How to install cable tray supports using round pipes

Cable trays can be securely installed using round pipes as hangers by following proper alignment, washer, and clamp procedures to ensure load support and safety.Step-by-Step Installation

1. Plan the Route Before installation, mark the cable tray route according to your site layout, considering clearance, load capacity, and cable separation requirements. Proper planning ensures smooth cable installation and maintenance later. 2. Prepare Round Pipe Supports Use threaded round pipes or rods as vertical supports. Ensure the pipes are cut to the required length to reach from the mounting surface (ceiling or wall) to the desired tray height. 3. Install Washers and Clamps Place a round washer on each threaded rod before lifting the tray section. Insert the rod through the holes in the tray clamp (SC or DC type). Place a second washer and hex nut on the rod, then adjust the tray to the desired elevation. Thread the upper nut down to secure the clamp in place, ensuring the washer is positioned between the nut and clamp for stability . 4. Use Double Ladder Hanger Clamps for Adjacent Trays If supporting two trays side by side, use double ladder clamps (DC). Thread the upper hex nut onto the rod about 50 mm above the existing tray, slide a washer and half of the DC clamp over the tray side rail, lift the new tray, and secure with the remaining nuts and clamp section . 5. Maintain Proper Support Spacing Center-hung tray supports allow easier cable installation. Maximum load per hanger is typically 318–340 kg, with support spacing up to 3.6 meters. For standard installations, spacing between supports is usually 1.5–3 meters depending on tray type and load . 6. Align and Level Trays Ensure trays are straight and level. Use connectors and fittings to join sections, and handle materials carefully to avoid coating damage. For long runs, cable tray rollers can help lay cables smoothly without kinks . 7. Final Checks Verify all nuts, washers, and clamps are tight and that the tray is stable. Confirm that the installation complies with relevant standards such as BS EN 61537 for cable trays and BS 6946 for channel supports . By following these steps, cable trays can be safely and efficiently installed using round pipe supports, ensuring proper load distribution, alignment, and accessibility for future maintenance.
