What are some methods for quickly installing cable trays

Using innovative connectors like Hermi® Fast Joint and proper planning can significantly speed up cable tray installation while ensuring safety and reliability.

Plan and Prepare Efficiently

Before installation, map the cable tray route carefully, considering clearance, load capacity, and cable separation requirements. Mark support points and bends using a chalk line or laser level to avoid delays during mounting. Ensure the pathway is clear of obstructions such as pipes or HVAC ducts, and gather all necessary tools and materials in advance, including trays, brackets, couplers, grounding straps, and fasteners.

Choose the Right Tray and Supports

Select the appropriate tray type (ladder, perforated, solid-bottom, wire mesh) based on cable type, load, and ventilation needs. Use pre-fabricated supports like wall arms or ceiling struts, and space them according to manufacturer specifications (typically 1. 5–3 meters apart) to prevent sagging and reduce rework.

Use Fast Connection Systems

Traditional bolts and nuts can be time-consuming. Fast joint systems, such as Hermi® Fast Joint, allow tray sections to be connected in about 1 minute per joint compared to over 2 minutes with conventional methods. These systems require minimal tools, provide firm and safe connections, and can be easily dismantled or reused, improving overall efficiency.

Install with Precision and SafetyAlign trays straight and level, and secure them to supports. Use splice plates or couplers for end-to-end connections, ensuring electrical continuity. Install grounding jumpers across joints if the coupler does not provide continuity.

Inspect all bolts and fasteners with a torque wrench to ensure proper tightness and prevent future sagging or hazards.

Cable Loading Strategy

When pulling cables, load heavier power cables first, followed by lighter control or data cables. Use dividers to separate power and data lines to prevent interference. Secure cables with ties every few meters to maintain organization and allow heat dissipation.

Additional Tips for SpeedPre-cut trays and supports to reduce on-site adjustments. Use teamwork and assembly-line techniques for long runs. Keep all tools and fasteners within easy reach to minimize downtime.

Inspect and plan for expansion or temperature-induced movement using expansion plates every ~30 meters to prevent twisting or buckling. By combining careful planning, proper tray selection, fast joint connectors, and organized workflow, you can achieve the fastest and most efficient cable tray installation while maintaining safety and compliance with NEC/IEC standards.
