The Crucial Role of Safety Coefficients and Elongation in Load Lifting Chains

Title: The Crucial Role of Safety Coefficients and Elongation in Load Lifting Chains

Subtitle: Understanding the Importance of Safety Coefficients and Proper Use in Preventing Accidents

Introduction:

Load-lifting chains play a pivotal role in various industries, including construction, manufacturing, and shipping. Ensuring the safe and efficient use of these chains is essential to prevent accidents, property damage, and loss of life. This article will discuss the importance of safety coefficients, elongation, and their implications for load-lifting chains' performance and user responsibility.

Safety Coefficients and Their Significance:

Load lifting chains are designed with three key safety coefficients: Working Load Limit (WLL), Manufacturing Test Force (MTF), and Breaking Load Limit (BLL). These coefficients are critical for maintaining the integrity and performance of the chains:

1. Working Load Limit (WLL): This represents the maximum load the chain can safely handle during operation. Users must not exceed this limit, as doing so may result in chain failure and potential accidents.
2. Manufacturing Test Force (MTF): This coefficient, set at 2.5 times the WLL, is the calibration load applied by the manufacturer to each chain link before dispatch. This testing ensures the chain's durability and compliance with industry standards.
3. Breaking Load Limit (BLL): Set at four times the WLL, this limit indicates the point at which the chain will break under extreme load. A minimum of 20% elongation is required before breakage, allowing users to detect excessive load and discontinue use.

Responsibilities of Users and Manufacturers:

Both users and manufacturers share responsibility for ensuring the safe use of load-lifting chains. Users must not exceed the WLL, as doing so may result in the seller disclaiming liability for accidents or damage. Manufacturers, on the other hand, must test each chain link at 2.5 times the WLL (MTF). However, they cannot perform a break test on every chain link, so they cannot accept responsibility for breaks over 2.5 times the WLL.

Working Load Coefficients and Lifting Angles:

The specified working loads for lifting chains are designed for 90-degree lifting. When creating load-lifting slings from chains, users should pay close attention to working load coefficients to ensure safe and proper use.

Preventing Accidents Through Proper Use:

Many accidents involving load-lifting chains result from improper use or failure to adhere to safety coefficients. By understanding and adhering to these safety measures, users can help prevent accidents and protect human life.

Quality Assurance and Liability Insurance at Force Chain:

At Force Chain production facilities, all lifting chains are manufactured and tested in accordance with industry standards. Our test devices are certified by accredited organizations, and our production and testing processes are audited by TUV at our request. Despite taking all necessary precautions, we carry product liability insurance to protect against unforeseen accidents.

Conclusion:

Safety coefficients and elongation play a crucial role in ensuring the safe and efficient use of load-lifting chains. By understanding these factors and adhering to industry standards, users can minimize the risk of accidents and protect human life. As a responsible manufacturer, Force Chain remains committed to producing high-quality lifting chains that meet or exceed these standards, thereby safeguarding the well-being of our customers and the wider community.
