The gasoline-powered optical cable tractor is primarily suitable for long-distance traction within pipelines and tunnels. The crawler-type tractor, which relies on dual crawlers to grip the optical cable, boasts strong traction and anti-slip capabilities, making it ideal for complex terrains. Additionally, there are specialized models, such as the elevating tractor used for overhead laying. Their common advantage is that they are self-powered and flexible in movement, making them highly suitable for construction environments without mains electricity supply in the wild.
