Specifications of cable tray support clamps for factory buildings

Cable tray support clamps for industrial settings are designed to provide rigid, safe, and durable support for cable trays, with materials, load ratings, and installation methods conforming to IEC 61537 and other industrial standards. Types of Cable Tray Support ClampsHold-Down ClampsUsed to secure cable trays to beams or C-channels. Heavy-duty versions can attach trays to bridges or structural steel without drilling, using set screws.

Materials: copper alloy, steel, or stainless steel; tin plating may be applied for corrosion resistance. Load capacity: typically up to 400 lbs for single clamps, depending on design and beam size.

Grounding Clamps

Provide electrical continuity and grounding for cable trays. Constructed from copper alloy with durium bolts, nuts, and washers. Tin plating is optional for enhanced corrosion protection.

C-ClampsSupport hanger rods on I-beams, wide flange beams, or angles. Supplied in unfinished iron or zinc-plated steel. Maximum allowable load: 300 lbs for standard wide-flanged clamps.

Channel Clamp Assemblies

Designed for American Standard channels with flange widths up to 3-1/4". Can include swivel joints for flexible alignment. Maximum allowable load: 500 lbs.

Materials and Corrosion Protection

Common materials: steel, stainless steel, and copper alloys. Surface treatments: galvanization, tin plating, or zinc plating to resist corrosion in industrial environments. Selection depends on ambient conditions, exposure to chemicals, moisture, or mechanical stress.

Installation Considerations

Clamps must be compatible with the tray type (ladder, solid-bottom, or mesh). Support elements (brackets, suspended supports, or center suspensions) connect trays to ceilings, walls, or floors. Mounting hardware is often included, and field drilling may be required for certain heavy-duty clamps.

Proper spacing and alignment are critical to maintain structural integrity and prevent sagging. Standards and ComplianceIEC 61537: International standard for metal cable tray systems, ensuring mechanical strength, electrical safety, and durability.

DIN E

N 61537: Defines cable support systems, including trays, fittings, and support elements, with requirements for industrial environments. Compliance ensures safe load handling, compatibility across installations, and reduced risk of electrical hazards.

Summary

For factory buildings, cable tray support clamps should be selected based on: Load capacity (400–500 lbs for heavy-duty clamps)Material and corrosion resistance (steel, stainless steel, copper alloy, plating)Compatibility with tray type and structural elementsCompliance with IEC 61537 and DIN EN 61537 standards Using the correct clamps ensures safe, durable, and efficient cable management in industrial environments, minimizing maintenance and installation risks.
