How to install riveted cable tray elbows

Riveted cable tray elbows are installed by aligning the elbow with the tray, securing it with rivets, and ensuring proper support and load distribution according to manufacturer guidelines.

Preparation and Safety

Before installation, offload and handle trays carefully to prevent damage. Use overhead cranes or forklifts with proper slings, avoiding direct attachment to the tray itself, and ensure bundles are lifted individually to prevent crushing the siderails . Store trays on dunnage to keep them off the ground and prevent moisture contact.

Tools and Materials Needed

• Rivet gun or pneumatic riveter
• Rivets compatible with the tray material
• Measuring tape and level
• Support brackets or hangers
• Safety gear: gloves, goggles, and hard hat

Installation Steps

1. Position the Elbow: Place the riveted elbow at the desired angle, typically 45° or 90°, connecting two straight tray sections. Ensure the elbow aligns with the tray's routing path .
2. Align and Support: Use temporary supports or hangers to hold the elbow in place. Maintain proper spacing between supports, generally 3.6 meters maximum, and ensure the load does not exceed the tray's rated capacity (318–340 kg per hanger), .
3. Fasten with Rivets: Drill or use pre-punched holes to attach the elbow to the tray sections. Insert rivets and secure them using a rivet gun, ensuring a tight and flush connection. Check that the elbow is stable and properly seated.
4. Check Continuity and Clearance: Verify that the tray path is continuous, with no gaps or misalignment. Ensure there is sufficient clearance for cables and that the elbow does not interfere with other equipment.
5. Final Support and Inspection: Install permanent hangers or brackets to support the elbow and adjacent tray sections. Inspect all rivets and connections for tightness and alignment. Ensure compliance with relevant electrical codes and manufacturer specifications .

Tips for Quality Installation

• Avoid over-tightening rivets to prevent deformation of the tray.
• Use elbows with the correct radius to minimize cable stress.
• For complex bends, consider professional fabrication techniques, including bending and welding, if applicable .
• Maintain proper ventilation and spacing to prevent corrosion or moisture accumulation. By following these steps, riveted cable tray elbows can be installed securely, ensuring a safe and durable cable management system.
