About 9 Part Wire Rope Slings
9 Part Wire Rope Slings
Holloway Houston 9 Part wire rope slings are designed for high-capacity lifting in industrial, offshore, and heavy rigging applications. Each sling is formed by braiding three 3-part wire rope sections into a single body, improving load stability and weight distribution. All components use Extra Improved Plow Steel (EIPS) with an Independent Wire Rope Core (IWRC) to reduce crushing, kinking, and surface wear. This multi-sling design supports vertical, choker, and basket hitches while maintaining controlled flexibility. Slings are proof-tested to 2x the working load limit and follow a 5:1 design factor. Custom configurations are available based on specific lifting requirements.
Design and Materials
Each 9 Part wire rope sling is formed by braiding three 3 part wire rope slings into a single integrated structure. This braided design distributes loads across multiple rope paths, reducing stress concentration while maintaining flexibility for complex rigging configurations.
Performance Under Different Hitch Types
The strength and flexibility of 9 Part slings make them highly effective in all standard hitch configurations:
Vertical Hitch
Provides full vertical capacity for standard lifts where a single leg is required. This configuration is commonly used for straight lifts of uniform loads and allows for predictable load distribution while minimizing stress on the sling.
Choker Hitch
Wraps partially around the load, improving grip and stability while slightly reducing rated capacity. This method is effective for irregular or cylindrical loads, providing the sling stays in place during lifting and prevents shifting or rotation that could compromise safety
Basket Hitch
The sling is looped under the load, utilizing both legs for lifting, which can nearly double the effective rated capacity. It is ideal for heavy or bulky items, providing balanced weight distribution and reducing stress on individual strands for safer, more controlled lifting operations.
Key Features & Benefits
Each 9 Part Wire Rope Sling is designed for dependable lifting performance across heavy-duty applications. The braided construction combines strength, flexibility, and balance for safe and efficient load handling.
Maximum Load Protection
The multi-part braided manufacture spreads lifting force across a larger bearing surface, reducing pressure points..
Better Load Control
Conforms easily to uneven or curved load shapes, allowing smooth and balanced lifting without any load movement during operation.
Flexible Handling
The 9 part braided design maintains flexibility while providing consistent performance across different lifting configurations, simplifying rigging and storage.
Improved Rotation Resistance
Braided construction helps minimize twisting and rotation under load, allowing the sling to maintain its natural shape through repeated use cycles.
Custom Configurations
Each sling can be fabricated to required diameter, length, and lifting capacity based on application-specific needs.
Compliance Ready
Every sling includes a permanent metal identification tag displaying Working Load Limit, length, and serial number per ASME B30.9 and OSHA 1910.184 requirements.

Safety, Inspection and Maintenance
Regular inspection maintains the performance and safety of 9 Part wire rope slings. Before each use, check for broken wires, kinks, corrosion, or crushed strands that may affect sling strength. Examine end fittings for wear, cracks, or loose connections. Because of their multi-part braided structure, these slings can conceal internal damage, so visual inspection should be combined with periodic professional examination per ASME B30.9 requirements..
Keep slings clean, dry, and properly lubricated to reduce friction between wire rope components. When stored, hang slings in designated areas to prevent tangling or contamination. Remove any sling from service immediately if it shows signs of overloading, distortion, or damage per ASME B30.9 removal criteria. Proper care for longer service life and consistent lifting performance.
