For heavy-duty applications involving large, heavy, or long-distance cable pulls, selecting the right Cable pulling machine is critical. Key technical specifications and features to consider include:

• Maximum Pulling Force (kN or lbs): This is the single most important specification. The machine must have a maximum continuous pulling force significantly higher than the calculated maximum tension required for the cable pull, factoring in cable weight, length, conduit friction, and number of bends.

• Continuous Pulling Force: The force the machine can sustain over extended periods without overheating or performance degradation, crucial for very long pulls.

• Pulling Speed (m/min or ft/min): Both maximum speed and variable speed control are important. High speeds can accelerate projects, but the ability to precisely control speed (even very slowly) is essential for delicate cables or navigating complex pathways.

• Drum/Capstan/Bullwheel Design:

  • Drum Pullers: For direct winding of the pulling rope, consider drum diameter, capacity (length and diameter of rope), and level winding mechanism for neat and safe spooling.

  • Capstan/Bullwheel Pullers: For continuous pulling with controlled tension (often releasing rope at the back), consider the number and diameter of grooves, and the lining material (e.g., polyurethane) for grip and cable protection.

• Engine Power (HP or kW) & Fuel Efficiency: A powerful, reliable engine (diesel is common) is essential for sustained heavy pulls. Look for modern engines with good fuel efficiency and lower emissions.

• Hydraulic System Quality: A robust, closed-loop hydraulic system ensures smooth, precise, and consistent power delivery, which is vital for maintaining controlled tension and speed.

• Control System & Data Feedback: Digital control panels with real-time readouts of pulling force, speed, and length pulled are essential. Features like automatic tension limiting and data logging enhance control, safety, and project documentation.

• Mobility & Transport: For heavy-duty machines, consider whether it's a trailer-mounted unit (for highway towing), a self-propelled tracked machine (for off-road mobility), or a skid-mounted unit (for fixed installations).

• Safety Features: Overload protection, emergency stop systems, fail-safe braking, and robust guarding are non-negotiable.
