replacing cable on my crane

I used anti rotation wire rope, as most of my work is single part line. Don't know about the pre formed thing, all I know is it laid out flat (when off the reel) with no twisting, and the pickup method and light braking winds it up real pretty, reeling off the spool would present some practical considerations as to maintaining some tension, I guess a real good pair of gloves and a hell of a grip might do it, I'll stay with the truck. This (the cable type)was on the advice of the outfit that does my crane inspections, and has been around for quite a while with a good rep. I was actually doing a job for them (removing bridge crane components for repair in a industrial building) and he commented on the "windup" of the wire rope that was then on my crane, he asked me how often I go single line and and how often I need multi line/load block operation for bigger loads and he stated that AR was the way to go. I forget the exact type, I just let him get it for me.... about 500 bucks for 325' of 9/16" as I recall.
I like it fine, no wind up of the headache ball when single part, and it works for when I go up to a 3 part line (my max needed). I commented to my buddy that I had borrowed the 26 ton Altec from that he ought to look into it, as even picking a 1,000 lb load really spun up his ball, his response was out at the Site (a large government nuke research facility, lots of crane work there and many gov regs) they would not allow a crane operating there with AR cable. Go figure.... I know from airplane work, wire rope technology is a deep subject, and I remember one type of ultralight years ago that suffered a few control cable failures, quickly traced to using the wrong weave combined with the wrong pulley dia, thus quickly fatiguing the cable,luckily crane use wire rope is a mature science by now I'd imangine. Commuters on the Bay Bridge are finding out the importance of wire rope, as the bridge had to close last week after "a cable snapped"!
Vietnam??? Take an ad out in the local Penny Saver/Thrifty Nickel, in the farm section, it'll sell quick.
 
Yeah the forklift would make it easy...I didn't have that option, rolling the old cable back up is a bit*h!

"its a nasty mess and a three man job. keep a 2x4 on hand n a 2lb sledge to straighten the lays on the reel out. don't use your hands! you have to have keep tension on the reel. forklifts work the best if you have some holes already drilled in the end of the forks as you can use bull pins to keep the reel from sliding off while using another long 2x4 as a breaking lever. wear old clothes and throw away gloves"
 
Yeah the reason the nuke plant doesn't want AR rope is because of the construction, the outer and the core are spun in opposite directions, thats how they get the anti-rotational feature, unfortunately this causes alot of extra wear because the outer and the core still rotate, just against each other.
 
Truck your a pretty smart ole bugger, I checked at class today and what you just stated is the same thing I was told about AR / weaker and erliar fatigue. If you fly a man basket swl is 7to1 with regular rope and 10to1 with AR. That rope spinnin up on a whip line sounds like somthin else multi parts you bet. single part ??? Watch that ole girl top top bottom to bottom/ You want a man that knows his beans. Basil @ West Coast Wire Rope in Seattle/ He will send ya in right direction and enjoys helpin a fella out. Hes also a riggin instructor. I can dig up his number if you like/ just tell him your in a pinch and need the lowdown cause your wires gettin' jiggy on ya. What part of the Silver State ya workin outta ? If I could find work I'd venture over that way, its gettin harder to run with the young guns, I found that out this summer. Later guys
 
I did not say old/ I said ole. remember don't pull that lever unless we are clear on the signal. It must be your dad rubbin off on ya that had me thinkin you were a little older, I meant it with respect. Take care Truck
