The Crosby G2140 Alloy Bolt Type Anchor Shackle 114 is engineered for demanding lifting and rigging tasks in demanding environments such as those found around Houston, including operations linked to Holloway Houston. This robust anchor shackle combines alloy steel construction with a bolt-type design to deliver reliable performance under severe loads.
Operators and project planners specify this shackle when consistent strength and secure attachment points are essential. Its 114 kN working load rating and compliance with recognized standards make it suitable for offshore, construction, and transport applications where safety and traceability are non-negotiable.

Anchor Bolt Type Design and Load Path Efficiency
The anchor bolt type configuration positions the pin axis close to the shackle body, reducing bending moments and enabling a more direct load path. This geometry helps maintain structural integrity when lifting rigging from edges, corners, or preinstalled anchors in Houston projects.
The bolt-style engagement allows for controlled tightening, which supports consistent preload and minimizes the risk of loosening under vibration. When paired with grade-matched attachments, the Crosby G2140 Anchor Shackle maintains predictable behavior under cyclic stresses.
Alloy Steel Composition and Corrosion Protection
Alloy steel in the G2140 enhances toughness at low temperatures and provides resistance to crack propagation during impact loading. This is critical for lifting operations around Houston facilities where temperature fluctuations and exposure to moisture are common.
Hot dip galvanizing adds a thick metallic zinc coating that protects the base metal and extends service life in harsh industrial atmospheres. Routine inspections for coating integrity and pitting remain essential maintenance practices for anchor shackles used near coastal environments.
Inspection, Certification, and Traceability for Holloway Houston Projects
Each Crosby G2140 Anchor Shackle 114 typically arrives with traceable test reports and manufacturer markings that confirm dimensional accuracy and rated capacity. Third-party certification further supports compliance when these components are used in safety Class lifting configurations.
Regular visual and magnetic particle inspections help identify fatigue, cracks, or distortion, especially at the bow and near the threads of the bolt-type screw. Establishing a documented maintenance schedule aligns with best practices for mobile cranes and overhead lifting equipment managed by Holloway Houston teams.
Compatibility and Attachment Considerations
Selecting appropriate shackles for lifting eyes, hooks, or anchor points requires matching pin diameter, thread pitch, and overall geometry to the connected components. The G2140 design limits the risk of accidental disengagement when installed correctly with hardened washers and proper torque procedures.
Overloading, side loading, or using the anchor shackle in a twisted configuration are common misapplications that can dramatically reduce service life and increase the chance of failure. Training personnel to recognize correct alignment and rated usage ensures safer operations across multiple job sites.
Operational Best Practices and Key Takeaways for Anchor Shackle Use
- Verify the working load limit and ensure loads remain within the 114 kN rating of the Crosby G2140 Anchor Shackle 114.
- Always align the shackle pin axis with the direction of pull to avoid side loading and reduce stress concentrations.
- Use calibrated torque tools when tightening the bolt-type screw and washers to maintain secure engagement without overstressing the alloy steel.
- Implement scheduled inspections for cracks, corrosion, and elongation, especially for assets operating near coastal Houston facilities.
- Maintain clear documentation of test dates, inspection results, and replacement history to support safety audits and regulatory compliance.
FAQ
Reader questions
What is the working load limit for the Crosby G2140 Anchor Shackle 114 in lifting operations around Houston?
The Crosby G2140 Anchor Shackle 114 has a working load limit of 114 kN, which is roughly equivalent to 25,600 pounds force, and this rating applies when used in line with manufacturer instructions and appropriate safety factors.
Is the G2140 Anchor Shackle suitable for offshore or marine environments near Houston and does the galvanization provide sufficient protection?
Yes, the hot dip galvanized finish offers strong corrosion resistance for offshore and marine lifting applications; however, periodic inspections for coating wear and surface pitting are recommended in saltwater exposure conditions.
Can this anchor bolt type shackle be used with synthetic slings or only with wire rope and chain attachments?
The Crosby G2140 is designed to connect lifting hardware such as wire rope, chain, and lifting eyes; direct use with synthetic slings is not typical and may require specialized cradles or protection to prevent damage to the shackle and load.
What verification documents should be requested when sourcing this shackle for critical Holloway Houston projects?
Request manufacturer test reports, material traceability, third-party certification marks, and proof of conformity to standards such as CE and ISO 4309 to ensure that the anchor shackle meets project safety and regulatory requirements.
