Busline Trapezoidal Cable Tray Support Installation

Busline Trapezoidal Cable Tray Support Installation

Trapeze cable tray supports provide a secure, adjustable method to suspend busline and cable trays using threaded rods and pre-galvanized steel channels.OverviewTrapeze supports are widely used to suspend cable trays and busbars from ceilings or structural elements. They consist of a slotted support channel (strut type) and threaded rods that allow height adjustment and secure attachment of cable trays. Materials are typically pre-galvanized steel, stainless steel, or painted steel for corrosion resistance, suitable for indoor or outdoor applications .Components RequiredTrapeze support channel: Slotted deep channel with uniform slots for threaded rod attachment, sized to match the cable tray width .Threaded rods: Typically M10 or M12, used to suspend the trapeze from the ceiling or structural support .Tabs or clamps: Flat tabs or hold-down clamps secure the cable tray to the trapeze .Fasteners: Nuts, washers, and locking hardware to secure rods and tabs in place.Installation StepsPrepare the threaded rods: Cut rods to the required length based on the desired height of the cable tray.Install ceiling anchors: Secure the threaded rods to the ceiling or structural support using appropriate anchors for the substrate (concrete, steel, or other materials), .Attach trapeze support channel: Slide the trapeze channel onto the threaded rods. Ensure the slots align with the rod positions for proper adjustment .Position the cable tray: Place the cable tray onto the trapeze support. For systems like KwikRail, insert a flat-head screwdriver into the tab slots, open the tabs, and position the tray .Secure the tray: Close the tabs or use hold-down clamps to lock the cable tray to the trapeze support. Tighten all nuts and washers to ensure stability .Final adjustment: Verify that the tray is level and properly aligned. Ensure all hardware is tightened and the system can support the intended load.ConsiderationsLoad rating: Ensure the trapeze support and threaded rods are rated for the weight of the cable tray and cables .Corrosion protection: Use galvanized or stainless steel components in corrosive environments .Spacing: Follow manufacturer guidelines for spacing between trapeze supports to prevent sagging.Seismic or dynamic loads: For areas prone to seismic activity, use specialized seismic-rated support systems . Using trapeze supports ensures a flexible, strong, and adjustable installation for busline and cable trays, providing both safety and ease of maintenance .
