Right-angle fixing of mesh cable tray

Right-angle bends in mesh cable trays are achieved using the tray's bending capacity, with supports recommended at the start, end, and midpoint of the bend for optimal load distribution.

Creating Right-Angle Bends

Mesh cable trays are designed with flexible wire grids that allow for easy creation of bends, including 90° turns, without cutting or welding the tray . The wires can be separated and bent to form the desired angle, making it suitable for routing cables around corners or obstacles.

Support Placement

For right-angle bends, it is critical to position supports correctly to maintain structural integrity and prevent sagging:

• Start and end of the bend: Place supports at the beginning and end of the 90° turn to stabilize the tray and prevent deflection .
• Midpoint of large-radius bends: For wider or heavily loaded bends, a support in the middle of the curve is recommended to distribute the load evenly and maintain cable alignment .
• Coupler positioning: If using couplers to join tray sections, place them at approximately 1/5th of the span for maximum performance. Avoid placing supports directly under couplers to prevent stress concentration .

Additional Considerations

• Minimum bend radius: Ensure that the bend radius does not exceed the cable manufacturer's recommended minimum to avoid damaging the cables .
• Load capacity: Right-angle bends may slightly reduce the permissible load compared to straight sections. Check the tray's load rating and adjust support spacing accordingly .
• Installation sequence: Install supports before routing cables to prevent deflection and ensure proper alignment through the bend . By following these guidelines, mesh cable trays can safely accommodate right-angle turns while maintaining cable integrity and system reliability. Proper support placement and adherence to bend radius recommendations are essential for long-term performance.
