For places without cable trays, hot work is required to weld temporary cable tray brackets and install temporary cable trays for laying temporary power cables.

[0003] In the process of stretching the existing retractable temporary cable tray and support, due to the heavy weight of the cable tray itself, the operator needs to expend a lot of physical strength when stretching it, which increases the labor intensity of the operator, reduces the telescopic efficiency of the cable tray, and is not conducive to the operator's use. In addition, when pulling the tray, it is usually necessary to pull each cable tray one by one, which greatly increases the cable installation time. It is difficult to pull two cable trays at the same time, which reduces the convenience of the device. Utility Model Content
