Compacted Wire Ropes with Crimped Outer Strands

Compacted wire rope with decreased diameter yet increased tensile strength

For more Compacted Steel Strand Chinainformation, please contact us. We will provide professional answers.

Compacted wire rope is composed of several wire strands which have gone through crimping wheels to compress and shape the individual wires to form compacted structures or reduce diameters before laying strands around the core. Taking advantage of the compacting process, the surface of outer wires is flattened and the contact area between strands is increased.

Feature:

• Increased wear resistance of wires.
• Smoother bearing surface than traditional wire ropes.
• Increased tensile strength and lateral compression strength.
• Increase metal cross sectional area.
• Decreased blocks groove wearing.
• Decreased construction stretch.
• Less contact pressure onto the sheaves and drums.
• Better fatigue life and low deformation.
• Capable to withstand high load and sock load.
• Easy to handle.

Application:

• Whip hoist rope.
• Pillar crane rope.
• Deck crane rope.
• Offshore crane rope.

• Other various hoist ropes.
• Mining ropes.
• Machinery.
• Marine fishing applications.

Three main types of compacted wire ropes can be offered: general compacted, fiber infilled and plastic injected steel wire rope:

• General compacted wire rope - This is the standard type of wire rope which is construction of normal inner core wire and compacted outer wire or strands.
• Fiber infilled wire rope - With compacted outer surface and added fibers & lubricant inside the rope, fiber infilled wire rope can efficiently reduce the friction between outer strands and inner core, protect the core form corrosion as well as maintain the stability of the rope.
• Plastic injected wire rope - It features special made plastic which is injected in the core of wire for separating the independent wire rope core and each strand totally. As an excellent alternative of traditional lubricant, the plastic reduces the friction and maintenance works.

It is the wire strands, not the total rope that go through the compacting process. But as your request, swage compaction can be applied to the entire rope for flat surface and closer strand gaps.

Compacted Strand Wire Rope

Compacted strand wire rope is a wire rope manufactured from strands which have been compacted or reduced in diameter prior to laying strands around the core into a finished wire rope. There are various known methods for compacting; drawing the strand through a compacting die, roller reduction and rotary swaging are several examples. The compacting process flattens the surface of the outer wires and reforms internal wires of the strand to increase the metallic area of the strand. The result is a smoother bearing surface at the strand crowns and an increase in nominal strength over round strand rope of the same diameter and classification.

Compacted Strand Rope Cross-sections

The entire cross section of a rope is compacted or reduced in diameter following laying strands around the IWRC to produce compacted or swaged wire rope. Rotary swaging is the most common process for compacted rope although other processes may be used. As illustrated the wires and strands of the rope are flattened to produce a relatively smooth and wear resistant outer surface. Compacted rope generally has good wear resistance, crushing resistance and high strength, however bending fatigue life may be reduced by the compacting process.

COMPACTION

To increase the breaking force of our products without increasing the diameter of the rope, we compact the strands, the rope or both in combination. In addition to the greater metal cross section and the resulting higher breaking force, compacted ropes also have smoother strand and rope surfaces.
Compacted strands provide the rope with greater flexibility and minimise both friction and corrosion in the rope. In addition, they reduce the risk of negative imprints in the grooves of the rollers and improve the service life of the rope in the casing of multi-layer winding.
Furthermore, the compaction of the rope increases its pressure stability and, due to a lower tendency to indent and optimised pressure distribution, it improves the properties of the rope for multi-layer winding.

ADVANTAGES

• Increases the metallic cross section and the breaking forces
• Increases the surface contact between individual wires
• Achieves a smoother rope surface
• Improves the contact ratio between the rope and the rope groove
• Reduces the indenting of adjacent rope strands
• Improves the structure stability in the casing of multi-layer windings
