Vertical shaft cable tray support arms are designed to securely support vertical cable tray runs, typically using threaded rods, coupler plates, or strut mounts, and are manufactured to meet industry standards for load, material, and corrosion resistance.

Design and Function

Vertical support arms are engineered to support vertical cable tray runs, ensuring safe routing of cables in shafts or risers. They are commonly used in industrial and commercial installations where cable trays must transition vertically between floors or levels . These supports are not intended for human load-bearing but are designed to handle the mechanical load of cables and trays .

Mounting Methods

• Threaded Rods: Vertical support arms are often suspended using threaded rods, which allow height adjustment and secure attachment to ceilings or structural elements .
• Coupler Plates: Supports can be bolted directly onto coupler plates at splice points for continuous vertical runs .
• Field-Drilled Side Rails: Some designs allow bolting anywhere along the cable tray by drilling side rails on-site, providing flexibility in installation .
• Strut Mounts and Wall Brackets: Certain vertical supports integrate with strut channels or wall mount brackets for easy assembly and alignment .

Materials and Finish

• Steel or Stainless Steel: Most vertical support arms are made from steel or stainless steel for strength and durability .
• Electro-Galvanized or Galvanized Coatings: Corrosion protection is provided through electro-galvanization or other galvanic coatings, suitable for indoor and outdoor environments .
• Surface Treatments: Additional galvanization or powder coating may be applied depending on environmental exposure and project requirements .

Standards and Compliance

• BS EN 61537: Cable tray and support systems are manufactured in accordance with this standard, ensuring mechanical and electrical safety .
• DIN EN 61537: European standard for cable support systems, covering material, load capacity, and installation requirements .
• UL and CE Certifications: Many products are certified to UL or CE standards, confirming compliance with safety and quality regulations .

Dimensions and Load Considerations

• Dimensions vary by manufacturer and load requirements; typical specifications include arm length, width, and thickness to accommodate cable tray sizes and weight .
• Load capacity depends on the material, mounting method, and spacing of supports. It is essential to consult manufacturer datasheets for exact load ratings and spacing recommendations .

Installation Notes

• Supports should be installed by qualified personnel familiar with electrical installation practices .
• Ensure proper alignment and secure fastening to prevent tray sagging or cable damage.
• Verify compatibility with the cable tray system being used, as components are designed to function as an integrated system . Vertical shaft cable tray support arms provide a reliable solution for vertical cable management, combining flexibility, strength, and compliance with industry standards to ensure safe and efficient cable routing in multi-level installations.
