Operating Procedures for Mongolian Cloth Cable Trays

The installation and operation of Mongolian cloth cable trays follow standard cable tray procedures, including preparation, material inspection, safe handling, proper installation, and post-installation verification.

Preparation and Planning

Before installation, review all approved shop drawings to determine tray routes, sizes, and locations. Ensure the installation areas are accessible, clean, and ready for work. Verify that all materials, tools, and equipment comply with project specifications and contract requirements . Conduct a site survey to identify any conditions that may affect installation, such as structural obstacles or unsafe areas .

Material Delivery and Inspection

All cable tray components should be delivered to the site fully identified according to shop and CAD drawings. Inspect materials for damage, discrepancies, or non-conformance. Any unsuitable materials must be removed immediately . Store trays horizontally on a flat surface with timber supports at regular intervals, protecting them from moisture, sunlight, and construction activities .

Installation Procedures

1. Pre-Installation Checks: Verify that all materials, documentation, and tools are correct and approved. Ensure personnel are trained and competent .
2. Fixation and Support: Use threaded hanger rods, nuts, locking washers, and support channels with a galvanized finish. Maintain a minimum 40mm clearance between the tray and supporting structure .
3. Tray Placement: Install trays according to approved drawings, making necessary offsets while maintaining free area for cables. Secure cables using tie wraps, cleats, or metal straps depending on cable size .
4. Alignment and Leveling: Ensure trays are level, straight, and properly aligned. Avoid crossovers and maintain neat, workmanlike installation .

Health and Safety

Follow the manufacturer's safety recommendations and project safety plan. All personnel must attend safety induction and demonstrate competency. Monitor for unsafe conditions and correct them before proceeding . Use appropriate personal protective equipment (PPE) during handling and installation.

Quality Assurance and Documentation

Supervisors and QA/QC inspectors should verify that installation follows approved procedures. Maintain inspection checklists, material verification records (MIR), and work inspection requests (WIR). After installation, provide training and operational instructions to the consultant and site management, ensuring proper system operation .

Post-Installation

• Conduct a final inspection to ensure compliance with specifications and drawings.
• Ensure all cables are securely fixed and the system is free from defects.
• Document all inspections, approvals, and handover procedures for future reference . By following these procedures, Mongolian cloth cable trays can be installed safely, efficiently, and in compliance with project and manufacturer standards.
