This is an " Inside baseball" type post but just wondering if anyone else has run in to this . Most everyone knows that the no spin (rotation resistant) cable is more work to use . Its damaged easier , Takes more work to control unraveling and so on . The stuff bleeds sticky oil / internal lube . But I have seen on more thing not mentioned by some . It's this time of year that the problem shows up . During the summer the internal lube is a mess when you handle the cable , You better have some cheap gloves you can afford to throw away . That lube stains your clothes , Pretty gummy stuff . But other than that , no problem . However in colder temps that goo will stick on things and build up . Twice in the last few years the build up has gotten so bad that it coats the inside of the Two block weights . Then when hoisting a load the two block weight sticks to the cable . Most of the time the the two block system will slam the brakes on . Then it takes a bit to figure what just happened because the weight most time falls down back down where it belongs (Rental Customers love that) . Had one case when swinging iron that the weight stuck and the brake set a tad late .The weight broke a chunk out of a poly sheave then pieces of the weight came crashing to the ground . Company has done a couple of things to combat this . Using two block weights with a larger hole in the center seems to be the best . Brake parts cleaner to wash the goo out works too if you have the time and space to boom down . Yeah I know , One more thing to worry about in this already dangerous biz
I haven't seen that happen...YET, but can see where it would. That cable is NASTY to handle
Had one machine this summer that had new cable put on , In the 103* heat it actually made an oil mess on the deck . Op had mechanics look at the winch to make sure it wasn't leaking .
noticed the same probs you are talking about. freezing cold weather sets up the lube in the a2b weight-sticky operation, seemed to have solved the problem in 2 ways. opened up the hole in the a2b weight and chamfered the hole a little more and after trying several brands of cable settled on flex-ex 19 by leschen (i believe). seemed to have a more manageable amount of lube. regards, tom.
we have a crane that the pulleys are coated in the groove with the gunk, I noticed one day while greasing. Wow this cable has cut into the pulleys. No wait a minute they're steel. That would've taken some serious weight. Scraped on the pulley to discover the gunk. Later on I noticed the line had little slivers sticking out, like a frayed line. NOW WHAT! It was the line, picking up the dried gunk.
I found that stiff dried grease layered in the tip sheave grooves of several luffers, and I scrap as much as I could off with a putty knife. I don’t like looking up and seeing something odd on the hoist line and then have to go thru all the trouble of laying the rope down or somehow getting it where it can be seen clearly that it’s not a defective rope. It’s the particular kind of grease that is used by some of the rope manufacturers that does that in certain climates. It’s annoying at best, but it get’s the point across to the op’s and the job site personnel that the rope should be always be monitored very closely.
