Quick Installation of Cable Tray Supports

Use center-hung supports, proper spacing, and fast-connection systems like Hermi® Fast Joint to speed up cable tray installation.

Plan and Prepare

Before installation, review the project layout and determine the cable tray route. Mark support points using a chalk line or laser level, typically every 1. 5 to 3 meters, depending on tray type and load requirements.

Ensure the pathway is clear of obstructions such as pipes or HVAC ducts. Gather all necessary tools and materials, including mounting brackets, threaded rods, anchor bolts, and grounding straps. Choose Efficient Support MethodsCenter-hung supports allow cables to be deposited from both sides, reducing handling time and simplifying installation.

Pre-fabricated wall arms or ceiling struts can save time compared to custom-fabricated supports. Maintain maximum load per hanger (typically 318–340 kg) and adhere to manufacturer-specified support spacing to prevent sagging.

Use Fast Connection Systems

Innovative products like Hermi® Fast Joint allow cable trays to be connected without traditional bolts and nuts, reducing connection time from over 2 minutes to about 1 minute per joint. These systems are tool-free or require minimal tools, provide smooth connections, and can be easily dismantled and reused. Using such fast-connection systems also minimizes material waste from cut trays.

Installation Tips

Snap lines and mark bends or risers to ensure accurate alignment. Pre-cut and deburr trays to avoid delays during assembly. Select the right tray type: ladder trays for large power cables, ventilated troughs for smaller control cables, and corrosion-resistant materials for harsh environments.

Follow NE

C Article 392 and local codes for fill ratios and grounding requirements to ensure safety while maintaining speed.

Optimize Workflow

Work in teams to install supports and trays simultaneously. Pre-assemble sections of trays on the ground before lifting them into place. Use threaded rods and adjustable brackets to quickly level and secure trays.

By combining proper planning, center-hung or pre-fabricated supports, fast-connection systems, and efficient workflow strategies, you can significantly reduce installation time while maintaining a safe and code-compliant cable tray system.
