Hello Fellow Towertalkers.. The To lube or not to lube is akin to finding true north. some swear by a method some swear at it ! I worked at Bethlehem Steel Co after I got out of the Army.. as a crain operator, being the new guy in the dept. I was delegated to the outside crane run :(Well the duties and 90% of the lifts are identical as to height /drop and resting position. with weights up to 30,000 lb This was on a Nile 25 ton crane.the worry of the cable fatiguing being stressed at the same position IMHO would only prevail. is if the Shiver Drum dia was undersize to the bend radius of the cable . The gang that maintained these things sprayed /brushed ( hand held floor brush) on a liquid penetrating lube. My Mentor W3GM Jerry Mathis had 6 layover towers all in wet undergrowth He turned me onto a granger product I have been using on my winch cables.. and have not replaced any in 22 years at this QTH It's a cable open gear penetrating lube. it now comes in eco friendly hand pump bottle .http://www.grainger.com/Grainger/SPRAYON-Open-Gear-and-Wire-Rope-Lube-4GUM9?Pid=search Wayne W3EA
