How to install cable trays fastest

Using pre-planned routes, proper supports, and quick-connect systems like Hermi® Fast Joint significantly speeds up cable tray installation.

Plan and Prepare

Efficient installation starts with detailed planning. Review approved shop drawings to determine tray routes, dimensions, support types, and layers. Check for potential clashes with HVAC, plumbing, or fire systems and resolve them before starting work.

Mark the tray path using a laser level or chalk line to ensure straight alignment, which reduces adjustments during installation. Pre-inspect the area for obstructions and ensure all materials and tools are on-site to avoid delays.

Choose the Right Supports

Select mounting methods based on location: Wall Mounts (Cantilever Brackets): Drill and anchor brackets to walls, ensuring they are level. Ceiling Mounts (Trapeze Hangers): Use threaded rods and Unistrut channels to suspend trays, leveling carefully. Spacing supports correctly (typically 1.

5–3 meters apart) prevents sagging and reduces rework.

Use Fast-

Connect Systems

Traditional bolts and nuts can slow installation. Hermi® Fast Joint or similar quick-connect systems allow tray sections to snap together in about 1 minute per connection, compared to over 2 minutes with bolts. These systems require minimal tools, reduce material waste, and allow easy adjustments or dismantling if needed.

Efficient Tray Handling

Cut and Deburr in Advance: Measure and cut trays to length, then deburr edges to prevent cable damage. Align Before Tightening: Place trays on supports and connect with splice plates, keeping sections straight before final tightening. Use Rollers for Long Runs: For ladder-type trays, cable rollers help lay cables smoothly, reducing installation time and preventing kinks.

Final Checks

After installation, verify alignment, secure all fasteners, and ensure proper spacing between layers if multiple trays are stacked (minimum 30 cm recommended),. Conduct a quick inspection to confirm no interference with other systems and that all trays are level and stable. By combining pre-planning, proper support selection, and fast-connect systems, you can significantly reduce installation time while maintaining safety and compliance.
