Portable cable trays should be installed with proper support, alignment, and safety measures, and removed carefully to prevent damage or injury.

Planning and Preparation

Before installation, plan the tray route according to the site layout, ensuring adequate clearance, load capacity, and separation from other utilities (Elcon Global) . Select the appropriate tray type—ladder trays for airflow and easy cable entry, perforated trays for lighter loads, or solid-bottom trays for protection against debris (Elcon Global) . Ensure all materials are inspected and stored on dunnage to prevent moisture damage or deformation (Unitray) .

Installation Procedure

1. Support and Mounting: Use brackets, hangers, or steel structures to support trays. Maximum spacing is typically 3 meters for ladder trays and 2 meters for perforated trays to avoid sagging (Paktechpoint) . Supports should handle the tray's load plus future cable additions (Kirac Metal) .
2. Alignment: Align trays straight and level using a laser or string. Install splice plates at ¼ of the gap between supports, avoiding mid-gap placement (Kirac Metal) .
3. Cable Placement: Lay cables flat in horizontal trays, securing them with stainless steel strips or fasteners every 2–3 meters. For vertical trays, fix each cable individually (Paktechpoint) .
4. Safety: Workers should wear gloves and steel-toed footwear during handling. Avoid using trays as lifting points for forklifts or chains (Unitray) .

Portable Tray Removal

1. Unload Carefully: Remove cables first, then detach trays from supports. Use mechanical lifting only if trays are on dunnage or palletized; hand removal is preferred for single sections (Unitray) .
2. Stacking and Storage: Stack trays by type and width, keeping them elevated and ventilated to prevent corrosion or staining (Kirac Metal) . Covers should be used if trays are exposed to mechanical damage or outdoor conditions (Paktechpoint) .
3. Transport: When relocating, avoid bending or crushing tray siderails. Use slings or forklifts carefully, ensuring load stability (Unitray) .

Maintenance Considerations

• Maintain minimum 300 mm clearance above trays for easy cable access (Kirac Metal) .
• Check electrical continuity every 18 meters for safety.
• Inspect supports and fasteners periodically to ensure structural integrity. By following these steps, portable cable trays can be safely installed, maintained, and removed in Belarusian industrial or commercial settings, ensuring both worker safety and system reliability.
