Cable tray bend cutting method

Cable trays can be bent and cut on-site using mechanical tools, fabricated mitered bends, or specialized bending machines, with proper safety precautions to ensure smooth edges and structural integrity.Cutting Cable TraysTools and Safety:Use an angle grinder with a cutting disc, hacksaw, or band saw suitable for the tray material and thickness .Always wear Kevlar gloves, eye protection, and appropriate PPE to prevent injuries from sharp edges .Protect surrounding materials from sparks and overheating during cutting . Procedure:Measure and Mark: Determine the required length and mark the cut line using a measuring tape and marker .Cut Flanges and Base: For fabricated bends, cut the side flanges at a 45-degree angle and notch the base to allow the tray to bend without deformation .Deburr Edges: Remove any burrs or sharp edges to prevent cable damage and ensure safe handling .Optional Rust Protection: Apply cold galvanizing spray on cut edges for corrosion resistance .Bending Cable TraysMechanical Bending:Use a cable tray bending machine for precise bends, especially for 90-degree internal or external bends .For small adjustments or emergency bends, a metal bar or crimping tool can be used to manually bend the tray . Fabricated (Mitered) Bends:Create a 90-degree elbow by making two 45-degree cuts on the tray sides and notching the base .Fold the tray along the notched lines to form the bend, then fasten with bolts or additional supports if needed .This method works for both horizontal and vertical bends, adjusting the cut location depending on the bend orientation . Best Practices:Always plan bends and cuts according to the installation layout to minimize on-site adjustments .Use manufacturer guidelines for optimal cutting intervals and bend radii to maintain structural integrity .Ensure bends do not create sharp edges inside the tray that could damage cable insulation . By following these methods, cable trays can be safely and efficiently cut and bent to fit complex installation layouts while maintaining durability and protecting cables.
