How to install lifting lugs at the bend of the cable tray

Lifting lugs at cable tray bends should be installed using reinforced attachment points, aligned with the tray's structural members, and secured with appropriate bolts or clamps to ensure safe lifting.

Step-by-Step Installation

1. Identify the Bend Location and Load Requirements Determine the exact bend where the lifting lug will be installed. Check the tray's load rating and the weight of the cable bundle to ensure the lug and tray can safely support the lift . 2. Select Appropriate Lifting Lugs and Hardware Use lugs rated for the expected load. For wire mesh or ladder trays, choose lugs that can be bolted to the tray's side rails or cross members. Smooth-head bolts or SBH splice bolts are recommended to avoid damaging cables . 3. Prepare the Tray for Lug Installation

• For wire mesh trays, bend down the side wall slightly if needed to create a flat surface for the lug .
• For ladder trays, ensure the lug aligns with a cross member or side rail to distribute the load evenly .
• Use a scribe or metal marking tool to mark the attachment points accurately . 4. Attach the Lifting Lug
• Position the lug at the bend, ensuring it is centered and aligned with the tray's structural members.
• Secure the lug using bolts, nuts, and washers. For mesh trays, use two splice plates per length if necessary to reinforce the attachment .
• Tighten bolts to manufacturer-recommended torque to prevent loosening during lifting. 5. Verify Stability and Safety
• Check that the lug is firmly attached and that the tray does not deform under a test load.
• Ensure the lifting angle does not create excessive stress on the bend or tray side rails .
• Always lift using proper rigging techniques and avoid using the tray itself as a lifting point without lugs. 6. Repeat for Additional Lugs For larger or heavier bends, install lugs in pairs on opposite sides of the tray to balance the load and prevent twisting .

Safety Considerations

• Never exceed the tray's rated load.
• Avoid attaching lugs to unsupported sections or thin mesh without reinforcement.
• Inspect all hardware before lifting and ensure compliance with local electrical and mechanical codes . By following these steps, lifting lugs can be safely installed at cable tray bends, allowing secure handling and installation without damaging the tray or cables.
