The load-bearing test of flexible lifting slings before they are put into storage

Flexible lifting slings, as an important lifting tool, have extensive applications in multiple fields such as industrial production, logistics transportation, and construction. Due to its softness, lightness and portability, flexible lifting slings have been favored by many industries. However, before using flexible lifting slings for lifting operations, they must undergo strict load-bearing tests to ensure their safety and reliability.

Load-bearing tests are an indispensable step before flexible lifting slings are stored in the warehouse. This test aims to examine the load-bearing capacity, wear resistance, corrosion resistance of lifting slings, as well as their performance under different temperatures and environmental conditions. Through the load-bearing test, we can assess the safety margin of the lifting sling in actual use, thereby ensuring that it can meet the expected lifting requirements.

The methods and procedures of load-bearing tests

Preparation stage

Select representative samples of flexible lifting slings.

Determine the loading weight and loading speed of the test.

Prepare the test equipment and measuring tools, such as tensile testing machines, force gauges, etc.

Loading test

Fix the flexible lifting sling on the tensile testing machine and ensure it is in a horizontal position.

Gradually increase the loading weight at a constant speed, and simultaneously record the elongation, deformation and changes in the bearing capacity of the lifting sling.

When the lifting sling shows obvious deformation, breakage or other abnormal conditions, stop loading immediately and record the maximum load-bearing capacity at this time.

Performance test

Repeated loading tests were conducted under different temperature conditions (such as low temperature, normal temperature, and high temperature) to evaluate the impact of temperature on the performance of the lifting slings.

Conduct wear resistance and corrosion resistance tests on the lifting slings to simulate the possible wear and corrosion conditions that may occur in actual usage environments.

Data Analysis and Evaluation

Analyze the test data, including the maximum load-bearing capacity, elongation rate, deformation condition, etc. of the lifting slings.

Evaluate the safety factor and service life of the flexible lifting sling based on the test results.

Compare with the product standards or design requirements to determine whether the lifting slings are qualified.

Precautions

When conducting load-bearing tests, it is essential to ensure the safety of the test personnel to prevent injuries caused by the sudden breakage or failure of the lifting slings.

During the test, the operating procedures should be strictly followed to avoid misoperation that may lead to distorted test results or damage to the equipment.

For substandard flexible lifting slings, they should be dealt with promptly to prevent them from entering the market or being used.

The load-bearing test of flexible lifting slings before they are put into storage is an important step to ensure their safety and reliability. Through strict testing procedures and data analysis, we can screen out flexible lifting slings with excellent performance, safety and reliability, providing a strong guarantee for industrial production and applications in other fields. Meanwhile, the load-bearing test also helps us understand the performance characteristics and limitations of the lifting sling, providing valuable reference information for future product improvement and optimization.
