Description

Technical Field

[0001] The utility model relates to the technical field of deep well cable laying, in particular to a lifting device for improving the efficiency of tunnel cable laying. Background Art

[0002] During cable laying, due to the reel's width and the order of the cables, the cable often oscillates back and forth during release, causing the first cable pulley to tip over as the cable emerges from the reel. Therefore, additional construction personnel must be deployed to this location to straighten the tilted pulley. Furthermore, during this process, the personnel must simultaneously support the weight of the cable while simultaneously straightening the tilted pulley and continuing to use it. This can easily lead to personal safety issues during the pulling process, posing a potential safety hazard.
