The invention relates to a rope test stand for testing a test rope as to its service life, discard criteria, acceptable number of reverse bending cycles, and/or winding behavior. Said test stand includes a deflection system that comprises at least one deflection sheave for deflecting the test rope, a test rope drive for winding and unwinding the test rope via the deflection system, and a test load for loading the test rope. According to the invention, the rope test stand comprises an additional rope drive for winding and unwinding a safety rope and/or the aforementioned test rope, and a control device for controlling the additional rope drive and/or the test rope drive in a coordinated manner such that the load on the test rope can be differently adjusted for different test rope sections and/or different winding directions and/or different winding cycles and/or different phases of a winding cycle. This allows the load applied to the test rope to be varied by additionally connecting the additional drive to a greater or lesser extent or increasing or reducing the force applied to the rope by the additionally connected additional rope drive without modifying the test load, thus dispensing with the need to rearrange the rope test stand, e.g. replace the test load. |
