Standard ladder-type cable tray

Ladder type cable trays consist of two longitudinal side rails with transverse rungs, designed to support cable loads while providing ventilation and easy access.Construction and Materials

Ladder type cable trays are typically fabricated from steel, aluminum, or stainless steel, with finishes including hot-dip galvanized, powder-coated, or painted surfaces to resist corrosion and meet environmental requirements . The side rails are usually I-beam shaped for structural strength, and the rungs are welded to the side rails to form a rigid framework . Rungs have radiused edges and a minimum cable bearing surface of 7/8 inch to prevent cable damage .

Dimensions and Rung Spacing
  • Rung spacing is commonly 6, 9, or 12 inches on center, with radiused fittings typically using 9-inch spacing measured at the tray center .
  • Tray widths range from 6 to 36 inches, depending on cable volume and installation requirements .
  • Usable load depth is generally 3 to 6 inches, or as specified in project drawings .
  • Standard lengths for straight sections are 10, 12, 20, 24, 25, 30, and 40 feet, with shorter lengths used to facilitate assembly .
Load Capacity and Safety

Each rung must support the cable load with a safety factor of 1.5 and withstand a 200 lb concentrated load when tested according to NEMA VE 1, section 5.4 . The load class, which defines the tray's load-carrying capability for a specific support span, significantly affects design and cost .

Installation and Mounting

Ladder trays can be mounted to floors, walls, ceilings, equipment racks, and cabinets. They are designed to provide mechanical support, strain relief, and smooth cable bends for long cable runs . Modular systems allow easy configuration for new or existing cable routing, and fittings such as bends, tees, elbows, and drop-outs are available to accommodate complex layouts .

Compliance and Standards

Ladder type cable trays comply with ANSI/NFPA 70 (NEC), NEMA VE 1, and relevant ASTM standards including A123, A653, A1011, A1008, and B633 for steel and zinc coatings . These standards ensure structural integrity, electrical safety, and durability under normal operating conditions.

Additional Features
  • Continuous airflow through the ladder design prevents cable overheating .
  • Modular fittings and accessories allow quick assembly and expansion.
  • Available in gray or black finishes to match equipment aesthetics in data centers or industrial environments . These specifications provide a comprehensive framework for selecting, designing, and installing ladder type cable trays in industrial, commercial, and data center applications.
