How to make the cable tray angled

Cable trays can be angled using adjustable corner pieces, elbow joints, or angled support brackets to ensure proper load distribution and cable management.

Using Angled Support Brackets

Support brackets can be installed at an angle to improve load distribution and create additional space beneath the tray for cable routing. Angling the brackets helps reduce sagging, especially when supporting heavy or dense cabling, and can enhance the overall aesthetics of the installation. However, it is crucial to ensure that the angle does not compromise the structural integrity or load-bearing capacity of the tray system, and brackets should be installed according to manufacturer specifications and safety standards.

Adjustable Corner Pieces and Elbow Joints

For precise angle adjustments, use adjustable corner pieces or elbow joints: Adjustable corner pieces (SRS) can be inserted into the tray and secured with screws, allowing angles from 0° to 75°. Elbow joints (RVS) allow horizontal orientation changes from -90° to +90°, enabling smooth transitions around obstacles or elevation changes. These components are designed to maintain cable integrity while providing flexibility in routing.

Calculating Offsets and Bend Angles

When routing trays around obstacles or changing elevation, calculate the required offset using the horizontal run, bend angle, and available space. Common bend angles include: 15° and 22. 5°: Ideal for thick or high-voltage cables with large bending radii.

30°: Standard angle balancing space efficiency and ease of cable pulling. 45°: Suitable for tighter spaces or quick elevation changes. 60°: Used in highly confined areas.

Using a cable tray offset calculator can help determine the sloped section length, cut marks, and horizontal run required for accurate installation.

Best Practices

Ensure all components are compatible and tested together as a system. Maintain proper spacing and support to prevent sagging or overloading. Follow relevant standards such as BS EN 61537 for cable trays and BS 6946 for channel support systems.

Avoid using cable trays as walkways or supports for personnel to prevent damage and ensure safety. By combining angled brackets, adjustable components, and careful offset calculations, you can achieve a safe, efficient, and visually organized cable tray installation.
