Quickly install cable trays

Use proper planning, the right tray type, efficient support spacing, and fast-assembly connectors to install cable trays quickly and safely.

Plan and Prepare

Before installation, map the cable tray route considering clearance, load capacity, and cable separation requirements. Mark support points using a chalk line or laser level to ensure straight, level alignment. Inspect the area for obstructions like pipes or HVAC ducts and identify locations for bends, tees, or risers to avoid delays during installation .

Choose the Right Tray and Supports

Select the appropriate tray type for your application: ladder trays for ventilation and easy cable entry, perforated trays for lighter loads, or ventilated troughs for smaller control cables . Determine support spacing based on load and manufacturer specifications, typically 1.5 to 3 meters apart. Shorter spacing increases rigidity, while longer spacing saves materials but requires stronger trays .

Use Fast-Assembly Connectors

To save time, consider innovative connectors like Hermi® Fast Joint, which allow tray sections to be connected in about 1 minute per joint without tools, compared to traditional bolts and nuts that take over 2 minutes . These connectors are compatible with standard and cut trays, reduce material waste, and allow easy dismantling if adjustments are needed.

Efficient Installation Techniques

• Pre-cut and deburr trays before installation to avoid delays.
• Use cable tray rollers for long runs to lay cables smoothly and prevent kinks.
• Align trays carefully and secure with brackets or wall arms, ensuring level installation.
• Install grounding and bonding straps as required for safety and code compliance .

Safety and Compliance

Always wear PPE including gloves, safety glasses, and a hard hat. Follow NEC or local electrical codes for tray fill ratios (usually max 50%) and support spacing. Proper planning and adherence to standards prevent sagging, overheating, and future maintenance issues . By combining pre-planning, correct tray selection, fast connectors, and efficient installation techniques, you can significantly reduce installation time while maintaining a safe and code-compliant cable tray system.
