Fixing Cable Trays with Hangers

Cable tray hangers are specialized supports designed to securely suspend or mount cable trays, ensuring safe and organized cable management in industrial and commercial installations.

Types of Cable Tray Hangers

1. G Hanger Support Brackets: Used for overhead support of cable trays, trunking, or baskets, available in sizes like 100mm and 150mm, suitable for standard cable tray systems and ensuring robust suspension .
2. Trapeze Support Brackets: Pre-assembled for quick installation, these provide strong support for cable trays with various widths and drop lengths, commonly used for ceiling-mounted or suspended trays .
3. Stand-Off Brackets: Ideal for mounting cable trays with a specific clearance from walls or surfaces, available in sizes from 50mm to 300mm, allowing proper airflow and access behind the tray .
4. Wire Mesh Hanging Supports: Designed for mesh cable trays, these provide stable suspension from threaded rods and are available in finishes like Electro Zinc, Hot Dipped Galvanized, and Stainless Steel .
5. Hanger & Side Supports: Used to attach trays to walls or suspend them overhead, ensuring secure positioning and preventing sagging or displacement .

Materials and Durability

Cable tray hangers are typically made from pre-galvanized steel, hot-dipped galvanized steel, or stainless steel (A316/A4), offering corrosion resistance and long-term durability in demanding environments . The choice of material depends on the installation environment, such as indoor, outdoor, or corrosive industrial settings.

Installation Considerations

• Overhead Suspension: Use G hangers or trapeze brackets with threaded rods for ceiling-mounted trays.
• Wall-Mounted Support: Stand-off brackets or wall brackets provide secure attachment to walls while maintaining clearance.
• Load Capacity: Ensure the hanger type matches the tray width and cable load to prevent sagging or structural failure.
• Compatibility: Most hangers are compatible with standard cable tray systems, including ladder, ventilated, and solid-bottom trays .

Additional Accessories

Cable tray hangers often work in conjunction with clamps, splicers, hold-downs, and cover clamps to maintain tray stability, protect cables, and facilitate directional changes or branching in the cable system . Using the correct hanger type ensures safe, organized, and durable cable management, reducing risks of cable damage, tripping hazards, and maintenance issues.
