回転させることが難しい欠点があった。For example, the applicant proposed a suspension line with multiple cable insertion spaces so that other communication cables could be added to the existing communication cables as the number of subscribers increased (Japanese Patent Application No. 1983- 113945). In addition, in order to install a new cable by pushing it into this suspension wire, we proposed a method for laying the cable by suspending it from the suspension cord so that it can run freely and guiding the new cable into the cable insertion space while pushing the entrance of the cable insertion space wide. (Special application 15206/1986)
However, if the cable insertion space of the hanging cord is linear, the cable can be laid without any trouble using the above-mentioned installation method, but if the cable insertion space is spiral around the axis of the hanging cord, then the cable can be laid without any problem. (When installing the suspension wire, it is better to twist it two to three times in one span to prevent the cable from coming out from the cable insertion space.) It is necessary to rotate Ic. However, with the conventionally proposed laying means, there is a drawback that it is difficult to rotate the cable supply means to the hanger 9 of the hanging wire while maintaining the weight balance.

- To provide a cable installation system that allows a new cable to be laid in an empty cable insertion space spirally extending around the axis of a new cable without rotation.

できる。When one span of the cable 20' has been laid, remove the entire device from the suspension line and move it to the next cable. The entire frame may be pulled from the ground by mounting a battery-powered motor on the device to rotate rollers or caterpillars that suspend the entire device in contact with the suspension line, so that the entire device can move by itself. 0′=! However, in the above embodiment, the cable supply means 24 is mounted on the suspension line 12, but it may be installed on the ground. The cable can be laid smoothly in the extended cable insertion space, and since there is no need to rotate the heavy cable supply means to the same height as the hanging line during installation, the work can be done safely without losing balance on the hanging line. It can be carried out.
