Answer from Ningbo Changshi: The correct procedure for a winch-based cable pull involves careful planning and a methodical execution to ensure both safety and the integrity of the cable. The key steps are:

• 1. Site & Equipment Preparation: Before you begin, the winch must be securely anchored and leveled in line with the pull. Ensure the pulling line has at least five full wraps on the winch drum to prevent slippage and damage. At the feeding end, the cable drum stands or jacks should be positioned to allow the cable to feed smoothly into the conduit.

• 2. Rigging the Pull: Attach the pulling line to the cable using a properly sized cable pulling grip (or sock). A Swivel must be used between the grip and the pulling line to prevent the cable from twisting under tension. A tension meter is then rigged in-line to provide real-time monitoring of the pulling force.

• 3. Controlled Operation: The winch should be operated smoothly and consistently. Avoid sudden starts or stops that can create dangerous shock loads. Monitor the tension meter at all times to ensure the pulling force remains within the cable manufacturer's specified limits.

• 4. Communication and Safety: Maintain clear communication between the winch operator, the Cable Feeder, and any personnel along the route. Keep all hands and body parts clear of the moving line, and never step over a line under tension. A safe distance should be maintained by all personnel from the winch and the pulling line.

Adhering to this professional procedure minimizes risk and ensures a successful installation.
