In this test, the service life expectancy of the CF5.10.25 with cores wound in bundles in an e-chain with a 100mm radius was to be investigated.

The CF5 control cable family is available in a huge number of core/cross section combinations. Indoor cranes very often use 1.5mm and 2.5mm cross sections to supply buttons, limit switches, motors, or even simple lamps with energy. The long travels in the hall, which can be more than 80m, are demanding. The short pitch length and cores wound in bundles promote a long service life. But contamination from dust and exhaust gases also affects the cables in the area of the hall roof, where the abrasion-resistant, oil-resistant outer jacket performs well.

With a test result of over 42 million strokes with significant sagging, it could be confirmed that the cable more than meets the durability requirements in a crane application.
