Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a railway cable laying and paying-out device. Background Art

[0002] Railway cables are special wires used on railways. Existing long-distance transmission cables are all wound on cable drums. During the cable laying process, the cables on the cable drums need to be pulled out. To pull out the cables, the cable drums need to be supported. The cable drums need to be supported in a suspended state. However, when laying cables on both sides of the railway track, it is difficult to use large equipment to support the cables, and it is not convenient to support and rotate the cable drums. Therefore, the difficulty of laying railway cables is increased. For this reason, we propose a railway cable laying and wire-laying device. Utility Model Content
