Get this Crosby A-342 5/8" Master Links, 9,000 LBS WLL, G100 Alloy Oblong Master Link - 1014280 from our products. This Crosby master link is designed for demanding lifting and rigging applications where high strength, traceability, and safety are required. The other essential information on this master oblong link is as provided below:
- Size & Capacity: This Crosby masterlink is available in 5/8" size, with an inside length and width of 6" and 3" respectively. The working load limit of this master link is 9,900 lbs, and the breaking strength is 45,000 lbs. These Crosby master links are 100% proof‑tested and fatigue rated to 20,000 cycles at 1-1/2 times the working load limit (WLL).
- Material & Construction: This A‑342 master link is forged from premium Grade 100 alloy steel. It is quenched and tempered for maximum toughness and durability. Each link is individually proof‑tested with specialized fixtures to avoid localized point loading and carries raised lettering indicating size, “Crosby,” and “USA” for full material traceability.
- Compatibility: This master link is ideal for a single-leg chain sling 5/16" in diameter. It is also compatible with a two-leg (double-leg) chain sling, each up to 9/32" (1/4") in diameter. Note: Always ensure the master link’s Working Load Limit (WLL) meets or exceeds the combined load expected in your lift configuration.
- Application: The master oblong link is ideal for multi‑leg sling assemblies in construction, offshore, manufacturing, and heavy‑lift operations. It works seamlessly with chain slings, wire‑rope assemblies, or synthetic web slings where a strong, single connection point is needed.
- Traceability & Testing: This oblong master link comes with a product Identification Code (PIC) to ensure full material traceability. The Crosby links are type approved to DNV ST‑E271‑2.7‑1 Offshore Containers, and incorporate patented QUIC-CHECK deformation indicators for instant visual safety checks.
- Standard Compliance: It meets or exceeds all requirements of ASME B30.26, including identification, ductility, proof load, temperature, and fatigue life, plus critical performance standards not addressed by B30.26, such as impact properties and detailed material traceability.
How to Use It
- Inspect before use for cracks, deformation, wear, and verify Crosby markings and QUIC-CHECK indicators.
- Attach sling legs (chain, wire rope, or synthetic) directly or through sublinks, ensuring all components match the WLL.
- Connect the master link to the crane or hoist hook, ensuring it sits fully in the hook’s bowl.
- Balance the load by evenly attaching sling legs and lifting vertically to avoid side loading or tipping.
- Lift smoothly while monitoring for slippage or imbalance, and keep clear of the load during the lift.
- Inspect again after use for any damage or signs of overstress before storing or reusing.
Safety Considerations
- Always operate within rated WLL to avoid overload.
- Inspect for deformation, wear, corrosion, or cracking before and after each use.
- Remove from service immediately if tension indicators show deformation or if any defects are found.
