When is it necessary to perform the alternate flexion test?

 THE ALTERNATE FLEXION TEST This test is performed on cables subjected to frequent flexions, such as service lift cables. The objective of this flexion test is to demonstrate that both the construction of the cable and materials utilized in its manufacture are the most suitable to guarantee its durability. In certain applications, cables are subjected to […]
