Traditionally, long cables such as power and communication cables were omitted.
Alternatively, when pulling in along a trough, etc., a pulling device such as a winch is installed at the front end of the pipe (hereinafter referred to as the pipe), and a caterpillar type drive device is installed in a manhole, etc. in the middle of the pipe. A method is used in which a long body (hereinafter referred to as a cable) is pulled by a pulling machine and a drive device.

However, the caterpillar type drive device is a large device, and it is difficult to install it in a narrow manhole. In addition, the caterpillar type drive device is a device that continuously pulls the cable while holding it between a pair of caterpillars, so if it is installed at multiple locations in the pipeline, the drive device cannot be pulled in at any one location. Changes in speed can cause excessive tension or slack in the cable. These problems were accumulated without being corrected along the way, causing problems such as cables breaking or clogging in conduits, making it impossible to continue the installation work.
