ROPE PRE-FAILURE WARNING INDICATOR SYSTEM AND METHOD

摘要

A pre-failure indicator system for determining a degradation or failure condition includes a rope having an elongated structural strand and a pre-failure indicator strand. The pre-failure indicator strand has a tensile strength less than a tensile strength of the structural strand. The pre-failure indicator strand constructed of a conductive wire. The pre-failure indicator strand is configured to fail when the rope is subject to tension that exceeds the tensile strength of the structural strand. An indicator generates a detectable signal when the pre-failure indicator strand fails. A transceiver detects the detectable signal. The transceiver is configured to transmit a warning upon receipt of the detectable signal.

1. A pre-failure indicator system for determining a degradation or failure condition, the pre-failure indicator system comprising:
a rope having an elongated structural strand and a pre-failure indicator strand, the pre-failure indicator strand comprised of a conductive wire and configured to fail when the rope is subject to tension that is less than the tensile strength of the structural strand; an indicator that generates a detectable signal when the pre-failure indicator strand fails; and a transceiver that detects the detectable signal, the transceiver configured to transmit a warning upon receipt of the detectable signal.
