Underground shovel loader plays an important role in operations in narrow spaces such as underground mines and tunnels. It can improve work efficiency, reduce labor costs, and ensure work safety. When the shovel loader is operating, cables are required to play an important role in connecting power and control signals in the underground shovel loader to ensure that the shovel loader can operate normally and accurately according to the operator's instructions.

[0003] When the existing scraper cables are in use, most of them are damaged by the internal wire core due to the crushing or squeezing of external objects.

In addition, when the existing scraper cables are in use, the outer skin may be worn due to friction between the outer skin and the work site, thereby affecting the use of the cable. Therefore, technical improvements are urgently needed. Utility Model Content
