Answer: When purchasing a Cable Pulling Winch, it's crucial to evaluate several key features to ensure it meets your project's needs. Look for maximum pulling capacity (in kN or tons), rope speed (in m/min), and power source (such as gasoline, diesel, or electric). Modern winches also include advanced features like a limiting pulling force to prevent cable damage, a regular winding system for neat rope management, and a robust hydraulic working system for smooth, powerful operation. Our equipment at Ningbo Changshi is designed with these specifications in mind, providing the reliability and efficiency required for demanding power line projects.
