Industrial endoscopic inspection

Endoscopy: the solution to explore inaccessible areas of your equipment

Endoscopy is used to visualize the inside of a cavity to obtain accurate images of areas the human eye in unable to access. The images produced, in the form of photos, enable an accurate analysis of the areas inspected.

We work quickly in all areas of industrial endoscopic inspection and the video examination of pipe networks. We bring a professional, rigorous approach to many business sectors, including aeronautics, industry, consulting, real estate and construction, climate engineering, sanitation and roads, and safety. All our interventions are accompanied by a photo in order to display and monitor the evolution over time of all the defects observed. Each report is customized according the needs of the specific customer.

Need / Context

CEE R SCHISLER is one of the leading European manufacturers of paper bags and cardboard cups. It supplies fast food chains and the biggest retailers, meaning that it must avoid all production stoppages. Its ageing equipment is a primary concern.


To respond to this maintenance issue, we offer vibration analysis of our customer’s workshops consisting of extruders, reels, printers, cutters, etc. We inspect the 90 main motors (from 15 to 250 KW), flagging up those products in need of maintenance operations. Convinced by the results of our first campaign, CEE R. SCHISLER went on to offer us a 3-year contract.
