Cable tray lifting ring installation

Cable tray lifting rings should be installed at designated attachment points, ensuring load distribution, secure fastening, and compliance with manufacturer and safety standards.

Selecting the Lifting Points

When installing lifting rings on cable trays, use pre-perforated holes or slots on the tray sides that meet the size and load requirements specified by the manufacturer (e.g., Speed Link SLK or SLS devices) to ensure stability during lifting . Avoid attaching lifting rings to unsupported areas or using the tray itself as a lifting point, as this can cause deformation or failure .

Installation Procedure

1. Inspect Materials: Verify that the cable tray, lifting rings, and associated hardware are free from damage and conform to approved specifications .
2. Position Lifting Rings: Attach the lifting rings symmetrically relative to the tray centerline. For narrow trays, spacing between two lifting points should be at least two-thirds of the tray width to maintain stability .
3. Secure Fastening: Use manufacturer-recommended locking devices, clips, or brackets to attach the lifting rings. Ensure all bolts, nuts, or locking mechanisms are tightened according to specifications .
4. Check Alignment: Confirm that lifting rings are aligned and that the tray remains level when lifted. Misalignment can cause tilting or uneven load distribution .
5. Load Testing: For critical installations, perform a test lift with a controlled load to verify that the lifting rings and tray assembly can safely handle the intended weight .

Safety Considerations

• Only qualified personnel should perform lifting operations, following local electrical and occupational safety codes .
• Use appropriate lifting equipment such as cranes or hoists with rated slings, ensuring slings do not damage the tray side rails .
• Avoid lifting multiple bundles at once unless the tray and lifting rings are rated for the combined load .
• Ensure the lifting area is clear of personnel and obstacles to prevent injury in case of slippage or failure .

Additional Recommendations

• Store trays and lifting accessories on flat surfaces with adequate support to prevent bending or damage before installation .
• Follow manufacturer-specific guidelines for the type of tray (wire basket, ladder, or solid-bottom) as lifting ring attachment methods may vary .
• Maintain documentation of installation, including lifting points, hardware used, and load ratings, for future inspections and maintenance . By following these steps, cable tray lifting rings can be installed safely and effectively, ensuring proper load handling and compliance with industry standards.
