A right-angle turn on the side of a cable tray requires proper fittings, support within 150 mm of the joint, and adherence to load and bend radius standards.

Fittings and Components

To create a right-angle turn on a cable tray, you typically use elbow fittings or 90° side bends designed for the specific tray type (ladder, ventilated, or solid-bottom) and width. These fittings allow the tray to change direction horizontally or vertically while maintaining cable integrity and proper spacing. For side-mounted trays, cantilever brackets or wall-mounted supports are used to secure the tray along the wall.

Support Requirements

All changes of direction, including right-angle bends, must be supported in the immediate vicinity of the joint, typically within 150 mm of the elbow or connector. This ensures that the tray can safely bear the weight of the cables and prevents sagging or mechanical stress. Depending on the tray system, supports can include TKS, KTA, or KTUG cantilever brackets, sometimes combined with threaded rod suspensions for additional stability.

Load and Bend Considerations

Ensure the maximum permissible cable weight and tray width are not exceeded. Maintain the minimum bend radius for cables to prevent damage, especially for instrumentation or control cables. For wall-mounted trays, brackets like KTAF 200/300 can be used without additional threaded rods, while ceiling-mounted trays may require DBG 12 or TKSD 20 spacers for reinforcement.

Installation Tips

Use mushroom head bolts or verified fasteners to secure the tray to brackets. Verify that the tray material and finish are suitable for the environment (e.g., galvanized steel, aluminum) to prevent corrosion. For complex routing, consider modular fittings that allow horizontal and vertical changes without compromising structural integrity.

By following these guidelines, a right-angle turn on the side of a cable tray can be installed safely, maintaining proper support, cable protection, and compliance with standard cable tray practices.
