Description
 

Introduction

 

18x7 Rotation Resistant Wire Rope is a steel wire rope made of 18 strands, each consisting of 7 wires. This design provides excellent resistance to rotation, preventing twisting or spinning under high load and high-speed applications.

 

 

Key Features

 

Torque Balanced Construction

Opposing inner and outer strands eliminate twisting, providing stability and preventing unlaying under heavy loads.

 

Enhanced Flexibility

18 strands offer smoother bending around sheaves, reducing friction and extending rope life.

 

Efficient Spooling

Balanced tension and a smooth surface prevent uneven spooling, preserving rope integrity and ensuring consistent operation.

 

Wear Resistance

Compact strand arrangement increases surface contact, reducing wear on both rope and sheaves for longer service life.

 

 

Customization Options

 

Coating Types: Available in galvanized, polyethylene, PVC coatings, offering extra corrosion protection.

 

Diameter and Length: Customizable diameters and lengths to meet specific application needs.

 

Tensile Strength Levels: Choose from different tensile strength grades such as 1570MPa, 1670MPa, and 1770MPa.

 

Core Design: Available in different core designs such as steel wire core (IWRC) or fiber core (FC).

 

 

Application

 

Port Cranes: Used for lifting heavy loads, preventing rope rotation during frequent operations.

 

Oilfield Drilling Equipment: Hoisting operations under high load and speed, ensuring safe and stable performance.

 

Construction Hoisting: Used in vertical transportation systems for high-rise buildings, ensuring safety during construction.

 

 

FAQ

 

Q: Can this rope be used with swivel joints or free-rotating ends?

A: No. The rotation-resistant wire rope is designed to minimize twisting, but using it with swivel joints or free-rotating ends can reduce its rated strength by 30% to 40%, unless specifically engineered for such applications.

Q: What surface treatments are available?

A: You can choose from bright (bare) or galvanized coatings, depending on your corrosion resistance needs.

Q: Does this product meet any industry standards?

A: Yes. It is designed to comply with ISO 9001 and IATF 16949 quality and safety certifications.

Q: How does the rope perform in harsh environments?

A: The 18x7 construction provides excellent durability, resisting wear, corrosion, and abrasion in demanding conditions.

Q: How does it compare to standard wire ropes?

A: Compared to standard ropes, the 18x7 design reduces rotation, enhancing safety, reducing maintenance, and improving equipment lifespan.

Q: What maintenance is needed?

A: Minimal maintenance is required; periodic inspection and lubrication are recommended to keep the rope in optimal condition.
