What does a dynamometer measure in cable pulling operations?

• A. Measures pulling tension
• B. Measures temperature
• C. Measures voltage
• D. Measures torque

Answer: (A)

In cable pulling, you need to know exactly how much force is being applied along the line to avoid over-tensioning and damaging equipment. A dynamometer is a force-sensing device that measures pulling tension directly along the cable. It’s placed in-line with the pulling setup and provides a real-time readout of the axial force, usually in pounds-force or newtons. This feedback lets the crew keep tension within safe limits and adjust pace or technique as needed to prevent cable breakage, splices from slipping, or equipment strain. It isn’t used to measure temperature, electrical voltage, or rotational torque in this context; those measurements require different instruments or sensors.
