Answer from Ningbo Changshi: The power source for a Cable Pulling Winch is a critical factor in its performance, mobility, and application. For professional underground projects, the most common and powerful options are:

• Hydraulic Winches (Diesel/Gasoline): These are the most prevalent type for heavy-duty utility work. They use a diesel or gasoline engine to power a hydraulic pump, which in turn drives a hydraulic motor on the winch drum or bullwheel. This system offers exceptional power-to-weight ratio, precise speed control, and a constant, smooth pulling force. The use of a trailer or truck-mounted unit makes them highly mobile and self-contained.

• Electric Winches: These are ideal for projects with a readily available power supply, such as in substations, vaults, or industrial plants. They are typically quieter, produce no exhaust, and are well-suited for confined spaces where ventilation is limited. While they may require a large power source, modern electric winches can deliver substantial pulling force for specific applications.

We specialize in high-capacity, hydraulic winches that are designed to meet the rigorous demands of underground power line installations, providing the reliability and performance required on-site.
