> My understanding is that EHS is "galvanized steel cable", which is not the
same as wire rope.
Rope is "a strong, thick line or cord, commonly one composed of twisted
or braided strands of hemp, flax, or the like, or of wire or other material".
And technically, it's only cordage above one inch in circumference and below
10 (bigger-around than that is a cable).
Wire rope is a generic term used to describe just what it is. In amateur
circles we tend to use several different terms for the same thing; e.g. guy
wires, guy cables, etc.
> While they might have the same breaking strength, other
characteristics may be quite different, such as abrasion resistance.
Umm, I'm not sure about the abrasion resistance but each wire rope is
characterized by the material, its lay (either right or left), the number of
strands and the number of strand bundles that make up the completed wire rope;
most crank-ups use 7x19 wire rope because all of the small strands make it
easily bendable and flexible so it can pass over pulleys many times without
> Rohn specs call for EHS, not wire rope. I wouldn't fool around with
other than what the spec calls for.
Yep - the LXC Prime Directive still applies: DO what the manufacturer says.
BTW there are 7-8 different grades of wire rope for a given size; e.g.
1/4" - galvanized, utility grade, stainless steel, EHS, etc. - and it's really
important to use the right grips with the right wire rope. They are NOT
