Description

Technical Field

[0001] The utility model relates to the technical field of optical cable laying, in particular to a cable car for laying optical cables. Background Art

[0002] Optical cable is composed of a certain number of optical fibers, covered with a sheath, and some are also covered with an outer sheath. It is a communication line used to realize the transmission of optical signals. In order to achieve stable transmission of optical signals, optical cables need to be laid. The main ways of laying optical cables are direct burial laying, overhead laying, pipeline laying and underwater laying. In order to better complete the laying task, cable car is one of the indispensable engineering equipment in the above work.

[0003] Traditional cable trolleys on the market can only transport and lay optical cables. When faced with cable rolls weighing several tons, traditional cable trolleys need to rely on forklifts or cranes for auxiliary loading and unloading.
