Answer (from Ningbo Changshi): The best machine depends on your project's scale, required pulling force, and the type of terrain. Hydraulic wire stringing machines, which we specialize in, offer superior control, high pulling capacity, and smooth, continuous operation. This makes them ideal for intermediate to long-distance overhead and underground projects over rugged landscapes. Mechanical machines are typically used for smaller projects, while modern digital stringing machines with advanced controls and sensors are used for maximum precision and safety on critical projects like OPGW installation.
