Cable tray clamping plate fixing

Cable tray clamping plates are fixed using clamp plates, bolts, and nuts to secure trays safely and maintain system stability.Types of Clamping Plates and Fixing KitsFixing Kit A: Used for general clamping of straight tray lengths and fittings. It includes a large clamp plate, small clamp plate, M6 nut, and M6 x 20 coach bolt. Materials can be electroplated zinc, Dacromet, or stainless steel .Fixing Kit B: Designed for situations where only one clamp plate is required, such as fixing plates. It includes a small clamp plate, M6 nut, and M6 x 20 coach bolt .Universal Base Fixing Plates: Used to flush mount trays to flat surfaces, providing a 15 mm clearance for uneven surfaces. Available in pre-galvanised steel, Dacromet, or stainless steel .Vertical Wall Brackets and Central Hangers: For vertical mounting or overhead support, compatible with various tray widths and depths, using threaded rods of appropriate diameters .Installation GuidelinesClamp Placement: Position the clamp plate over the tray section or fitting. For straight runs, use two plates (top and bottom) to sandwich the tray edges. For single-plate applications, ensure the plate aligns with the fixing point .Fastening: Use M6 bolts and nuts (or manufacturer-specified sizes) to secure the clamp plate. Tighten bolts with a spanner or torque wrench to ensure firm, vibration-resistant connections .Orientation: Always pass screws or bolts through the inner side of the tray rail and secure with nuts on the outer side to prevent cable damage .Joint Plates: For wider trays (≥400 mm), use a joint plate between connectors to prevent transverse bending under load. For trays ≤300 mm, joint plates are optional .Material Selection: Choose clamp plates and fasteners compatible with the environment (e.g., stainless steel for corrosive areas, Dacromet for general industrial use) to ensure durability .Safety and Maintenance ConsiderationsEnsure proper torque on all bolts to prevent loosening due to vibration .Check that clamps do not interfere with cable routing or pinch cables. Integrated beading on joint plates can protect cables .Regularly inspect clamped connections for tightness and corrosion, especially in outdoor or industrial environments .By following these guidelines, cable tray clamping plates can be securely fixed, ensuring system stability, safety, and long-term durability.
