In the design preparation stage, it is necessary to clarify the specific requirements and design plan of the cable tray, including structural dimensions, load requirements, installation environment, etc. Designers usually use computer-aided design software for drawing and calculation to ensure the safety and stability of the bridge.

接下来，在材料准备阶段，会根据设计方案中的要求，准备所需的金属材料，包括角钢、槽钢、钢管等。这些材料需要进行选材和采购，确保质量可靠，并满足相关标准和规范的要求。

Next, in the material preparation stage, the required metal materials, including angle steel, channel steel, steel pipes, etc., will be prepared according to the requirements in the design plan. These materials need to be selected and purchased to ensure reliable quality and meet the requirements of relevant standards and specifications.

然后，在加工制作阶段，将进行材料的切割、弯曲、冲孔等加工工艺，确保其尺寸和形状符合设计要求。这些加工工艺通常在的金属加工厂或钣金加工厂进行，通过机械加工或手工操作完成。

Then, during the processing and production stage, the material will undergo processing techniques such as cutting, bending, and punching to ensure that its size and shape meet the design requirements. These processing techniques are usually carried out in professional metal processing factories or sheet metal processing factories, and are completed through mechanical processing or manual operations.

在加工完成后，就可以进行桥架的装配工作。装配过程中，需要根据设计方案中的尺寸和安装要求进行定位、拼接和固定。通常会使用焊接、螺丝连接、榫卯连接等方法进行桥架的组装。

After the processing is completed, the assembly work of the bridge can be carried out. During the assembly process, it is necessary to position, splice, and fix according to the dimensions and installation requirements in the design plan. Usually, welding, screw connection, mortise and tenon connection, and other methods are used to assemble the bridge.

完成桥架的装配后，需要进行检验验收。这一步主要是检查桥架的尺寸、连接件的牢固性、线条的整齐程度等，确保桥架的质量和性。同时，也要检查桥架与电缆的配合是否紧密，避免出现松动或脱落现象。

After completing the assembly of the bridge, inspection and acceptance are required. This step mainly involves checking the size of the bridge, the firmness of the connectors, and the neatness of the lines to ensure the quality and safety of the bridge. At the same time, it is also necessary to check whether the bridge and cable are closely matched to avoid looseness or detachment.

经过检验验收合格后，桥架就可以准备交付使用。在交付过程中，通常需要提供相应的技术文件和安装说明书，以便客户了解桥架的使用方法和注意事项，确保安装和使用的顺利进行。

After passing the inspection and acceptance, the bridge can be ready for delivery and use. During the delivery process, it is usually necessary to provide corresponding technical documents and installation instructions, so that customers can understand the usage methods and precautions of the bridge, and ensure the smooth installation and use.
