What is the best approach to calculate the pulling tension of a whole run?

Calculating the pulling tension of a whole run by considering each section at a time is the best approach because it provides a detailed understanding of the varying conditions that can affect tension throughout the entire length of the run. Each section may have different factors such as bends, elevation changes, friction characteristics, and the type of materials being pulled. By analyzing each segment individually, you can accurately account for these variations, ensuring that the calculated tension reflects real-world challenges encountered during the pull.

This method allows for adjustments based on specific conditions that can occur in different sections, leading to a more precise assessment of the total pulling tension. It mitigates the risk of underestimating or overestimating tension, which can lead to equipment failure or operational difficulties.

In contrast, estimating based on average weights or past pulls might overlook critical variations in the current scenario, while using a single pulling force for the entire run fails to capture the complexities involved in different segments of the pull. Therefore, breaking it down into manageable sections ensures a thorough evaluation, facilitating better planning and execution of the pulling process.
