[0002] As the main structure of the catenary support device, the boom is an important part of the catenary. In the past, the boom pre-assembly process was divided into five steps: feeding, length determination, cutting, marking, and blanking;

[0003] Feeding was manual feeding. Two people were required to lift and place it into the tooling. There were many people, and two people needed to cooperate during the handling process, which was prone to errors and cause injuries;

[0004] Length determination was that personnel put the workpiece into the tooling, measured and marked lines. Repeated operations by personnel were likely to cause large measurement errors, resulting in poor consistency of finished products;

[0005] Marking was manual marking, and the consistency was poor;

[0006] Currently, there are many personnel involved in the boom pre-assembly process. Each step is independent and manual operation. The equipment occupies a large area, and the product consistency is poor. During the boom pre-assembly process, there is a lack of a device that integrates all steps.
