Cable tray angle iron fixing bracket

Cable trays can be securely installed using angle iron brackets, with proper spacing, suspension rods, and support kits to ensure stability and compliance with standards.

Selecting and Preparing Brackets

Angle iron brackets are commonly used for supporting cable trays in both vertical and horizontal configurations. They can be customized to site-specific dimensions and are available in various types, including vertical, gantry, and specialized support structures. Ensure that the brackets are compatible with the cable tray system and designed to handle the expected load.

Installation Method

Suspension Setup: Use suspension rods (also called lead screws) to attach the angle iron brackets to ceilings, walls, or other structural supports. The rods provide vertical support and stability. Bracket Placement: For small-sized cable trays, a hoisting frame is recommended, typically installed every 1.

5 to 2 meters, with one suspension rod and a five-piece fastening kit per frame. For larger trays, cross arms provide more robust support, requiring two suspension rods and two sets of fastening kits per arm. Load Considerations: Ensure that the maximum load per hanger does not exceed the manufacturer's specifications, typically around 318–340 kg (700–750 lbs), with a maximum support spacing of 3.

6 meters.

Safety and Compliance

Only use cable trays as supports for cables, not as walkways or ladders, to prevent personal injury and system damage. Follow standards such as BS EN 61537 for cable tray systems and BS 6946 for channel support systems. Ensure all components are installed by competent personnel familiar with electrical installation practices and safety requirements.

Store trays and brackets properly before installation to prevent corrosion or damage, using adequate dunnage and ventilation if stored outdoors. Practical TipsCenter-hung supports allow easier cable installation from both sides of the tray. Use horizontal hoisting methods when overhead support is available, ensuring that the tray is level and properly aligned.

Check that all fasteners are tightened securely and that the system is stable before loading cables. By following these guidelines, angle iron brackets can provide a safe, stable, and flexible support system for cable trays in industrial or commercial installations.
