How to retract the cable tray support

Retracting a cable tray support involves safely loosening the mounting hardware, adjusting or removing the support element, and ensuring the tray remains level and secure during the process.

Step-by-Step Guidance

1. Ensure Safety First Before attempting to retract or adjust a cable tray support, de-energize nearby electrical circuits if cables are live, and wear appropriate personal protective equipment (PPE) such as gloves and safety glasses. Confirm that the tray is not supporting excessive cable weight that could cause sudden movement or injury. 2. Identify the Support Type Cable tray supports can include wall brackets, suspended supports, or center suspensions. Understanding the type of support is crucial because the retraction method may vary depending on whether the support is bolted, clamped, or suspended from a ceiling or beam . 3. Loosen Mounting Hardware Use the appropriate tools (wrenches, screwdrivers, or socket sets) to loosen bolts, clamps, or mounting plates that secure the tray to the support. For suspended supports, check if the support uses threaded rods or adjustable hangers that can be retracted or shortened . 4. Support the Tray During Retraction Before fully retracting the support, temporarily support the cable tray using additional brackets, jacks, or a second person to prevent sagging or damage to the cables. Ensure the tray remains level and that cables are not stressed or pinched . 5. Retract or Adjust the Support

• For telescopic or adjustable supports, slide the support to the desired position and tighten the locking mechanism.
• For fixed supports, remove the bolts or clamps completely, reposition the support, and reinstall it at the new location.
• Ensure that the spacing between supports complies with standards (typically 4–6 feet for horizontal runs, not exceeding 5 feet according to NEC guidelines) to maintain structural integrity . 6. Verify Stability and Cable Integrity After retraction or repositioning, check that the tray is level, secure, and properly supported. Inspect cables for any signs of stress, bending beyond the minimum radius, or damage. Re-tighten all hardware and ensure the tray can safely carry the intended cable load . 7. Document Changes Update installation records to reflect the new support positions, especially in industrial or commercial installations where compliance with standards like BS EN 61537 or NEC is required . By following these steps, you can safely retract or adjust cable tray supports while maintaining proper cable management and structural safety.
