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(yīng)編制鋁合金橋架系統(tǒng)所需托盤、梯架縱貫、彎通、支吊架及主要附件的規(guī)格和數(shù)目的明細(xì)表，并注明其荷載等級和表面防腐處理等技術(shù)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(tǒng)平面布置圖中應(yīng)標(biāo)出鋁合金橋架的路徑走向，托盤或梯架的規(guī)格、層數(shù)，各類彎通的位置，變寬、變高板及伸縮板的設(shè)置點，支吊架的配置及相關(guān)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(tǒng)設(shè)計應(yīng)保證橋架能知足工程所需敷設(shè)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(tǒng)設(shè)計時應(yīng)優(yōu)先選用尺度系列產(chǎn)品，對工程所需的非尺度件應(yīng)給出詳圖及技術(shù)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(tǒng)剖面圖中應(yīng)標(biāo)出鋁合金橋架的層間間距、支吊架的層間標(biāo)高、路徑走向的標(biāo)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.
