How to Test the Strength of Tarred Bankline Safely?

April 5, 2026

Quick Answer

Testing the strength of tarred bankline safely involves a controlled pull test while protecting the surrounding area from potential damage.

Preparing for the Test

To safely test the strength of tarred bankline, select a test area with sufficient clearance from other objects and obstacles. Ensure the bankline is properly positioned and secured at both ends using suitable anchors or blocks to prevent slippage during the test.

Conducting the Pull Test

Begin the pull test by attaching a calibrated load cell or a reliable weight-measuring device to one end of the bankline. Gradually apply a steady and controlled force to the bankline, typically starting with a load of around 10-20 kilograms (22-44 pounds) and increasing by 5-10 kilograms (11-22 pounds) every minute until the bankline fails. Record the maximum load at failure and calculate the bankline’s strength-to-weight ratio for comparison with industry standards or manufacturer specifications.

Analyzing the Results

After conducting the pull test, inspect the failed bankline for signs of structural failure, such as thread breakage, core splitting, or tar cracking. Analyze the data collected during the test to determine the bankline’s tensile strength, which can be used to assess its suitability for specific applications or to identify areas for improvement in manufacturing processes.
