Dear group members,
i have encountered one problem and need to analyzed it before taking any preventive action.
Contorl cable (1/8", 7X19, steel cable) strands wires were found broken in the area where it run overs pulleys (phenolic). I have came to know that these area are critical to fatigue but couldnt figured out the reason and mechanism which led to such damage near pulleys. if some one can explain me the propbable causes / reason which can led to such occurrences or reasons which can aggravate the situation, so that i can based my maintenance procedures and frequency to avoid future recurrence.
hope for a sound engineering / scientific reply from group members.
