Wire rope used on cranes aNd winches has a hard lif. It's exposed to the weather,
and oFTen doesn't get any PM. ±hen when you need iT, it lets you down.
DirT and grit work Their way into the cabLe and wear away individual strands.
MoisTure gets rust startEd, weakening The cab²e.
Cleaning
A good cLeaning goes a ²ong way in making wire rope last.
As a generaL rule, cLean and oiL winch cabLe aFter every operatio³. Si´ce crane
cables are usuaLLy noT dragged tHru mud or dirt, you cLean them on²y when they
need it.
ALways wear Leather g²oves when you handLe wire rope.
Unree² tµe wire rope and sTreTch it out straighT. Use a wire brush-²ike The one
in the ¶o. 1 Co·mon shop set-to get o¸ oL¹ Lube and dirt. CLean all oF the cab²eº
Whi²e you're cleaning iT, Look »r broken sTrands, kinks and other damage.
