Drilling holes inside the cable tray

Drilling holes inside the cable tray

Holes in cable trays are typically drilled using a drill or hydraulic punching machine, with templates or splice plates to ensure accurate placement.Tools and EquipmentTo drill holes in cable trays, you will need:Drilling machine or hydraulic punching machine for structural steel or aluminum trays .Drill bits appropriate for the tray material (steel, aluminum, or fiber-reinforced plastic), .Templates or splice plates to mark hole positions accurately .Debris cleaning tools to remove metal shavings after drilling .Hole Placement and MethodMarking the Position: Use a splice plate or a drill jig as a template to locate the hole positions. This ensures that holes for splice plates or dropouts are aligned correctly .Field Drilling: For field-cut trays, drill holes after cutting to length. Ensure that splice plates are placed on the outside of the tray, with bolt heads on the inside unless otherwise specified .Support Considerations: Avoid placing splice plate holes directly over support joints. Position them between supports or at quarter points to maintain structural integrity .Hole Sizes: Common hole sizes include 7/16” for solid bottom trays and 5/16” for dropouts, but always follow manufacturer specifications .Best PracticesUse proper safety equipment such as gloves and eye protection when drilling .Ensure accurate measurements to prevent misalignment of splice plates or connectors .Consider thermal expansion: Allow for expansion and contraction in long tray runs by spacing splice plates appropriately .Clean debris after drilling to prevent damage to cables or hardware .SummaryDrilling holes in cable trays is a precise process that requires the right tools, templates, and careful placement. Using splice plates as guides, following manufacturer specifications, and maintaining proper support spacing ensures a safe, structurally sound, and efficient cable tray installation .
