Installation method of Italian ladder-type cable trays

Proper installation of Italian ladder cable trays involves careful planning, material verification, secure mounting, and adherence to EN and UL standards for safe and durable cable management.

Material Preparation and Inspection

Before installation, all cable trays, ladders, and accessories should be inspected for compliance with approved material submittals. Any damaged or non-conforming items must be reported and removed from the site. Trays should be stored horizontally on flat surfaces with timber supports at 1-meter intervals and protected from moisture and sunlight to prevent corrosion or deformation.

Italian ladder trays, such as those from Schiavetti Tekno, are available in stainless steel, hot-dip galvanized, and aluminum, ensuring suitability for various industrial environments.

Planning and Layout

Review the approved shop drawings to determine the exact layout, lengths, and locations of ladder trays. Consider load requirements, including current and future cable additions, and ensure that support systems meet deflection limits and structural safety. Avoid cutting or drilling structural building members without project approval.

Mounting and Support

Ladder trays should be mounted using appropriate supports, brackets, and fixing systems to maintain stability and alignment. Supports must be spaced according to manufacturer recommendations and load calculations. Italian ladder trays feature open structures for ventilation, which is ideal for heavy-duty applications and high-temperature environments.

Ensure electrical continuity by properly assembling joints and using copper bonding jumpers where required.

Accessories and Connections

Use compatible elbows, junctions, and covers to maintain modularity and protect cables from dust, moisture, and mechanical impacts. Covers should match the tray material and be installed securely to prevent deformation while allowing proper ventilation. Thermal expansion should be accommodated using cross-slotted joints to prevent stress on the trays.

Installation Best Practices

Install trays level and aligned to avoid sagging or misalignment. Maintain clearances from other services and follow routing plans for accessibility. Ensure safe cable placement, avoiding sharp bends or overcrowding.

Conduct periodic inspections during installation to verify structural integrity and compliance with standards.

Compliance and Safety

All installations should comply with European (EN) and international (UL) standards, ensuring mechanical strength, corrosion resistance, and long-term performance. Personnel should be competent and trained in handling and installing cable ladder systems, following health and safety practices. By following these steps, Italian ladder cable trays can be installed efficiently, providing durable, ventilated, and safe cable management for industrial and infrastructure projects.
