seizing wire rope ends made in china

Whatever cutting methods your applied, certain precaution - seizing both rope ends must be employed to protect the steel wire ropes from loosening. But carelessly or inadequately seized ends may cause distortion and flattening of the rope. If these loose ropes are applied to works, uneven distribution of loads to the strands may shorten the life of ropes badly. So it is important to seize the wire ropes in the optimal way.

Normally, two methods are widely accepted by our customer. The method one is suitable for wire ropes with diameter over one inch, while the method two is for those with diameter one inch and under.

The diameter and length of seizing wires may different as the diameter of the wire rope. Make sure that the seizing length is no less than the diameter of the steel wire rope.

Generally, one seizing on each side of the cut is sufficient for preformed ropes. But for rotation resistant or non-preformed ropes, no less than two seizing parts are needed with the distance about six rope diameters.

The two widely accepted methods of applying seizing are illustrated in Figures 25A and 25B. The seizing itself should be soft, or annealed wire or strand. Seizing wire diameter and the length of the seize will depend on the diameter of the wire rope. But the length of the seizing should never be less than the diameter of the rope being seized. Normally, for preformed ropes, one seizing on each side of the cut is sufficient. But for ropes that are not preformed or rotation resistant ropes, a minimum of two seizings on each side is recommended; and these should  be spaced six rope diameters apart (Fig. 26).

Proper seizing and cutting operations are not difficult to perform, and they ensure that the wire rope will meet the user’s performance expectations. Proper seizings must be applied on both sides of the place where the cut is to be made. In a wire rope, carelessly or inadequately seized ends may become distorted and flattened, and the strands may loosen. Subsequently, when the rope is operated, there may be an uneven distribution of loads to the strands; a condition that will significantly shorten the life of the rope.

Either of the following seizing methods is acceptable. Method No. 1 is usually used on wire ropes over one inch in diameter. Method No. 2 applies to ropes one inch and under.

Method No. 1:  Place one end of the seizing wire in the valley between two strands. Then turn its long end at right angles to the rope and closely and tightly wind the wire back over itself and the rope until the proper length of seizing has been applied. Twist the two ends of the wire together, and by alternately pulling and twisting, draw the seizing tight.

The Seizing Wire. The seizing wire should be soft or annealed wire or strand. Seizing wire diameter and the length of the seize will depend on the diameter of the wire rope. The length of the seizing should never be less than the diameter of the rope being seized.

Proper end seizing while cutting and installing, particularly on rotation-resistant ropes, is critical. Failure to adhere to simple precautionary measures may cause core slippage and loose strands, resulting in serious rope damage. Refer to the table below ("Suggested Seizing Wire Diameters") for established guidelines. If core protrusion occurs beyond the outer strands, or core retraction within the outer strands, cut the rope flush to allow for proper seizing of both the core and outer strands.

As shown in Figure 1, the utility model comprises main haulage cable 2, wherein the guiding seizing wire 3 that forms of an end drawing-down and the slick and sly steel toe 1 that is connected the steel wire rope two ends constitute with main haulage cable 2 by drawing process, on the slick and sly steel toe 1 through wires hole 11 is set, the diameter of guiding seizing wire 3 is less than main haulage cable 2, the diameter of guiding seizing wire 3 is 2.5MM, be that its suppleness diameter of phi is 0.0595MM, the length of guiding seizing wire is 250CM.

Because the utility model is provided with one section guiding seizing wire 3 on main haulage cable 2, then in use threading apparatus runs into crooked tube wall and will become curved and walk over along tube wall, thereby is more prone to walk the pipeline of pre-buried various band bent angles.

Interesting that Stevenson used the wrong word. Although he came from a family of lighthouse engineers and went with his father to visit some of his father"s projects he was not a sailor. A seizing has never meant a wrapping to prevent a rope"s end from fraying. As the OED definition quoted makes clear, a seizing always involves binding two parts together. As Hans in Texas points out, the normal usage is to "whip" the end of a rope. However, although that is current usage, it is not modern. It"s recorded as far back as the 15th century.
