[Chai Jin cable tray to recommend the star product - the choice of bridge] bridge 1.1 in the engineering design, the bridge shall be arranged based on a comprehensive comparison of economic rationality, technical feasibility, operational security, and other factors to determine the best cable tray program, but also to fully meet the construction, installation, maintenance, repair and cabling requirements. 1.2 bridge height from ground level when the laying of generally not less than 2.5m tray for cable tray, 1.8m from the ground, the following section should be added to the metal cover to protect the vertical laying of cable tray installation, but laying in electrical rooms excluded. Horizontal cable tray laid in the device or on the mezzanine troops Road and less than 2.5m, should take measures to protect the ground. [Chai Jin cable tray to recommend the star product - the carrying capacity of the bridge] is usually cable tray cable tray load characteristic curve represents. As can be seen by the load curves, the size of the cable tray loading capacity is the amount of a bridge away from the relevant specifications and support. The same distance between the support and the amount of deformation corresponding to the convex bending. Side height of the bridge carrying capacity, the height of a small bridge carrying capacity is small. In addition, when the load capacity planning, is the same, for the same cable tray specifications. Small distance from the support than the support of a large amount of bending deformation is small. Under normal circumstances every l.5 ~ 2.0m cable tray installation of a set of brace.
