How to install cable trays in the middle

To install the middle section of a cable tray, align it with the existing tray, secure it with splice plates, and ensure proper support spacing and level alignment for safe and stable cable management.

Step-by-

Step Installation1. Plan and Align the Tray Route Before installing the middle section, ensure the tray route is clearly marked using a laser level or chalk line to maintain a straight and level path. This prevents misalignment and sagging in the final installation.

2. Prepare Supports Install the necessary supports along the tray route. For ceiling-mounted trays, use trapeze hangers; for wall-mounted trays, use cantilever arms.

Supports should be spaced according to the tray type and load, typically 1. 5 to 3 meters apart. Ensure all supports are securely anchored to the building structure.

3. Position the Middle Section Lift the middle section into place, aligning it with the previously installed tray section. Ensure the ends of the trays meet evenly without gaps or misalignment.

Handle the tray carefully to avoid coating damage or bending. 4. Connect Using Splice Plates Attach the middle section to the adjacent tray sections using splice plates.

These plates bridge the connection and are fastened with bolts or screws. Make sure the splice plates are tightened evenly to maintain a straight line and prevent the tray from appearing uneven. 5.

Check Level and Alignment After connecting, verify that the tray is level and straight along its entire length. Adjust supports or splice connections if necessary to correct any deviations. 6.

Secure and Inspect Once aligned, ensure all fasteners are tightened and the tray is stable. Inspect for sharp edges or protrusions that could damage cables. Confirm that the tray can safely support the intended cable load.

7. Prepare for Cable Installation With the middle section installed, you can now proceed to lay cables, maintaining proper spacing and bend radius as recommended for the cable type. Following these steps ensures that the middle section of your cable tray is installed safely, aligned correctly, and ready for cable management, providing long-term stability and protection for your electrical system.
