Installing cable trays with reverse bends

Reverse bends in cable trays can be achieved by careful measurement, cutting, and bending of the tray, often reinforced with gussets for stability.Step-by-Step Process1. Marking and Measuring Begin by marking the tray where the reverse bend is required. For wire mesh trays, measure the offset distance and the angle of the bend. For solid trays, determine the lip removal and gusset placement to maintain structural integrity . 2. Cutting the Tray Use a hand grinder, file, or bolt cutter to remove the tray lip or cut side wires as needed. In wire mesh trays, only partial cuts are often required to allow bending without compromising the tray's protective coating . Ensure safety equipment is used during cutting. 3. Forming the BendFor a horizontal reverse bend, flatten the tray lip at the bend point using a blunt object or press.Gradually bend the tray to the desired angle, typically 90° or as required for the installation .For wire mesh trays, bend the cut wires to form the offset, ensuring the bend radius is smooth to prevent cable damage . 4. Reinforcing the Bend Attach a gusset or reinforcement piece to the bend. Cut a piece of tray to the required size, remove one lip if necessary, and bolt it to the bend. This ensures the reverse bend maintains its shape under cable load . 5. Assembly and Installation Secure the bent tray to supports using clamps or brackets. For wire mesh trays, universal clamps or built-in tabs can be used for quick installation without additional tools . Check alignment and spacing to ensure proper cable routing.Tips for Professional ResultsAvoid cutting all wires completely in wire mesh trays; partial cuts allow flexibility while maintaining strength .Measure twice before cutting to ensure accurate reverse bend placement.Use protective caps on cut ends to prevent injury and maintain corrosion resistance .For complex bends, practice on a scrap piece of tray to refine technique. By following these steps, you can create precise reverse bends in both wire mesh and solid cable trays, ensuring safe, professional, and structurally sound cable routing .
