[0006] For this reason, the loss time of moving or waiting is long, and the effect on the construction efficiency is large, which is uneconomical. Further, if the movement of the heavy equipment is congested, there is a high possibility that the worker and the heavy equipment and the heavy equipment will come into contact with each other, and there is also a safety problem.
