Forensic Failure Analysis

For conveyor forensic failure analysis field service, CDI uses a variety of instruments, including many of our own design, and a DAQ system and software of our own devising, to measure a variety of performance parameters during conveyor start-up, steady state running and shut-down, including

  • Belt speed.
  • Applied torques.
  • Take-up position.
  • Belt side travel.
  • Brake response time.

CDI also uses BELTSTAT and BELTFLEX as forensic failure analysis tools to simulate conveyors proposed by others, to audit their design, or on existing conveyor systems in order to duplicate and troubleshoot operational problems. This type of analysis can substantially reduce the amount of downtime involved in identifying and replacing a poorly designed or badly maintained component.

The data collected on the conveyor’s performance is analyzed, and the behavior simulated using BELTFLEX. Based on our measurements and simulations, CDI will recommend changes in the conveyor control systems, or will recommend the replacement of faulty, or poorly designed components.

The graphs below show a case study in which CDI’s forensic analysis of the conveyor system eliminated drive control instabilities that were causing excessive system downtime due to accelerated wear and tear on the belt, the drives and the take-up system of this particular conveyor.
