Abstract

A cable test bench for testing a test cable to establish service life, replacement age, number of flex cycles, and/or winding behavior, has a deflection system including at least one deflector roll to deflect the test cable, one test cable drive to wind and unwind the test cable via the deflection system, and one test load to load the test cable. The cable test stand has an additional cable test drive for winding and unwinding a safety cable and/or the named test cable, and a control device for controlling the additional cable drive and/or the test cable drive in a manner wherein the two are adjusted to each other, in such a manner that the load of the test cable can be adjusted differently for different test cable segments and/or different winding directions and/or different winding cycles and/or different phases of a winding cycle.
