Why not use wire rope and cover the winch? I covered mine with black heavy-mil plastic sheeting with some bumgees.

I could not be without a winch after having the past 3 vehicles with them.

BTW, Christo used a 8000 Lb winch on the shortbus.

After a couple cups of coffee my brain cells started firing. I might be remembering it wrong, that magnesium chloride does not corrode galvanized steel as bad as NaCl, so this might be OK.

BTW, if anyone wants to see what CDOT said about the matter:

Dave,

You worry more than me, and that's saying something

Don't forget, the synthetic rope on the XD9000 has two sections of the nylon rope cover on it that if you spool the rope in correctly covers up the 1st layer of the rope 100% - I did that for UV protection but hopefully it helps with Mag Chloride protection as well

The other option is we can throw 90' of 7/16" wire rope on there (assuming it will fit) or 150' of 5/16" wire rope from my M8274 and I'll throw the synthetic on the M8274.

Another option is a cover...The Warn covers won't work because the winch mounts feet forward instead of down. But there are companies that make them or you can make your own.

The good news is, the synthetic rope hasn't seen much sunshine OR mag chloride in about 2 years

Looks like reading a bit more about the studies of corrosion of mag chloride often metal samples are suspended with nylon fishing line. Check mark in favor if synthetics.

Second, I had another a-ha moment looking outside at lunch. The city plow truck drove down Peoria and guess of what the tank in back holding the mag chloride was made?

Plastic!

So I looked that up, most likely polyethylene, which is one of the recommended materials for holding mag chloride. Duh.

Guess what, synthetic rope is made typically from materials like Dyneema. Which is UHMW, which is ultra high molecular weight polyethylene! So concludes todays chemistry lesson, crisis averted. Whew.

BTW, does not change my concern about aluminum and so I'm sticking with plastic fairlead rollers instead of aluminum...





P.S., sorry Tom.

No worries, I have a winch now just want a faster on and one with a remote box. I have been looking on CL and found a couple but haven't pulled the trigger yet.

Fairlead rollers should be made from virgin teflon. If you research it a bit, Dave, I think you'll find that teflon will survive chemical abuse as well as the heat generated between the fairlead and the synthetic rope during the winching process.
