Electrician Makes His Own Cable Tray Bend

Electricians can create a 90-degree bend in a steel cable tray using simple tools like a metal bar or crimping tool, without needing a specialized bending machine.

Position the Tray: Place the tray on a stable surface. For internal bends, the tray should be oriented so the bend will form inward.

Apply Force Using a Metal Bar: Insert a sturdy metal bar at the marked point and gradually lift or press the tray to start forming the bend. This method allows you to create a controlled curve without cracking the metal. Crimping for Smoothness: After the initial bend, use a crimping tool along the edges to smooth out the bend and ensure the tray maintains its shape and structural integrity.

Check Alignment: Verify the bend angle with a set square or protractor to ensure it is a precise 90 degrees. Adjust as necessary. Install the Tray: Once the bend is complete and smooth, the tray can be mounted in its intended location.

Tips for Success

Work Slowly: Gradual bending reduces the risk of kinks or cracks in the tray. Use Leverage: A longer metal bar provides better leverage for bending thicker trays. Safety First: Always wear gloves and eye protection to prevent injury from sharp edges or metal fragments.

Practice on Scrap: If possible, practice on a scrap piece of tray to perfect your technique before bending the actual installation piece. This method is particularly useful when pre-fabricated bends are unavailable or when a bending machine is not on site, allowing electricians to adapt quickly and maintain workflow efficiency.
