How to make elbows for PVC cable trays
Creating a 90-degree elbow in an electrical cable tray, often called a "fabricated" or "mitered" bend, involves cutting, bending, and fastening a straight section of tray. The most common method involves creating two 45-degree cuts to form a 90-degree angle. In need to create an elbow that starts at a right angle and that has the ability adopt the angle of the routing of the cable tray. The length of the bottom side (bottom diagonal) after bending the cable tray should be equal to the width of the cable. Determine the angle and required radius size of the elbow, and choose the appropriate elbow type based on these parameters, such as 90 degree elbow, 45 degree elbow, etc. This manual is designed to guide workers through the detailed production process of ladder cable trays, including the manufacture of horizontal elbows, tees, crosses, reducing bends, and vertical bends, with emphasis on precision, safety, and quality control.
