Heavy Duct Cable Tray
EHCT Cable Tray Systems
Heavy duty cable tray is a high-strength, heavy-load cable support system made of thickened steel. It features strong rigidity, good stability and high load capacity, widely used for laying large heavy power cables in industrial plants, docks and infrastructure projects.
Total weight of cables per section > 200kg/m
Span > 3m (standard 3m/6m)
Multi-layer stacking and dense large-current power cables
Outdoor/corrosive/high-temperature/high-vibration industrial environment
Code requirement: Safety factor ≥ 1.5
Allowable deflection: ≤ Span L/200 (≤10mm for 2m span)
Safety factor: ≥ 1.5
Example: Heavy-duty pallet with 2m span, 2.5mm steel plate, and 300mm width: Approximately 400–500kg/m
Standard horizontal: 3m (light-duty), 2m (recommended for heavy-duty)
6m long span: Reinforcing ribs/truss structure is required
Vertical installation: ≤1.5m per bracket
Tees/elbows/reducers: Add additional brackets
Industrial/outdoor: Check deflection, bolts, corrosion, and grounding every 3–6 months
Indoor conventional: Once a year
Corrosive areas: Every 1–3 months
