Groove depth, fleet angle and back to back bends all coupled with hard accelerations and decelerations (the latter thanks to the consultant FTF spec) add to shortened rope life. I inherited two three and a half year old basement machines, Holister Whitney with the simple single deflector over the driver and four more bends in the o.h. which shredded all five ropes on two cars within a month of each other. we're learnin' alot about torsional stresses, back to back bends and the advantages of Langs Lay rope versus Regular Lay rope in certain applications. Expensive year so far.
