Calculate the necessary length of material to form elbows, considering the inner radius and degree of the bend to minimize material stress. The method for producing bridge bend elbows is as follows: Take a 90-degree cable tray bend elbow as an example, and apply the same principles for 45-degree bends accordingly. The length of the bottom side (bottom diagonal) after bending the cable tray should be equal to the width of the cable. 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. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require additional protec eferred to support and protect numerous small.
