Bearing capacity of cable tray

Click:201 Time:2020-01-18 15:13:06

When the cable tray is installed indoors, in order to ensure the straightness, beauty and uniformity of the tray, the horizontal load deformation of the cable tray should be controlled within 4mm generally. We can find the load characteristic curve of the corresponding structure form according to the selected cable tray width and the required horizontal load deformation of the cable tray. If it is not full When enough deformation is required, the side height of the bridge can be increased or the support spacing can be reduced to meet the requirements.

Cable bridge is made of sheet steel, with limited bearing capacity. It will be deformed due to overload of bridge, which will not only affect the beauty of bridge, but also affect the safe operation of cable. Generally, the bearing capacity of cable tray is represented by the load characteristic curve of cable tray. From the load curve, it can be seen that the load capacity is related to the cable tray specification and support distance, corresponding to the same support distance and bending convex deformation. The side height is large and the bearing capacity is large. When the load capacity is the same, the cable tray with the same specification has small bending deformation with small support distance.
