2. Description of the Related Art In a boiler or other various plants, as shown in FIG. 12, control signals for control equipment and instrumentation signals for instrumentation devices provided in a main plant device 1 are sent to an operation room side 2. To communicate with each other, a large number of control cables are arranged so as to surround the main plant equipment 1.

For this reason, a main cable tray 3 for collectively supporting a large number of control cables is arranged around the plant main device 1 and between the plant and the operation room side 2. The cable tray 3 is bent in the vertical and horizontal directions while avoiding structural members such as the floor of the building supporting the main plant equipment 1, supporting pillars, or other equipment and devices, and is shown in FIGS. 13 and 14. Building 4
It is adapted to be supported by a gantry 5 provided at the same location.

For example, in a boiler or the like, thousands of wires for control are required, and these wires have 2 to 32 cores.
A cable tray 3 in the form of a groove having a width capable of aligning and supporting the control cables 7 each having a core-like wire so as not to overlap each other is arranged. In the case of FIG. 13 and FIG. 14, the cable trays 3 are configured in multiple stages, and the uppermost cable tray 3a is loaded with a large-diameter power (power feeding) cable 6 for feeding power, and the cables in the lower stage. A control cable 7 having a relatively small diameter is loaded in the tray 3b, and a control cable 7 for sending a signal for instrumentation is loaded in the lower cable tray 3c.

When the control cable 7 is laid on the cable tray 3, for example, the cable tray 3 is operated from the operation room side 2.
Connect the control cable 7 pulled inside to the cable tray 3
The worker is manually installed by gradually moving the worker into the inside while moving on a scaffold (not shown) provided along the line.

[0006]

However, in the above-mentioned conventional method, all the work of laying the control cable 7 on the cable tray 3 is performed manually by the worker, and therefore the bent cable tray is used. It is necessary to arrange a large number of workers in order to lay the control cable 7 on the cable 3, and the work efficiency is very poor. Moreover, the cable tray 3 is a structural member such as a building floor or a supporting column, or other device equipment. Since it is often arranged in a bent manner in the vertical and horizontal directions avoiding the above, it is necessary for the worker to send in the control cable 7 and lay it while passing the narrow space in a narrow space. There was a problem that it was difficult and heavy labor, and that it took a long time to work and the construction period was extended.

The present invention has been made in view of the above circumstances, and an object thereof is to facilitate the work of laying a control cable on a bent cable tray and to improve the efficiency.
