Abstract: It is demonstrated how, by combining unconventional design and revolutionary technology, the strongest cable testing machine in the world could be built at a surprisingly low cost. Technical highlights are the conception of |multiple cylinder| actuators, each equipped with three active cylinder chambers in linear array, and the application of |floating| sealing rings, able to slide within very thin-walled (|breathing|) cylinders without any metallic contact. In spite of its unorthodox conception the machine from the very beginning was remarkably easy to operate. ELS (|Experiments with Long Specimens|) was entirely conceived and built by specialists of the Swiss Federal Laboratory for Materials Testing and Research (EMPA) at Dubendorf/Zurich.
Keywords: materials testing; cable testing; testing equipment; testing machines; bridge cables; prestressing cables; mooring cables; sealing rings; thin-walled cylinders; multiple cylinder actuators.
