Description

Technical Field

[0002] Submarine cables are also referred to as submarine cables, which generally refer to submarine communication cables and submarine power cables. Submarine cable projects are generally recognized as relatively complex large-scale projects. In this project, cable laying machines are more commonly used to provide traction and braking force for submarine cables. They are indispensable special equipment in the process of laying submarine cables. This type of cable laying machine often leads to a larger size as the required traction force increases. In some fixed and open places, the use of this more mature cable laying machine can stably and efficiently complete the laying of submarine cables.

[0003] However, when installing submarine cables in temporary and limited-space locations, such as in land-based cable trenches, the use of traditional cable tractors often faces problems such as transportation difficulties and inability to install. In addition, as the submarine cable is pulled over long distances, the forward path of the submarine cable is unstable, and long-term scratches and friction will damage the outer structure of the submarine cable and shorten the service life of the submarine cable. Manual auxiliary adjustments are also required, which makes the onshore pulling time of the submarine cable longer, seriously affecting the efficiency and cost of the submarine cable pulling construction.
