The cable tray has a right angle bend

A cable tray can achieve a 90° bend using pre-manufactured elbow fittings or on-site bending techniques while maintaining cable protection and proper bend radius.

Pre-

Manufactured 90° BendsFor heavy-duty or standard cable trays, pre-galvanized steel 90° elbow fittings are available. These fittings provide a robust and durable solution for right-angle turns, ensuring secure assembly and compatibility with leading tray systems like Unitrunk. They are designed to maintain structural integrity and long-term reliability in demanding installations, and often include integrated couplers for quick and reliable installation.

On-

Site Bending Techniques

If a pre-manufactured bend is not available, a 90° bend can be made on-site using simple tools such as a metal bar or a cable tray bending machine. The process involves carefully lifting and bending the tray to the desired angle while respecting the minimum bend radius of the cables to prevent damage. For wire mesh trays, bends can also be made using a bolt cutter, which allows live adjustments without compromising cable protection, especially when rubber caps are used to cover cut ends.

Technical Considerations

Bend Radius: Ensure the bend radius is suitable for the type of cables being installed. Larger, high-voltage, or stiff cables require gentler bends to avoid damage. Offset Planning: In some installations, a right-angle bend may be part of a compound offset to navigate around obstacles.

Calculating the correct sloped section length and horizontal run ensures smooth cable routing. Material and Finish: Choose bends that match the tray material (steel, aluminum, or wire mesh) and environmental requirements, such as corrosion resistance for outdoor or industrial settings.

Practical Tips

Always measure and mark bending points along the straight tray before bending. Use appropriate personal protective equipment when performing on-site bends. Verify that the bend allows for easy cable pulling and does not violate the minimum bend radius of the installed cables.

By following these guidelines, a cable tray can safely and efficiently navigate a 90° turn while maintaining cable integrity and installation standards.
