Side installation of cable trays involves securely mounting trays along walls using brackets or hangers, ensuring proper alignment, support spacing, and adherence to approved drawings and safety standards.

Planning and Preparation

Before installation, review the approved shop drawings to confirm tray layout, dimensions, and mounting heights ( ). Inspect all materials, including trays, brackets, and accessories, for damage or defects, and ensure they meet project specifications ( ). Prepare the site by checking wall conditions, ensuring clearance for cables, and coordinating with other trades to avoid interference ( ).

Mounting Supports

For side-mounted trays, use wall brackets or side supports. Common methods include trapeze supports, cantilever brackets, or direct wall-mounted brackets ( ). Install vertical hangers or brackets at intervals recommended for the tray type and load, typically 1.5 to 3 meters apart, depending on the tray material and cable weight ( ). Ensure brackets are level and securely anchored to the wall.

Tray Installation

1. Position the tray along the wall, aligning it with the brackets or hangers.
2. Attach tray clips or fasteners to the brackets. Depending on the system, clips can be installed inside or outside the tray, allowing minor horizontal adjustments ( ).
3. Check alignment and level of the tray before fully tightening fasteners. Use a spirit level to ensure the tray is straight and properly supported ( ).
4. Install connectors and fittings for long runs, ensuring smooth transitions at joints and corners ( ).

Safety and Quality Checks

• Clearly identify each tray section by feeder name or branch number ( ).
• Inspect all installed trays, brackets, and grounding connections for compliance with approved designs and standards ( ).
• Ensure that the installation does not interfere with other services and maintains proper cable separation ( ).

Additional Considerations

• For heavy loads, consider center-hung supports to allow easier cable placement from both sides ( ).
• Avoid using trays as lifting points during handling; always use proper lifting equipment and dunnage to prevent damage ( ).
• Maintain proper spacing and support to prevent sagging and ensure long-term stability ( ). Following these steps ensures a safe, compliant, and durable side-mounted cable tray installation suitable for industrial, commercial, or plant environments.
