The choice of section bending machine depends on various factors, including the working principle/configuration, drive mechanism, dimensions, control system, and available accessories. Machines can be categorized based on the movement possibilities of the rolls:
Double Pinch Machines: These machines offer the highest flexibility, with independently movable bottom rolls. They excel in both symmetric and asymmetric bending operations, making them ideal for a wide range of applications.
Pyramidal Machines: Featuring fixed bottom rolls and a movable top roll, pyramidal machines are suited for symmetrical bending tasks.
Single Pinch Machines: With only one of the bottom rolls capable of movement, single pinch machines are primarily used for asymmetrical bending applications.

Cable ladders are preferred for supporting high volume or heavy cabling, especially if there are long spans between supports.
Cable trays are typically used for light weight cable support, in addition to instrumentation and tubing.
In most cases, cable ladders are the preferred choice. However, when aesthetics and concerns about radio/electromagnetic interference are important factors, cable trays are more suitable. Cable trays can also be used to protect sensitive cables and piping.
Making bent elbows for cable trays according to the formulas provided in the diagram is for reference only. The data is directly related to the width or height of the cable tray, and calculations can be made based on the formulas given in the diagram.
