Vertical Installation and Fixing Brackets for Cable Trays

Vertical cable tray sections are typically supported using wall-mounted U brackets or suspension rods with hoisting frames or cross arms, spaced every 1. 5 to 2 meters for stability. Types of Vertical Support BracketsWall-mounted U brackets ("riding horse" type) are ideal for vertical cable tray installations against walls.

They provide strong support and allow convenient maintenance, with each bracket typically secured using two iron expansion bolts for robust anchoring. Suspension rods with hoisting frames or cross arms are used when vertical support is needed from ceilings. Hoisting frames are suitable for smaller trays, while cross arms provide stability for larger, heavier trays.

Each rod connects the ceiling support to the tray's crossbars, ensuring structural integrity.

Materials and Surface Treatments

Brackets and rods are commonly made from Q235 carbon steel or stainless steel (201, 304, 316 grades). To enhance durability and corrosion resistance, surface treatments include: Hot-dip galvanizingFireproofingElectrostatic powder coatingAluminum-magnesium-zinc plating Installation GuidelinesSpacing: Vertical supports should be installed every 1. 5 to 2 meters along the cable tray.

Anchoring: Use appropriate expansion bolts or fasteners suitable for the wall or ceiling material. Load Considerations: Ensure the support can handle the weight of the cable tray and cables, including any additional imposed loads such as wind, ice, or short-circuit forces. System Integration: Brackets should be compatible with the cable tray system to maintain electrical continuity and grounding.

Best Practices

Follow relevant standards such as BS EN 61537 for cable tray systems and BS 6946 for channel supports. Ensure installation is performed by qualified personnel familiar with electrical safety and local building codes. Consider environmental factors like moisture, corrosive substances, or temperature variations when selecting materials and finishes.

By selecting the appropriate vertical brackets, spacing, and materials, vertical cable tray sections can be securely installed, ensuring both mechanical stability and long-term durability.
