Testing acc. to EN50119 Product Tests (mechanical and electric testing of complete hangers) Catenary components will be exposed to higher and higher requests. Particularly rising speeds and the long durability requested put new challenges to technique. "New components", that shall be released for installation in catenary systems, must be tested objectively, comparably and in a realistic way corresponding to the actual impacts and according to mandatory regulations. (fig. 1 - KRUCH development: short-gliding-hanger - approval process) "Old components", that are already in use for several years, are to be tested for their suitability for new, increased requests. (for ex. - Dutch gliding hanger - in use for >20 years) Technical Specifications KRUCH took notice of the market requirement for hanger testing and achieved an appropriate development and investment in testing facilities and constructed partnerships. By this KRUCH is able to test hanger systems at most versatile stressings: Lifespan tests simulation of trains (pantographs) passing through (e.g. 2,000,000 times) hanger lengths: 0-1000mm variable adjustable vertical and sloping adjustability frequency: 0-2 hertz, variable adjustable raising / compression: up to 200mm weight load: adjustable Tensile loading tests to maximum 5700N extracting hanger clamp of the contact wire extracting hanger clamp of catenary cable extract the hanger wire of the clamp Electrical tests short circuit test (e.g. 5kA for 500ms) long-term current test (e.g. 100A / 20min) isolation failure References In both cases the product risk must be minimized for the regulating administrative authority! National and international standards give the arbitrative defaults for appropriate product tests.
