Winspect performs automated visual inspection of your ropes

Why is visual rope inspection necessary ?
  • to ensure the safety of ropeway installations
  • to identifiy rope anomalies and to prevent their extension
  • to schedule repair actions at the right time
  • to optimize rope operation and to minimize the consequences of maintenance issues
For which result ?
  • to identify external damage 
    • external wire breaksruptures de fils extérieurs
    • structural modification like strand sliding, loosen wire, twisting, waviness
    • wear, corrosion and other external mechanical failures
  • to assess the severity of rope damage and the impact on future rope operation
  • to trigger prevention actions 

Winspect technology brings an efficient and practical solution to the difficult issue of visual inspection as required by authorities. Winspect which makes visual inspection reliable, enables to inspect 100% of the external surface of rope, with no retina visual uncertainty with the help of an image processing software aimed to identify the location of rope surface anomalies. Winspect moreover allows to monitor the spatial distribution of rope diameter and lay of length thus preventing abnormal operation of inspected ropes.

How does Winspect work ?

Winspect device embeds a belt of LEDs that uniformly enlighten the external surface of rope. Images of the external surface are constinuously captured by means of 4 cameras covering a complete rope scan and simultaneously recorded with a dedicated acquisition system. In situ test require no more that 6 minutes per kilometer for an operating speed of 3 m/s.

Winspect analysis

A dedicated iRopeEvaluation software automatically scans the complete surface of inspected rope and yields a list of superficial anomalies. Image processing algorithms are an innovation developed jointly by Winspect Gmbh and its partner the IFT institute from the University of Stuttgart. Winspect technology moreover permits to extract important information such as the diameter and lay length of the rope as drawn on figures above.
The iRopeEvaluation software allows to save snapshots of identified failures and to edit an inspection report that sticks to the criteria of EN-12927 standard and other regulations. Following instances exhibit two anomalies typically encountered such as an external wire break or a lightning stroke.

Key points

Reliability and simplicity

- makes visual inspection reliable complementary to magneto-inductive testing (MRT)
- 100% of rope surface is captured by cameras
- Anomalies are identified by supervised image processing algorithms

Optimization and sustainable maintenance
Stakes and customer needs


Letscan is the sale distributor in France of Winspect technology developped by Winspect Gmbh and assists customers in
  • developping their rope maintenance strategy
  • installing Winspect technology
