Cable tray cut at 70 degrees

A 70-degree cut in a cable tray can be safely achieved using a band saw, circular saw, or angle grinder with proper precautions and PPE.Cutting TechniquesWhen making a 70-degree cut in a cable tray, it is important to select the right tool based on the tray material and thickness. Commonly recommended tools include:Band saws: Ideal for low-height, thin metal trays, providing accurate cuts with minimal debris and noise. Ensure the blade is suitable for the material and thickness .Circular saws: Suitable for light channels and ladders. Use a guarded saw with a chip collector to reduce contamination and a blade brake for safety .Angle grinders: Offer flexibility for angled cuts but produce more splatter and require careful handling with both hands. Protect surrounding materials from sparks and avoid overheating . Cutting with torches is not recommended, as it can damage surface treatments and weaken the material .Safety ConsiderationsAlways wear Kevlar gloves, eye protection, headgear, and appropriate footwear when handling and cutting trays .Ensure the work area is clear of flammable materials and that sparks or debris do not damage nearby equipment .Avoid mixing cutting blades between different metals (e.g., stainless steel and carbon steel) to prevent galvanic corrosion .Material and Angle ConsiderationsMeasure and mark the 70-degree angle accurately before cutting. Using a protractor or angle guide can help maintain precision.For modular or bolted systems, ensure that the cut does not compromise the structural integrity of the tray. Reinforce or support the cut ends if necessary .After cutting, deburr edges to prevent injury and ensure smooth cable installation .Installation TipsWhen designing angled runs in cable trays, consider the gradual bend to avoid sharp turns that can stress cables .Use appropriate fittings or splice plates to maintain mechanical support and alignment after cutting .Verify that the cut tray section complies with load and span requirements to maintain safety and reliability . By following these guidelines, a 70-degree cut can be executed safely and accurately, ensuring both the structural integrity of the cable tray and the safety of personnel during installation.
