Wall-Mounted Brackets: The Most Cost-Effective Mounting Solution
When cable trays must be routed horizontally along a wall, galvanized angle-steel brackets offer excellent value:
Bracket Spacing: Recommended spacing is 1.5–2 meters; spans exceeding 3 meters require additional anti-sway bracing.
Expansion Bolts: Use M10 specifications for concrete walls; for brick-concrete structures, through-wall threaded rods are recommended.
Slope Adjustment: A drainage slope of 0.5%–1% can be achieved using bracket shims.
Ceiling Suspension: A Flexible Spatial Solution
For scenarios requiring routing over equipment or piping, the combination of suspension rods and cross-arms offers distinct advantages:
Single-Tier Suspension: Use Φ8 fully threaded rods with spacing not exceeding 1.8 meters.
Multi-Tier Arrangement: Maintain a vertical clearance of 300 mm between cable tray tiers.
Vibration Damping: Install rubber pads to absorb vibration in areas subject to oscillation.
Column Support: Key Technology for Long-Span Scenarios
Modular column systems are recommended for open spaces such as workshops:
Base Anchoring: Floor-embedded steel plates must be ≥10 mm thick; vertical deviation of columns must be <3‰.
Span Optimization: With a standard 6-meter span, cable tray deflection is controlled within 1/200 of the span.
Expansion Capacity: Reserve 20% extra column height to facilitate future system expansion.
