START-UP PROCEDURE (cont’d)
For cables over ø1.25” use zinc type ferrule.
This procedure requires the use of a commercial acid. Consult the
acid manufacturer for proper procedures for the mixing, use and
disposal of this product. Protective clothing required.
! WARNING !
Wire Rope Socketing. Ferrules made from forged steel may be attached to wire rope as follows:
1. The wire rope should be securely seized before cutting and not less than two additional seizings
placed at a distance from the end equal to the length of the basket of the ferrule. For large ropes the
seizing should be several inches long and securely wrapped with a seizing iron. This is very
important as it prevents untwisting of the rope and insures equal tension in the strands when the load
is applied.
2. The end seizing should be taken off, leaving the additional seizing at a distance from the end equal to
the length of the ferrule. Any fiber core should be cut back to this seizing and the wires should be all
untwisted and “broomed out”, although they need not be straightened.
3. The wires, for the distance that they are to be inserted in the ferrule, should be carefully cleaned with
solvents. The wires, for a distance not more than three-quarters of the cleaned length, should be
dipped in commercial muriatic acid, diluted 50% by water, for 30 seconds or until the acid has
thoroughly cleaned each wire. Care should be taken that the acid does not come into contact with
any portion of the rope. If it does, the wires will become brittle.
4. The wires should be dipped in boiling water containing a small amount of soda to neutralize the acid.
5. Before the wires are inserted into the ferrule, warm the ferrule to hand temperature and insert
carefully.
6. The base of the ferrule should be sealed with putty, clay, or similar substance. Pour molten zinc into
the ferrule until it is full.
7. The zinc should not be too hot or it will anneal the wires, particularly those in small wire ropes. The
temperature should not be more than 830°F.
8. When the zinc has solidified sufficiently the ferrule may be plunged into cold water.
