Professional Answer: Manually pulling heavy cables is a physically demanding task that poses significant ergonomic risks. The most common hazards include musculoskeletal injuries to the back, shoulders, and arms. These often result from:

• Heavy Pulling Force: Exerting too much manual effort, especially with large-gauge wire, can cause strain.

• Repetitive Motions: Pulling over long distances or through multiple bends can lead to repetitive stress injuries.

• Awkward Postures: Working in confined spaces, at heights, or in bent-over positions puts undue stress on the body. To prevent these injuries, we at Ningbo Changshi highly recommend using mechanical pulling equipment, such as tension stringing machines and pulling winches. These tools reduce manual effort to almost zero, ensuring a safe and efficient pull.
