbmRemote and cbmSemiRemote there is no need to shut down the belt. For field inspection service, a short shutdown is required when setting and removing the equipment. The scanning occurs while the belt is operating and available for production.
