Pendant lines are used to support the boom on draglines and electric shovels. Due to the type of work, which is highly repetitive, these pendant lines are submitted to a large number of tension/load cycles that influence service life. Traditionally the pendant lines are made of steel wire rope. Steel wire rope has a limited service life when submitted to repetitive tension-tension fatigue cycles. Oftentimes, the pendant lines are replaced too soon. Conversely frequent inspections cause unnecessary maintenance downtime. The hourly loss of revenue resulting from pendant life failure or unplanned maintenance are considerable.
