Cable tray support and hanger accessories

Cable tray supports and hangers are essential components that securely hold and organize cable trays, ensuring safe, efficient, and durable cable management in various installations.OverviewCable tray supports and hangers are used to mechanically support cable trays, which house and route electrical or communication cables. They are installed on ceilings, walls, floors, or structural beams and are critical for maintaining proper cable alignment, preventing sagging, and ensuring compliance with safety standards .Types of Supports and HangersStand-Off BracketsMount cable trays or baskets with a specific clearance from walls or surfaces.Sizes typically range from 50mm to 300mm .G Hanger Support BracketsDesigned for overhead support of cable trays, trunking, or baskets.Common sizes include 100mm and 150mm .Trapeze Support BracketsPre-assembled for quick installation.Provide robust support for various tray widths and drop lengths, e.g., 100mm or 150mm widths with 500mm drops .Wall and Support BracketsAttach trays to walls or structural elements.Can be used for horizontal or vertical routing changes .Suspended Supports and Centre SuspensionsUsed for ceiling-mounted trays or long spans.Ensure proper load distribution and prevent excessive deflection .Clamps and Hold-DownsSecure trays in environments with vibration or movement.Prevent displacement and maintain cable layout integrity .Materials and DurabilitySupports and hangers are typically made from pre-galvanized steel, hot-dipped galvanized steel, or stainless steel (A316/A4) to ensure corrosion resistance and long-term durability . The choice of material depends on environmental conditions, such as exposure to moisture, chemicals, or outdoor elements.Installation GuidelinesSupport Spacing: Horizontal tray runs should have supports at intervals not exceeding the tray's straight section length, typically around 20 feet for standard trays .Fitting Support: Fittings with radii less than 12 inches should be supported within 2 feet of each extremity; larger radii may require additional center supports .Expansion Joints: Supports should be placed 2 feet on each side of expansion connections to accommodate thermal expansion .Load Considerations: Supports must withstand mechanical loads, environmental factors, and the weight of cables, ensuring safety and compliance with standards like DIN EN 61537 .AccessoriesAdditional accessories enhance support functionality:Splicers: Join tray sections securely.Cover Clamps: Protect cables from external elements.Barrier Strips and Cable Protection Rings: Provide extra safety and organization .Key TakeawaysCable tray supports and hangers are critical for safe, organized, and durable cable management. Selecting the appropriate type, material, and installation method ensures compliance with standards, prevents cable damage, and facilitates maintenance and future expansion. Proper planning of support locations, spacing, and accessories is essential for an efficient cable tray system .
