HG12 Winch Preparing the Winch and Work Area 45-5
The following conditions increase corrosion: acid and alkaline solutions,
gases, fumes, brine and salt air, sulphurous compounds, high humidity, and
temperature. Lubricants are available to reduce the damage caused by
these conditions.
• Keep wire rope from kinking or bending sharply. Kinks and sharp
bends permanently bend wires and strands, ruining the wire rope.
To prevent kinks, remove loops in the wire rope before tightening it, or
it will kink as shown
(1) .
To keep the wire rope from bending sharply, do not route it around
sharp corners and do not wrap it around the load.
• Do not overstress wire rope. Snapping the wire rope by adding or
removing/releasing
(2) the load quickly will shorten its life and lead to
failure.
• Only use the wire rope for the specified job. Wire rope tends to “set” to the conditions of a job. Using it for a different task can
lead to premature failure due to the different bends and stresses.
