动载荷是指在电缆桥架设备和保护过程中施工和维修人员的重量。对于轻型电缆桥架，一般不考虑动载荷，即电缆桥架上不允许人站立。假设需要考虑站立的人，则应适当减小跨度。

Dynamic load refers to the weight of construction and maintenance personnel in the process of cable bridge equipment and protection. For light cable tray, dynamic load is generally not considered, that is, people are not allowed to stand on the cable tray. Assuming that people standing need to be considered, the span should be appropriately reduced.

静载荷是指电缆桥架中敷设的每根电缆的种类、数量、外径分量/单位长度，根据电缆敷设的不同路线计算得出。附加荷载仅指室外区域由冰、雪、风和电磁力组成的荷载。它与设备现场的自然天气条件和带电体的性质有关。应根据规划中的各种情况进行计算。

Static load refers to the type, quantity, outer diameter component / unit length of each cable laid in the cable tray, which is calculated according to different routes of cable laying. The additional load only refers to the load composed of ice, snow, wind and electromagnetic force in the outdoor area. It is related to the natural weather conditions of the equipment site and the nature of the charged body. The calculation shall be carried out according to various situations in the planning.

检查电缆桥架设备的平衡缸及其油润滑系统油路的动作状态，检查接头号。电缆桥架设备的滑块与导轨反复摩擦，应进行必要的调整以纠正。检查接头各部位及管路等的平整度，保证运转。

Check the action status of the balance cylinder of the cable tray equipment and the oil circuit of its oil lubrication system, and check the joint number. If the sliding block of cable tray equipment rubs repeatedly with the guide rail, necessary adjustment shall be made to correct it. Check the flatness of each part of the joint and pipeline to ensure operation.

定期使电缆桥架设备的齿轮部分光滑：齿轮传动箱和内部零件因频繁操作而损坏的可能性更大，松动的可能性更大。当这些部位出现噪音时，可以先进行平滑处理，然后根据振动情况，检查系统间注油点的出油量和压力，并进行适当的调整。

Regularly make the gear part of the cable tray equipment smooth: the gearbox and internal parts are more likely to be damaged and loose due to frequent operation. When there is a noise in the oil injection room, check the oil injection points according to the conditions of the oil injection room, and then deal with them properly.

此外低压电缆与控制电缆共用同一托盘或梯架时，应选用中间有隔板的托盘或梯架；在托盘、梯架分支、引上、引下处应设适当的弯通；因受空间条件限制不便装设弯通或有特殊要求时，可选用软连接板，铰接板；伸缩缝应设置伸缩板；连接两段不同宽度或高度的托盘、梯架可配置变宽或变高板。但在施工中，支、吊架和桥架的选择应依设计或工程布置条件选择。

In addition, when the low-voltage cable and control cable share the same tray or ladder, the tray or ladder with partition in the middle shall be selected; Proper bends shall be set at the branches, leading up and leading down of trays and ladders; Due to the limitation of space conditions, flexible connecting plate and hinged plate can be selected when it is not easy to install elbow or there are special requirements; Expansion joints shall be provided with expansion plates; Connecting two sections of trays and ladders with different widths or heights can be configured with widening or heightening plates. However, during construction, the selection of supports, hangers and bridges shall be based on the design or engineering layout conditions.

济南电缆桥架安装选择需屏蔽电气干扰的电缆回路，有腐蚀的场所、易燃粉尘场所，应选用无盖无孔封闭型托盘，当需要因地制宜的场所，宜选用组装式托盘或有孔托盘及梯架；在容易积灰和其它需遮盖的环境或户外场所，宜带有盖板。更多相关内容来网站 www.comprepyme.com关注吧！

For the installation of cable bridge in Jinan, the cable circuit that needs to shield electrical interference shall be selected. In places with corrosion and flammable dust, the closed tray without cover and hole shall be selected. When it is necessary to adjust measures to local conditions, the assembled tray or perforated tray and ladder shall be selected; Cover plate should be provided in the environment or outdoor places where dust is easy to accumulate and other places need to be covered.
