300mm Ladder Tray

300mm ladder tray

The Marine Cable Ladder is a specialized, heavy-duty cable support system designed for the harsh, corrosive, and demanding environments of the maritime and offshore industries. Unlike standard industrial cable trays, it is engineered to withstand constant vibration, moisture, salt spray (salt fog), extreme temperatures, and mechanical stress encountered on ships, offshore platforms, docks, and in coastal installations.

As a leading manufacturer and supplier of cable trays, Bending offers high-quality cable tray solutions to meet the needs of various harsh environments. Products are made from common materials such as steel, aluminum alloy, or fiberglass.

300mm ladder tray Characteristics & Features

About Material

• Hot-Dip Galvanized Steel (HDG): Most common. Offers excellent strength and corrosion resistance at a lower cost.
• Aluminum-Magnesium Alloy (Marine-grade Aluminum): Lightweight, offers superior corrosion resistance in saltwater environments without painting, and is non-magnetic (crucial for certain vessel types like minesweepers).
• Stainless Steel: Used in areas of extreme corrosion or for specific chemical resistance. Often used for fittings and rungs.

About Feature

• Open Ladder Design:It provides maximum ventilation and preventing heat buildup from cables, easy accessibility for cable installation/inspection, and excellent heat dissipation.
• Corrosion Protection: Beyond the base anti-corrosion material, additional protection includes polyester powder coatings, zinc plating, or anodizing.
• Load Capacity & Strength: Engineered to hold significant weight (hundreds of pounds per linear foot) to support dense bundles of heavy copper and fiber cables over long spans.

300mm ladder tray Structure

• Side Rails: The longitudinal beams that bear the load. Depth (height) determines stiffness and load capacity.
• Rungs: Cross-bars that provide cable support and retention spacing. Standard spacing is typically 225mm and 300mm.
• Fittings: A variety of components to create a complete pathway system:
• Straight Sections: Customizable.
• Tees and Crosses: For intersections.
• Reducers: To transition between different widths.
• Drops & Standoffs: To connect from the overhead ladder to cabinets/racks.

Marine Cable Ladder Advantages

• High Load-Bearing Capacity: Ideal for heavy-duty power cables (e.g., HV/MV) and dense cable bundles.
• Long Support Spans: Fewer supports required compared to solid-bottom trays, reducing installation time and cost.
• Future-Proofing: Easy to add, remove, or reroute cables to accommodate system expansions or changes.
• Safety: Provides organized, elevated routing, protecting cables from ground hazards (water, physical damage). Proper grounding creates a continuous earth path.
• Cost-Effective: Lower initial material cost than some alternatives and significant savings in long-term maintenance and modification.
