[0002] During the construction of cables and optical cables, we often encounter the problem of cable trenches that cannot be excavated due to obstacles caused by ground structures. At this time, we need to use a trenchless directional drill to pass the cable protective tube directly from underground. When using a trenchless directional drill, it is necessary to install a drill rod at every interval and gradually extend it forward to achieve long-distance protective tube dragging and dropping. Although each drill rod is only 3-4.8 meters long and has a diameter ranging from 60 to 118, the drill rod is a solid structure and is very heavy. During the loading and unloading process of the drill rod, manual loading and unloading is very laborious, and sometimes it will get stuck, affecting the construction progress.
