1. The load level of the straight tray type bridge should be accurately selected. When estimating the weight of cables, it is advisable to consider the weight of the reserved margin; Temporary additional concentrated loads or other special loads that need to be considered for construction and inspection.

2.應編制鋁合金橋架系統所需托盤、梯架縱貫、彎通、支吊架及主要附件的規格和數目的明細表，并注明其荷載等級和表面防腐處理等技術要求。

2. A detailed list of the specifications and quantities of trays, ladder frames, vertical runs, bends, supports, hangers, and main accessories required for the aluminum alloy bridge system should be prepared, and their load levels and surface anti-corrosion treatment technical requirements should be indicated.

3.系統平面布置圖中應標出鋁合金橋架的路徑走向，托盤或梯架的規格、層數，各類彎通的位置，變寬、變高板及伸縮板的設置點，支吊架的配置及相關尺寸。

3. The system layout plan should indicate the path direction of the aluminum alloy cable tray, the specifications and layers of the tray or ladder, the positions of various bends, the setting points of the widened, raised, and expansion plates, the configuration and related dimensions of the supports and hangers.

4.系統設計應保證橋架能知足工程所需敷設電纜的總量。

4. The system design should ensure that the bridge can meet the total amount of cables required for the project.

5.系統設計時應優先選用尺度系列產品，對工程所需的非尺度件應給出詳圖及技術說明。

5. When designing the system, priority should be given to selecting scale series products, and detailed drawings and technical descriptions should be provided for non scale components required by the project.

6.系統剖面圖中應標出鋁合金橋架的層間間距、支吊架的層間標高、路徑走向的標高變動、支吊架的安裝方式等。

6. The system profile should indicate the interlayer spacing of the aluminum alloy bridge, the interlayer elevation of the supports and hangers, the elevation changes in the path direction, and the installation method of the supports and hangers.
